Description

Technical Field

[0001] This invention relates to the field of musk synthesis technology, and in particular to a method for preparing industrially produced musk. Background Technology

[0002] Tuna Musk is a daily-use fragrance, belonging to the bicyclic naphthyl musk class. It has a strong powdery aroma, excellent fragrance quality, elegant fragrance, and long-lasting scent. This product has strong diffusion and good compatibility. It is stable in acidic and alkaline media, does not easily change color, and has strong adhesion to fibers. It is suitable for high-end cosmetics such as soaps and face powders.

[0003] The invention patent with authorization announcement number CN 102050715 B discloses a method for preparing industrial turpentine musk. Using p-isopropyltoluene and 2,3-dimethyl-1-butene as raw materials and tert-butyl chloride as a hydrogen absorber, an intermediate 1,1,3,4,4,6-hexamethyltetrahydronaphthalene is synthesized via Friedel-Crafts alkylation. Then, the intermediate is used as a raw material to undergo Friedel-Crafts acylation with acetyl chloride in dichloromethane solvent to obtain the product turpentine musk. Compared with existing methods and technologies, this method is simple to operate, has a fast reaction rate, and the product purification only requires thermal dissolution of the pigment with anhydrous ethanol, eliminating the need for distillation and fractionation, and achieving high yield, thus realizing industrial production.

[0004] After separating the organic layers in reactant A and reactant B, the above preparation method requires multiple washings with saturated sodium chloride for the organic layer in reactant A, and multiple washings with unsaturated sodium carbonate followed by multiple washings with saturated sodium chloride for the organic layer in reactant B. In this process, due to the large volume of organic layers processed in industrial production, a large amount of unsaturated sodium carbonate and saturated sodium chloride are required. After each washing, a long feeding time is needed before the next washing can be completed. This consumes a significant amount of time in practical applications, thus reducing the efficiency of organic layer processing.

[0023] Preferably, the preparation method of the industrial turpentine musk specifically includes the following steps:

[0024] S1. Using p-isopropyltoluene, 2,3-dimethyl-1-butene, and tert-butyl chloride as raw materials, a reaction solution A is formed. Using anhydrous aluminum trichloride, concentrated sulfuric acid, hydrochloric acid, and cyclohexane as raw materials, a reaction mixture A is formed. The reaction solution A is added dropwise to the reaction mixture A to form reactant A. The reactant is added to brine and stirred continuously to form a mixed liquid A. The mixed liquid A is added into the washing shell through the feed pipe. The mixed liquid A falls to the bottom of the inner cavity of the washing shell and is filtered by the filter plate to obtain organic layer A.

[0025] S2. While performing the above operation, saturated sodium chloride is added to the second annular storage chamber through the second inlet pipe. After the mixed liquid A is filtered, the addition of saturated sodium chloride is completed.

[0026] S3. Start the drive motor so that the drive motor drives the drive shaft to rotate clockwise. At this time, the drive shaft drives the reciprocating screw to rotate synchronously. When the reciprocating screw rotates, it drives the lifting cylinder to descend synchronously through the lifting collar and connecting rod. As the lifting cylinder continues to descend, the saturated sodium chloride in the second annular liquid storage chamber enters the interior of the lifting cylinder through the opening at the top of the lifting cylinder, and then falls to the top of the organic layer A, thus completing one saturated sodium chloride output.

[0027] S4. Switch the drive direction of the drive motor so that the drive motor drives the drive shaft to rotate counterclockwise. At this time, due to the limitation of the overrunning clutch, the reciprocating screw does not rotate. When the drive motor rotates, it drives the arc-shaped guide plate to rotate through the fixed collar. At the same time, the arc-shaped guide plate drives multiple stirring support rods to rotate through the stirring main rod, thereby stirring the organic layer A mixed with saturated sodium chloride, thus completing the first washing of the organic layer A.

[0028] S5. Repeatedly switch the drive direction of the drive motor multiple times to complete multiple washes of the organic layer A. At the same time, as the lifting drum continues to descend, when the descent distance of the lifting drum reaches the first threshold, the lifting drum drives the support rod to push the inner annular sleeve plate. The inner annular sleeve plate drives the threaded sleeve to descend through the outer annular sleeve plate. When the threaded sleeve descends, it drives the stirring main rod to rotate. When the stirring main rod rotates, it drives multiple stirring support rods to rotate around the stirring main rod as the axis, thereby better stirring the organic layer being washed.

