A 2-chloro-1-(1-chlorocyclopropyl)ethanone purification device and processing technology

Abstract

This invention discloses a purification apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, relating to the field of chemical production technology. The invention includes a distillation vessel with a liquid inlet pipe fixedly connected to its top and a conduit fixedly connected to its top. Through the cooperation of components such as a rotating wheel, a belt, fan blades, and guide blocks, the rotation of the fan blades draws the vapor of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone into the conduit. This avoids the situation where, during the evaporation process, most of the evaporated gas remains at the top of the distillation vessel, with only a small portion flowing through the conduit to the external condenser. Therefore, the liquid formed from the gas at the top of the distillation vessel needs to be re-evaporated, thus reducing the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Simultaneously, the inclined surface at the bottom of the guide block guides the gas towards the conduit, increasing the speed at which the gas enters the conduit.

Description

Technical Field

[0001] This invention relates to the field of chemical production technology, specifically to a purification apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Background Technology

[0002] 2-Chloro-1-(1-Chlorocyclopropyl)ethyl ketone is an important organic chemical intermediate, commonly used in the synthesis of prothioconazole. As a key synthetic raw material, it has significant applications in the field of agricultural chemicals. Prothioconazole is a novel broad-spectrum triazole thione fungicide with significant control effects, widely used to control diseases in crops such as cereals, wheat, and legumes, especially demonstrating outstanding efficacy against pathogens. Its main mechanism of action is to effectively control crop diseases by inhibiting the growth and reproduction of pathogens.

[0003] Chinese patent CN221332786U discloses a purification device for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, including a distillation flask, an electric heating mantle, and a support frame, as well as a stirring assembly. The distillation flask is fitted with a top cover. The stirring assembly includes a motor, a transmission rod, a cross-shaped locking block, a connecting column, a connecting rod, a stirring paddle, a positioning rod, and a limiting ring. The motor is fixedly mounted on the top cover, and its power output is connected to the power input of the transmission rod. The lower end of the transmission rod is fixedly connected to the cross-shaped locking block. This patent uses the motor to drive the transmission rod to rotate, which in turn drives the connecting rod and the stirring paddle below to rotate, stirring the distillate and making it heated more evenly. The limiting ring, in conjunction with the positioning rod, limits the position of the connecting rod. The transmission rod and the connecting column are connected by the cross-shaped locking block for easy disassembly and quick replacement if the transmission assembly is damaged, making it convenient to use.

[0004] However, the current purification equipment has the following problems: during the evaporation process of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, most of the evaporated liquid will be located at the top of the distillation vessel, and a small portion will flow out from the conduit into the external vessel. This means that the liquid at the top of the distillation vessel needs to be re-evaporated, which reduces the evaporation rate. Therefore, we propose a 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone purification device and processing technology. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a purification apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a purification apparatus for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, comprising a distillation vessel, an inlet pipe fixedly connected to the top of the distillation vessel, a conduit fixedly connected to the top of the distillation vessel, a support frame fixedly connected to the top of the distillation vessel, a motor fixedly connected to the inner wall of the support frame, a rotating shaft fixedly connected to the output shaft of the motor, a stirring blade fixedly connected to the lower outer wall of the rotating shaft, and a guide device provided at the top of the inner wall of the distillation vessel. The apparatus includes a vertical rod, the top of which is fixedly connected to the top of the inner wall of the distillation vessel. A support ring is fixedly connected to the bottom of the vertical rod, and a fixing plate is fixedly connected to the inner wall of the support ring. A first rotating wheel is rotatably connected to the top of the fixing plate, and a second rotating wheel is fixedly connected to the outer wall of the rotating shaft. A belt drives the first and second rotating wheels together. A rotating rod is fixedly connected to the top of the first rotating wheel, and multiple fan blades are fixedly connected to the outer wall of the rotating rod. A guide block is fixedly connected to the inner wall of the distillation vessel, and the bottom of the guide block is inclined. The guide block is positioned below the conical groove. The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone to be purified is poured into the distillation vessel through the inlet pipe. The distillation vessel is then fixed in place by an external support. The fixed distillation vessel is then heated in a water bath. The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, upon heating, turns into water vapor, which flows through the conduit to an external condenser. Finally, the water vapor is condensed into water droplets and collected in the condenser. This process of heating the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone... When the motor is started, the output shaft of the motor causes the rotating shaft to rotate. The rotation of the rotating shaft drives the stirring blade to rotate, which in turn stirs the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the rotation of the rotating shaft also drives the second rotating wheel to rotate. The rotation of the second rotating wheel drives the first rotating wheel to rotate via a belt. The rotation of the first rotating wheel drives the rotating rod to rotate, which in turn drives the fan blade to rotate. The rotation of the fan blade draws the vapor of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone into the conduit.

