[0002] Epoxy-terminated allyl alcohol ethers are important organic synthesis intermediates widely used in resins, coatings, adhesives, and other fields. They serve as a key link between basic chemical raw materials and high-value-added end products, playing an irreplaceable role in fine chemicals, electronics, aerospace, and other industries. The preparation process of epoxy-terminated allyl alcohol ethers typically involves the reaction of allyl alcohol ethers with raw materials such as epichlorohydrin under specific conditions. Solution preparation is a crucial step before preparation, requiring the precise mixing of various liquid raw materials, such as allyl alcohol ethers, catalysts, epichlorohydrin, and solvents, under controlled temperature conditions.

[0003] The preparation of epoxy-terminated allyl alcohol ethers requires a constant temperature environment. Existing preparation reactors typically have a jacketed temperature control layer on the outside of the reactor body, which is connected to a constant temperature circulation system for temperature control. However, the raw solution located in the center of the reactor cannot be quickly adjusted in temperature. In severe cases, untimely temperature adjustment can cause the raw solution to deteriorate, thereby reducing the quality and efficiency of epoxy-terminated allyl alcohol ether preparation.

[0017] Example 1

[0018] like Figures 1 to 4 As shown, this utility model proposes a liquid preparation device for the preparation of epoxy-terminated allyl alcohol ether, including a reaction vessel body 1, a rotating shaft 2, a first flow chamber 202, a second flow chamber 203, a stirring blade 204, and a liquid outlet mechanism. The side wall of the reaction vessel body 1 is provided with a jacketed temperature control layer, which is existing technology. A temperature sensor is installed on the reaction vessel body 1, with the sensor's detection end extending into the interior of the reaction vessel body 1 for real-time monitoring of the internal liquid temperature. The rotating shaft 2 is driven to rotate and connected to the top cover in the reaction vessel body 1 via a drive mechanism. The top cover is detachably connected to the top of the reaction vessel body 1. The drive mechanism consists of a motor and a gear transmission assembly. The gear transmission assembly consists of two sets of meshing gears. One set of gears is installed on the outer wall of the rotating shaft 2, and the other set of gears is driven to rotate by the motor. The motor power is matched according to the volume of the reaction vessel body 1. An input valve is adjustablely installed at the top of the rotating shaft 2. Valve 201; First flow chamber 202 is disposed in rotating shaft 2, and the output end of input valve 201 extends into first flow chamber 202; Multiple sets of second flow chambers 203 are disposed, and the multiple sets of second flow chambers 203 are evenly distributed in rotating shaft 2, of which the highest set of second flow chambers 203 is connected to first flow chamber 202; Multiple sets of stirring blades 204 are disposed, and the stirring blades 204 are U-shaped, and the multiple sets of stirring blades 204 are evenly installed on both sides of the outer circumference of rotating shaft 2, of which the output end of stirring blade 204 on one side is connected to the input end of stirring blade 204 on the other side through second flow chamber 203. It should be noted that a flow limiting valve is provided at the connection between second flow chamber 203 and stirring blade 204 to ensure that the medium flow rate of each set of stirring blades 204 is consistent. The flow limiting valve is not shown; Liquid outlet mechanism is disposed at the bottom of reactor body 1, and the output end of rotating shaft 2 is detachably connected to liquid outlet mechanism.

[0019] Furthermore, a housing 101 is installed on the top cover of the reactor body 1, and a drive mechanism is installed in the housing 101. An input valve 201 is installed on the housing 101 and extends through the housing 101. A three-way valve is installed at the input end of the input valve 201. The two sets of input ends of the three-way valve are respectively connected to an external coolant supply mechanism and an external steam supply mechanism. The output end of the input valve 201 is rotatably connected to the rotating shaft 2.

[0020] Furthermore, multiple sets of guide plates 205 are evenly installed in the inner cavity of the stirring blade 204. The multiple sets of guide plates 205 are staggered along the inner cavity of the stirring blade 204, guiding the flow trajectory of the coolant or steam entering the inner cavity into a continuous S-shape, thus prolonging the residence time in the inner cavity.