[0029] S6. When the lifting cylinder descends to the second threshold, the inner annular sleeve drives the threaded sleeve to descend to the top of the limiting sleeve. At this time, the inner annular sleeve can no longer descend. Then, driven by the lifting cylinder, the support rod is pushed upward. When the lifting cylinder descends to the third threshold, the bottom of the lifting cylinder contacts the top of the inner annular sleeve, and the inner annular sleeve closes the bottom opening of the lifting cylinder. At the same time, the lifting sleeve moves to the lowest end of the reciprocating thread on the outside of the reciprocating screw.

[0030] S7. Subsequently, anhydrous sodium sulfate is manually added to the inside of the washing shell to dry the washed organic layer A. Then, the electric heating element is activated, and air inside the washing shell is drawn in through the negative pressure tube. At this time, the bottom of the inner cavity of the washing shell is under negative pressure, and the organic layer A is distilled under reduced pressure to obtain intermediate 1,1,3,4,4,6-hexamethyltetrahydronaphthalene.

[0031] S8. The drive motor drives the drive shaft to rotate counterclockwise, which in turn causes the fixed collar to rotate multiple arc-shaped guide plates. The arc-shaped guide plates push the intermediate 1,1,3,4,4,6-hexamethyltetrahydronaphthalene, so that it is output through the discharge pipe.

[0032] S9. Using 1,1,3,4,4,6-hexamethyltetrahydronaphthalene and acetyl chloride as raw materials, a reaction solution B is formed. Using anhydrous aluminum trichloride and dichloromethane as raw materials, a reaction mixture B is formed. The reaction solution B is added dropwise to the reaction mixture B to form reactant B. The reactant is added to brine and stirred continuously to form a mixed liquid B. The mixed liquid B is added into the washing shell through the feed pipe. The mixed liquid A falls to the bottom of the inner cavity of the washing shell and is filtered by the filter plate to obtain the organic layer B.

[0033] S10. When performing the above operation, unsaturated sodium carbonate and saturated sodium chloride are added to the first annular storage chamber and the second annular storage chamber through the first liquid inlet pipe and the second liquid inlet pipe, respectively. After the mixture liquid B is filtered, the addition of unsaturated sodium carbonate and saturated sodium chloride is completed.

[0034] S11. Repeat S3-S7 above to obtain crude 7-acetyl-1,1,3,4,4,6-hexamethyltetrahydronaphthalene. Mix the crude 7-acetyl-1,1,3,4,4,6-hexamethyltetrahydronaphthalene with anhydrous ethanol and let stand until solid precipitates. Then filter to obtain tuna musk.

[0035] The technical effects and advantages of this invention are as follows:

[0036] This invention incorporates a separating mechanism, a driving mechanism, a stirring and discharging mechanism, a triggering mechanism, a lifting liquid supply mechanism, and a sealing auxiliary mechanism. The driving mechanism intermittently drives the lifting liquid supply mechanism, causing the separating mechanism to intermittently supply saturated sodium chloride and unsaturated sodium carbonate to the bottom of the washing shell cavity via the lifting liquid supply mechanism. This rapidly completes the washing of organic layers A and B. Simultaneously, as the lifting liquid supply mechanism is continuously driven, it further drives the stirring and discharging mechanism through the sealing auxiliary mechanism and the triggering mechanism, enhancing the stirring effect. Finally, with the continuous movement of the lifting liquid supply mechanism, the sealing auxiliary mechanism is eventually triggered, sealing the bottom of the lifting liquid supply mechanism and creating a closed environment at the bottom of the washing shell cavity. This provides conditions for subsequent vacuum distillation. Compared to similar devices or methods in the prior art, this invention can complete the washing of organic layers A and B more quickly, and vacuum distillation can be performed without transferring the products, thus significantly improving the efficiency of musk preparation and making it more suitable for industrial production.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] This invention provides, for example Figure 1-4 The present invention discloses a method for preparing industrial musk, wherein the method is implemented using an industrial musk preparation device, the industrial musk preparation device includes a washing mechanism 1, and a separating mechanism 2 is provided at the top of the inner cavity of the washing mechanism 1. The separating mechanism 2 forms a first annular liquid storage cavity and a second annular liquid storage cavity at the top of the inner cavity of the washing mechanism 1, wherein the first annular liquid storage cavity is located above the second annular liquid storage cavity.