[0007] According to the above technical solution, a conical block is fixedly connected to the bottom of the fixed plate. The outer wall of the conical block is provided with a spiral groove. Before the gas is drawn into the duct by the fan blade, the spiral groove on the surface of the conical block will cause the gas to float in a spiral shape.

[0008] According to the above technical solution, an auxiliary device is provided at the bottom inclined surface of the guide block. The auxiliary device includes a moving groove, which is opened at the bottom inclined surface of the guide block. A fixed rod is fixedly connected to the top of the inner wall of the moving groove, and a moving plate is slidably connected to the outer wall of the fixed rod. A spring is provided between the moving plate and the guide block. A long rod is fixedly connected to the bottom of the moving plate, and multiple fan plates are fixedly connected to the outer wall of the long rod. A vertical column is fixedly connected to the top of the moving plate. A limiting plate is fixedly connected to the outer wall of the rotating shaft, and a plate ball is fixedly connected to the bottom of the limiting plate. The rotation of the rotating shaft will drive the limiting plate to move forward. The rotation of the limiting plate causes the plate ball to rotate, which in turn causes it to contact the curved surface of the vertical post, causing the vertical post to move downwards. This downward movement of the vertical post causes the moving plate to move downwards along the outer wall of the fixed rod, stretching the spring. The downward movement of the moving plate causes the long rod to move downwards, which in turn causes multiple fan plates to move downwards. When the rotation of the plate ball no longer contacts the curved surface of the vertical post, the spring will reset itself through its own elastic force. The spring's reset will cause the moving plate to reset itself, which in turn causes the vertical post, long rod, and multiple fan plates to reset themselves. This process repeats, causing the multiple fan plates to move up and down repeatedly.

[0009] According to the above technical solution, the top of the vertical column is set to be arc-shaped, and the arc-shaped part of the vertical column is located on the displacement trajectory of the ball block.

[0010] According to the above technical solution, a striking device is provided at the bottom of the lowest fan plate. The striking device includes a U-shaped block. The top side of the U-shaped block is fixedly connected to the bottom of the fan plate. An arc plate is fixedly connected to the top of the side of the U-shaped block away from the fan plate. Several striking rods are fixedly connected to the top of the arc plate. When multiple fan plates are reset, the U-shaped block will move upward. The upward movement of the U-shaped block will cause the arc plate to move upward. The upward movement of the arc plate will cause the striking rods to move upward. The upward movement of the striking rods will strike the bottom of the guide block.

[0011] According to the above technical solution, multiple connecting rods are fixedly connected to the bottom of the arc plate, and the bottom of the multiple connecting rods is fixedly connected to the same fixing ring. Multiple support rods are fixedly connected to the bottom of the fixing ring, and several spiked balls are fixedly connected to the bottom of the multiple support rods. The multiple fan plates reciprocate back and forth, driving the U-shaped block to reciprocate back and forth. The reciprocating motion of the U-shaped block drives the arc plate to reciprocate back and forth. The reciprocating motion of the arc plate drives the connecting rods to reciprocate back and forth. The reciprocating motion of the connecting rods drives the fixing ring to reciprocate back and forth. The reciprocating motion of the fixing ring drives the support rods to reciprocate back and forth. The reciprocating motion of the support rods drives the spiked balls to reciprocate back and forth.

[0012] According to the above technical solution, the bottom inclined surface of the guide block is located on the displacement trajectory of the striking rod.

[0013] A purification process for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone includes the following steps;

[0014] S1. Pour the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone to be purified into the distillation vessel through the inlet pipe. Then, fix the distillation vessel with an external support. Then, heat the fixed distillation vessel in a water bath. The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone will turn into water vapor when heated. The water vapor will flow through the conduit to the external condenser. Finally, the water vapor will be condensed into water droplets and collected through the condenser.