[0021] In this embodiment, the liquid raw materials required for the preparation of epoxy-terminated allyl alcohol ether are proportionally transported into the reactor body 1. The output ends of the external coolant supply mechanism and the external steam supply mechanism are respectively connected to the two input ends of the three-way valve on the input valve 201. The controller starts the drive mechanism to drive the rotating shaft 2 to rotate, thereby driving multiple sets of stirring blades 204 to rotate and stir and mix the liquid raw materials in the reactor body 1 evenly. The temperature of the liquid in the reactor body 1 is controlled by the jacketed temperature control layer outside the reactor body 1. At the same time, when the temperature sensor detects that the temperature of the liquid inside the reactor body 1 is higher or lower than the set safety threshold, Coolant or steam is supplied to the input valve 201 through an external coolant supply mechanism or an external steam supply mechanism, allowing it to enter through the input valve 201 and travel within the inner cavity of each set of stirring blades 204, and finally be discharged through the liquid outlet mechanism. As the rotating shaft 2 drives the rotation of multiple sets of stirring blades 204, the temperature control medium can fully contact the liquid inside the reactor body 1 through the stirring blades 204, absorbing and dissipating heat from the raw materials or heating the raw materials. This can then work in conjunction with the jacketed temperature control layer to quickly control the temperature of the raw material liquid until the temperature sensor detects that the temperature of the liquid inside the reactor body 1 has reached the required temperature threshold for the reaction.

[0022] Example 2

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes a liquid preparation device for the preparation of epoxy-terminated allyl alcohol ether. Compared with Embodiment 1, the liquid outlet mechanism includes a rotating pipe 3 and an output valve 4. The rotating pipe 3 is rotatably connected to the reactor body 1 through a bearing. Two sets of stirring plates 301 are symmetrically installed on the outer circumference of the rotating pipe 3. The stirring plates 301 are in contact with the inner wall of the bottom end of the reactor body 1 and the inner side wall of the reactor body 1, which facilitates the stirring of the raw materials at the bottom end of the reactor body 1 and avoids precipitation. The output valve 4 is connected to the outside of the bottom end of the reactor body 1 through a bracket. The rotating pipe 3 is rotatably connected to the inner wall of the output valve 4 through a bearing. It should be noted that the bearings in this technical solution are all equipped with sealing mechanisms to avoid liquid leakage. The output end of the output valve 4 is connected to an external recovery mechanism to facilitate the recovery and reuse of coolant or steam.

[0024] Furthermore, a connecting pipe 206 is installed at the bottom of the rotating shaft 2. The connecting pipe 206 is connected to a set of second flow chambers 203 at the lowest end of the rotating shaft 2. The connecting pipe 206 is square, and a sealing seat 207 is provided on the outer wall of the connecting pipe 206. The sealing seat 207 abuts against the top end of the rotating tube 3. The connecting pipe 206 is inserted into the rotating tube 3. The top end of the rotating tube 3 is provided with a square opening that slides with the connecting pipe 206. An O-ring is provided at the abutment point between the sealing seat 207 and the rotating tube 3. It should be noted that guide marks are provided on the top end of the rotating shaft 2 and the side wall of the output valve 4 to facilitate the insertion and connection of the connecting pipe 206 and the rotating tube 3.

[0025] In this embodiment, the rotating shaft 2 and the stirring blade 204 are inserted into the vessel body, so that the connecting pipe 206 is inserted into the rotating tube 3 until the sealing seat 207 is pressed against the rotating tube 3. At this time, the connecting pipe 206 is connected to the output valve 4, and the temperature control medium in the rotating shaft 2 finally flows into the rotating tube 3 and is discharged along the output valve 4. The rotating shaft 2 and the liquid outlet mechanism are easy to disassemble and install, and it is convenient to disassemble and repair the rotating shaft 2 and the stirring blade 204.