[0045] The washing mechanism 1 is provided with a drive mechanism 3 at its bottom and inside. The drive mechanism 3 is connected to a stirring and discharging mechanism 4 and a lifting liquid supply mechanism 6 from bottom to top on its outer side. The stirring and discharging mechanism 4 is provided with a trigger mechanism 5 at its top. The lifting liquid supply mechanism 6 is provided with two closed auxiliary mechanisms 7 at its inner bottom.

[0046] like Figure 2 As shown, the washing mechanism 1 includes a washing housing 11, a filter plate 12, a feed pipe 13, a liquid outlet pipe 14, a discharge pipe 15, a negative pressure pipe 16, and an electric heating element 17. The filter plate 12 is fixedly disposed at the bottom of the inner cavity of the washing housing 11. The feed pipe 13 and the liquid outlet pipe 14 are fixedly disposed through the left side of the washing housing 11 from top to bottom. The discharge pipe 15 and the negative pressure pipe 16 are fixedly disposed through the right side of the washing housing 11 from bottom to top. The electric heating element 17 is fixedly sleeved on the bottom outer side of the washing housing 11.

[0047] like Figure 2 and Figure 4As shown, the separating mechanism 2 includes a first separating plate 21, a second separating plate 22, an annular guide platform 23, a first liquid inlet pipe 24, a second liquid inlet pipe 25, and a pressure equalizing pipe 26. The first separating plate 21 and the second separating plate 22 are fixedly arranged on the top inner side of the washing housing 11 from top to bottom. There are two annular guide platforms 23, which are respectively fixedly arranged on the top of the first separating plate 21 and the second separating plate 22. The first liquid inlet pipe 24 and the second liquid inlet pipe 25 are fixedly arranged through the top left side of the washing housing 11 from top to bottom. There are two pressure equalizing pipes 26, which are both fixedly arranged through the top right side of the washing housing 11.

[0048] By setting up the above structure, unsaturated sodium carbonate and saturated sodium chloride can be added to the first annular storage chamber and the second annular storage chamber through the first liquid inlet pipe 24 and the second liquid inlet pipe 25.

[0049] like Figure 3 As shown, the drive mechanism 3 includes a drive motor 31, a drive shaft 32, and a reciprocating screw 33. The drive motor 31 is fixedly mounted on the bottom of the washing housing 11. The drive shaft 32 is located inside the washing housing 11 and is connected to the drive motor 31 in a transmission manner. The reciprocating screw 33 is connected to the top of the drive shaft 32 through an overrunning clutch. The top of the reciprocating screw 33 penetrates the inner wall of the washing housing 11 and extends to the outer side of the washing housing 11. The reciprocating screw 33 is rotatably connected to the washing housing 11 through a bearing.

[0050] By setting the above structure, the drive motor 31 drives the drive shaft 32 to rotate clockwise, and the reciprocating screw 33 rotates synchronously. When the drive motor 31 drives the drive shaft 32 to rotate counterclockwise, the reciprocating screw 33 does not rotate due to the limitation of the overrunning clutch.

[0051] like Figure 3 As shown, the mixing and discharging mechanism 4 includes a fixed collar 41, an arc-shaped guide plate 42, and multiple sets of mixing components. Each mixing component includes a mixing main rod 43, mixing support rods 44, and a limiting collar 45. The fixed collar 41 is fixedly sleeved on the top outer side of the drive shaft 32. Multiple arc-shaped guide plates 42 are provided and are evenly fixedly arranged on the outer side of the fixed collar 41. Multiple sets of mixing components are rotatably arranged on the top of the multiple arc-shaped guide plates 42. The bottom end of the mixing main rod 43 is rotatably nested on the top of the arc-shaped guide plate 42 through a bearing. Multiple mixing support rods 44 are provided and are evenly fixedly arranged on both sides of the mixing main rod 43. The limiting collar 45 is fixedly sleeved on the middle outer side of the mixing main rod 43.

[0052] By setting the above structure, when the drive motor 31 rotates, it drives the arc-shaped guide plate 42 to rotate through the fixed collar 41. At the same time, the arc-shaped guide plate 42 drives multiple stirring support rods 44 to rotate through the stirring main rod 43, thereby stirring the organic layer A mixed with saturated sodium chloride, the organic layer B mixed with saturated sodium chloride, or the organic layer B mixed with unsaturated sodium carbonate.