[0015] S2. When heating 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, the operator starts the motor. The output shaft of the motor causes the rotating shaft to rotate, which in turn drives the stirring blade to rotate, thus stirring the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0016] S3. The rotation of the shaft will drive the second wheel to rotate, and the rotation of the second wheel will drive the first wheel to rotate via the belt. The rotation of the first wheel will drive the rotating rod to rotate.

[0017] S4. The rotation of the lever drives the fan blades to rotate, and the rotation of the fan blades will draw the vapor of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone into the conduit.

[0018] This invention provides a purification apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. It has the following beneficial effects:

[0019] (1) The present invention uses the combination of vertical rod, support ring, fixed plate, first rotating wheel, second rotating wheel, belt, rotating rod, fan blade, and guide block to make the rotation of the fan blade draw the vapor of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone into the conduit, thereby avoiding the situation where most of the evaporated gas is located at the top of the distillation vessel and a small portion flows to the external condenser through the conduit during the evaporation process of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Therefore, the liquid that is turned from gas at the top of the distillation vessel needs to be re-evaporated, thereby reducing the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the inclined surface at the bottom of the guide block will guide the gas towards the conduit, thereby increasing the speed at which the gas enters the conduit. At the same time, the combination of conical block and spiral groove will make the gas float in a spiral shape before it is drawn into the conduit by the fan blade. The spiral floating of the gas will correspond to the shape of the gas drawn by the fan blade, thereby further improving the efficiency of the fan blade in drawing gas.

[0020] (2) The present invention uses the cooperation of a moving groove, a fixed rod, a moving plate, a spring, a long rod, a fan plate, a vertical column, a limiting plate, and a plate ball block to make the moving plate reset, which drives the vertical column, the long rod, and multiple fan plates to reset. This process is repeated, so that multiple fan plates move up and down. When multiple fan plates move upward, the steam will drift to the bottom of the bottom fan plate. When multiple fan plates move downward, the steam below the bottom fan plate will drift to the guide block conical groove. This allows the fan blades to increase the extraction speed of steam and reduce the amount of steam adhering to the bottom of the guide block slope, thereby increasing the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, through the cooperation of the fan plates and the long rod, the water droplets at the bottom of the bottom fan plate can fall into the distillation kettle more quickly while multiple fan plates are moving back and forth, thereby ensuring the purification efficiency of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0021] (3) In this invention, the U-shaped block, the arc plate, and the striking rod work together to move the arc plate upward, which in turn moves the striking rod upward. The upward movement of the striking rod will strike the bottom of the guide block, thereby accelerating the return of the liquid generated by the vapor at the bottom of the guide block to the inside of the distillation vessel, thus accelerating the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the connecting rod, the fixing ring, the support rod, the spiked ball, and the stirring blade work together to make the fixing ring reciprocate, which in turn drives the support rod to reciprocate. The reciprocating motion of the support rod drives the spiked ball to reciprocate. The reciprocating motion of the spiked ball will break the bubbles generated during the purification of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, thereby reducing the situation where the presence of bubbles will reduce the heat transfer efficiency of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figures 1-8One embodiment of the present invention is: a purification apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)acetone, comprising a distillation kettle 1, an inlet pipe 2 fixedly connected to the top of the distillation kettle 1, a conduit 3 fixedly connected to the top of the distillation kettle 1, the end of the conduit 3 away from the distillation kettle 1 being fixedly connected to an external condenser pipe, a support frame 4 fixedly connected to the top of the distillation kettle 1, a motor 5 fixedly connected to the inner wall of the support frame 4, a rotating shaft 6 fixedly connected to the output shaft of the motor 5, a stirring blade 10 fixedly connected to the lower outer wall of the rotating shaft 6, a guide device 7 provided on the top of the inner wall of the distillation kettle 1, the guide device 7 comprising a vertical rod 71, the top of the vertical rod 71 fixedly connected to the top of the inner wall of the distillation kettle 1, a support ring 72 fixedly connected to the bottom of the vertical rod 71, a fixing plate 73 fixedly connected to the inner wall of the support ring 72, a rotating wheel 74 rotatably connected to the top of the fixing plate 73, and a rotating wheel 75 fixedly connected to the outer wall of the rotating shaft 6, the rotating wheel 74 and the rotating wheel 75 being connected to each other. A belt 76 is connected between the 5 parts for transmission. A rotating rod 77 is fixedly connected to the top of the rotating wheel 74. Multiple fan blades 78 are fixedly connected to the outer wall of the rotating rod 77. A guide block 79 is fixedly connected to the inner wall of the distillation vessel 1. The bottom of the guide block 79 is inclined. A conical groove is opened on the guide block 79 below the conduit 3. Through the above structure, the rotation of the fan blades 78 will draw the vapor of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone into the conduit 3. This avoids the situation where most of the evaporated gas will be located at the top of the distillation vessel 1 and a small portion will flow to the external condenser through the conduit 3 during the evaporation process of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Therefore, the liquid that is turned from gas at the top of the distillation vessel 1 needs to be re-evaporated, which reduces the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the inclined surface at the bottom of the guide block 79 will guide the gas towards the conduit 3, thereby increasing the speed at which the gas enters the conduit 3.

[0033] A conical block 710 is fixedly connected to the bottom of the fixed plate 73. The outer wall of the conical block 710 is provided with a spiral groove 711. With the above structure, before the gas is drawn into the duct 3 by the fan blade 78, the spiral groove 711 on the surface of the conical block 710 will cause the gas to float in a spiral shape. The spiral floating of the gas will correspond to the shape of the gas drawn by the fan blade 78, thereby further improving the efficiency of the fan blade 78 in drawing gas.

[0034] An auxiliary device 8 is provided at the bottom inclined surface of the guide block 79. The auxiliary device 8 includes a moving groove 81, which is located at the bottom inclined surface of the guide block 79. A fixing rod 82 is fixedly connected to the top of the inner wall of the moving groove 81. A moving plate 83 is slidably connected to the outer wall of the fixing rod 82. A spring 84 is provided between the moving plate 83 and the guide block 79. A long rod 85 is fixedly connected to the bottom of the moving plate 83. Multiple fan plates 86 are fixedly connected to the outer wall of the long rod 85. A vertical column 87 is fixedly connected to the top of the moving plate 83. A limiting plate 88 is fixedly connected to the outer wall of the rotating shaft 6. A plate ball block 89 is fixedly connected to the bottom of the limiting plate 88. The top of the vertical column 87 is arc-shaped. The arc-shaped section is located on the displacement trajectory of the plate ball block 89. Through the above-mentioned structure, the reset of the moving plate 83 drives the vertical column 87, the long rod 85, and multiple fan plates 86 to reset. This process repeats, causing the multiple fan plates 86 to move up and down. When the multiple fan plates 86 move upward, the steam will drift below the bottom fan plate 86. When the multiple fan plates 86 move downward, the steam below the bottom fan plate 86 will drift towards the conical groove of the guide block 79. This allows the fan blades 78 to increase the steam extraction speed and reduce the amount of steam adhering to the bottom of the inclined surface of the guide block 79, thereby increasing the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0035] In use, the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone to be purified is poured into the distillation vessel 1 through the inlet pipe 2. The distillation vessel 1 is then fixed in place by an external support. The fixed distillation vessel 1 is then heated in a water bath. The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone turns into water vapor upon heating, which flows through the conduit 3 to the external condenser. Finally, the water vapor is condensed into water droplets and collected through the condenser. While the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone is being heated, the operator starts the motor 5. The output shaft of the motor 5 causes the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the stirring blade 10 to rotate, thus stirring the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Simultaneously, the rotation of the rotating shaft 6 drives the rotating wheel 75 to rotate. The rotation of the rotating wheel 75 drives the rotating wheel 74 to rotate via the belt 76. The rotation of the rotating wheel 74 drives the rotating rod 77 to... The rotation of the rotating rod 77 drives the fan blade 78 to rotate, which draws the vapor of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone into the conduit 3. This avoids the situation where most of the evaporated gas remains at the top of the distillation vessel 1, with only a small portion flowing through the conduit 3 to the external condenser. As a result, the liquid formed from the gas at the top of the distillation vessel 1 needs to be re-evaporated, thus reducing the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the inclined surface at the bottom of the guide block 79 guides the gas towards the conduit 3, thereby increasing the speed at which the gas enters the conduit 3. Before the gas is drawn into the conduit 3 by the fan blade 78, the spiral groove 711 on the surface of the conical block 710 causes the gas to float in a spiral shape. The spiral movement of the gas corresponds to the shape of the gas drawn by the fan blade 78, thereby further improving the efficiency of the fan blade 78 in drawing the gas.