[0053] like Figure 3 As shown, the triggering mechanism 5 includes a mounting collar 51, an inner annular sleeve 52, a first spring 53, an outer annular sleeve 54, and a threaded sleeve 55. The mounting collar 51 is rotatably sleeved on the bottom outer side of the reciprocating screw 33 via a bearing. The inner annular sleeve 52 is slidably sleeved on the middle outer side of the reciprocating screw 33. The first spring 53 is sleeved on the outer side of the reciprocating screw 33 and located between the mounting collar 51 and the inner annular sleeve 52. The outer annular sleeve 54 is rotatably sleeved on the outer side of the inner annular sleeve 52 via a bearing. Multiple threaded sleeves 55 are provided, and multiple threaded sleeves 55 are uniformly fixedly and penetrate through the top of the outer annular sleeve 54 and are respectively sleeved on the outer side of multiple stirring rods 43.

[0054] By setting up the above structure, when the inner annular sleeve 52 is pressed down, the inner annular sleeve 52 drives the threaded sleeve 55 to descend through the outer annular sleeve 54. When the threaded sleeve 55 descends, it drives the stirring main rod 43 to rotate. When the stirring main rod 43 rotates, it drives multiple stirring support rods 44 to rotate around the stirring main rod 43 as the axis, thereby better stirring the organic layer being washed.

[0055] like Figure 4 As shown, the lifting liquid supply mechanism 6 includes a lifting cylinder 61, a lifting collar 62, and connecting rods 63. The lifting cylinder 61 is slidably nested inside the first partition plate 21 and the second partition plate 22. Strip-shaped sliders are fixedly provided on both sides of the lifting cylinder 61. Limiting grooves are provided on the inner sides of the first partition plate 21 and the second partition plate 22. The strip-shaped sliders are slidably disposed inside the limiting grooves. The lifting collar 62 is sleeved on the outer side of the reciprocating screw 33 and is connected to the reciprocating screw 33 through a reciprocating thread. Multiple connecting rods 63 are provided, and the multiple connecting rods 63 are evenly fixedly disposed on the outer side of the lifting collar 62 and are all fixedly connected to the inner wall of the lifting cylinder 61.

[0056] By setting the above structure, after the lifting collar 62 is driven by the reciprocating screw 33, the lifting collar 62 drives the lifting cylinder 61 to descend intermittently through the connecting rod 63, thereby causing the saturated sodium chloride in the second annular liquid storage chamber or the unsaturated sodium carbonate in the first annular liquid storage chamber and the saturated sodium chloride in the second annular liquid storage chamber to be intermittently input into the bottom of the inner cavity of the washing shell 11.

[0057] like Figure 4 As shown, the closed auxiliary mechanism 7 includes a mounting plate 71, a support rod 72, an end plate 73, and a second spring 74. The mounting plate 71 is fixedly connected to the inner wall of the lifting cylinder 61. The support rod 72 passes through the mounting plate 71 and is slidably connected to the mounting plate 71. The end plate 73 is fixedly disposed on the top end of the support rod 72. The second spring 74 is sleeved on the outside of the support rod 72. One end of the second spring 74 is fixedly connected to the mounting plate 71, and the other end is fixedly connected to the end plate 73.

[0058] By setting up the above structure, when the inner annular sleeve 52 can no longer descend, the support rod 72 is compressed and rises, and then pulls the second spring 74 through the end plate 73. As the support rod 72 continues to rise, the inner annular sleeve 52 seals the bottom of the lifting cylinder 61, thereby forming a closed environment at the bottom of the inner cavity of the washing shell 11, providing conditions for subsequent vacuum distillation.

[0059] Example 2

[0060] The preparation method of the industrial musk specifically includes the following steps:

[0061] S1. Using p-isopropyltoluene, 2,3-dimethyl-1-butene, and tert-butyl chloride as raw materials, a reaction solution A is formed by mixing them. Using anhydrous aluminum trichloride, concentrated sulfuric acid, hydrochloric acid, and cyclohexane as raw materials, a reaction mixture A is formed by mixing them. The reaction solution A is added dropwise to the reaction mixture A to form reactant A. The reactant is added to brine and stirred continuously to form a mixed liquid A. The mixed liquid A is added into the washing shell 11 through the feed pipe 13. The mixed liquid A falls to the bottom of the inner cavity of the washing shell 11 and is filtered by the filter plate 12 to obtain an organic layer A.