[0036] The rotation of shaft 6 causes the limiting plate 88 to rotate, which in turn causes the ball block 89 to rotate. The rotation of the ball block 89 causes it to contact the curved surface of the vertical column 87, thus moving the vertical column 87 downwards. This downward movement of the vertical column 87 causes the moving plate 83 to move downwards along the outer wall of the fixed rod 82, stretching the spring 84. The downward movement of the moving plate 83 causes the long rod 85 to move downwards, which in turn causes multiple fan plates 86 to move downwards. When the rotation of the ball block 89 no longer contacts the curved surface of the vertical column 87, the spring 84 will return to its original position due to its own elasticity. This return of the spring 84 causes the moving plate 83 to return to its original position, which in turn causes the vertical column 87, the long rod 85, and the multiple fan plates 86 to move downwards. 6. Reset the process, repeating this process to cause multiple fan blades 86 to move up and down. When the multiple fan blades 86 move upward, they cause the steam to drift below the bottommost fan blade 86. When the multiple fan blades 86 move downward, they cause the steam below the bottommost fan blade 86 to drift towards the conical groove of the guide block 79. This allows the fan blades 78 to increase the steam extraction speed and reduce the amount of steam adhering to the bottom of the inclined surface of the guide block 79, thereby increasing the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the reciprocating motion of the multiple fan blades 86 can also cause the water droplets at the bottom of the bottommost fan blade 86 to fall into the distillation vessel 1 more quickly, thus ensuring the purification efficiency of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0037] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a striking device 9 is provided at the bottom of the lowest fan plate 86. The striking device 9 includes a U-shaped block 91. The top side of the U-shaped block 91 is fixedly connected to the bottom of the fan plate 86. An arc plate 92 is fixedly connected to the top of the side of the U-shaped block 91 away from the fan plate 86. Several striking rods 93 are fixedly connected to the top of the arc plate 92. The bottom slope of the guide block 79 is located on the displacement trajectory of the striking rods 93. With the above structure, the arc plate 92 moves upward, driving the striking rods 93 to move upward. The upward movement of the striking rods 93 will strike the bottom of the guide block 79, thereby accelerating the return of the liquid generated by the vapor at the bottom of the guide block 79 to the inside of the distillation kettle 1, thereby accelerating the purification speed of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0038] Multiple connecting rods 94 are fixedly connected to the bottom of the arc plate 92. The bottom of the multiple connecting rods 94 is fixedly connected to the same fixing ring 95. The bottom of the fixing ring 95 is fixedly connected to multiple support rods 96. The bottom of the multiple support rods 96 is fixedly connected to several spike balls 97. Through the above structure, the reciprocating motion of the fixing ring 95 drives the reciprocating motion of the support rods 96, which in turn drives the reciprocating motion of the spike balls 97. The reciprocating motion of the spike balls 97 breaks up the bubbles generated during the purification of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, thereby reducing the possibility that the presence of bubbles would reduce the thermal conductivity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0039] In use, as multiple fan plates 86 reset, they drive the U-shaped block 91 upward. The upward movement of the U-shaped block 91 drives the arc plate 92 upward, which in turn drives the striking rod 93 upward. The upward movement of the striking rod 93 strikes the bottom of the guide block 79, thereby accelerating the return of the liquid generated by the vapor at the bottom of the guide block 79 to the distillation vessel 1, thus speeding up the purification of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. During the heating process of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, a large number of accumulated bubbles are generated. Therefore, the reciprocating motion of the multiple fan plates 86 simultaneously drives the U-shaped block 91 upward. 1. The U-shaped block 91 reciprocates, driving the arc plate 92 to reciprocate. The arc plate 92 reciprocates, driving the connecting rod 94 to reciprocate. The connecting rod 94 reciprocates, driving the fixing ring 95 to reciprocate. The fixing ring 95 reciprocates, driving the support rod 96 to reciprocate. The support rod 96 reciprocates, driving the spiked ball 97 to reciprocate. The reciprocating motion of the spiked ball 97 breaks up the bubbles generated during the purification of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, thereby reducing the presence of bubbles that would reduce the thermal conductivity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0040] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