[0062] S2. While performing the above operation, saturated sodium chloride is added to the second annular storage chamber through the second liquid inlet pipe 25. The addition of saturated sodium chloride is completed after the mixed liquid A is filtered.

[0063] S3. Start the drive motor 31, which drives the drive shaft 32 to rotate clockwise. At this time, the drive shaft 32 drives the reciprocating screw 33 to rotate synchronously. When the reciprocating screw 33 rotates, it drives the lifting cylinder 61 to descend synchronously through the lifting collar 62 and the connecting rod 63. As the lifting cylinder 61 continues to descend, the saturated sodium chloride in the second annular liquid storage chamber enters the interior of the lifting cylinder 61 through the top opening of the lifting cylinder 61, and then falls to the top of the organic layer A, thus completing one saturated sodium chloride output.

[0064] S4. Switch the drive direction of the drive motor 31 so that the drive motor 31 drives the drive shaft 32 to rotate counterclockwise. At this time, due to the limitation of the overrunning clutch, the reciprocating screw 33 does not rotate. When the drive motor 31 rotates, it drives the arc-shaped guide plate 42 to rotate through the fixed collar 41. At the same time, the arc-shaped guide plate 42 drives multiple stirring support rods 44 to rotate through the stirring main rod 43, thereby stirring the organic layer A mixed with saturated sodium chloride, thus completing the first washing of the organic layer A.

[0065] S5. Repeatedly switch the drive direction of the drive motor 31 multiple times to complete multiple washes of the organic layer A. At the same time, as the lifting drum 61 continues to descend, when the descent distance of the lifting drum 61 reaches the first threshold, the lifting drum 61 drives the support rod 72 to push the inner annular sleeve 52. The inner annular sleeve 52 drives the threaded sleeve 55 to descend through the outer annular sleeve 54. When the threaded sleeve 55 descends, it drives the stirring main rod 43 to rotate. When the stirring main rod 43 rotates, it drives multiple stirring support rods 44 to rotate around the stirring main rod 43 as the axis, thereby better stirring the organic layer being washed.

[0066] S6. When the lifting cylinder 61 descends to the second threshold, the inner annular sleeve 52 drives the threaded sleeve 55 to descend to the top of the limiting sleeve 45. At this time, the inner annular sleeve 52 can no longer descend. Then, driven by the lifting cylinder 61, the support rod 72 is pushed upward. When the lifting cylinder 61 descends to the third threshold, the bottom of the lifting cylinder 61 contacts the top of the inner annular sleeve 52. The inner annular sleeve 52 closes the bottom opening of the lifting cylinder 61. At the same time, the lifting sleeve 62 moves to the lowest end of the reciprocating thread on the outside of the reciprocating screw 33.

[0067] S7. Subsequently, anhydrous sodium sulfate is manually added to the inside of the washing shell 11 to dry the washed organic layer A. Then, the heating element 17 is activated, and the air inside the washing shell 11 is drawn through the negative pressure pipe 16.

[0072] This invention incorporates a separating mechanism 2, a driving mechanism 3, a stirring and discharging mechanism 4, a triggering mechanism 5, a lifting liquid supply mechanism 6, and a sealing auxiliary mechanism 7. The driving mechanism 3 intermittently drives the lifting liquid supply mechanism 6, thereby causing the separating mechanism 2 to intermittently supply saturated sodium chloride and unsaturated sodium carbonate to the bottom of the washing housing 11 via the lifting liquid supply mechanism 6, rapidly completing the washing of organic layers A and B. Simultaneously, as the lifting liquid supply mechanism 6 is continuously driven, it, through the sealing auxiliary mechanism 7 and the triggering mechanism 5, performs secondary stirring and discharging on the stirring and discharging mechanism 4. The driving mechanism enhances the stirring effect of the stirring and discharging mechanism 4. Simultaneously, as the lifting liquid supply mechanism 6 moves continuously, the sealing auxiliary mechanism 7 is eventually triggered, causing the triggering mechanism 5 to seal the bottom of the lifting liquid supply mechanism 6. This creates a closed environment at the bottom of the inner cavity of the washing shell 11, providing conditions for subsequent vacuum distillation. Compared with similar devices or methods in the prior art, this invention can complete the washing of organic layer A and organic layer B more quickly, and can perform vacuum distillation without transferring the product, thereby significantly improving the preparation efficiency of musk and making it more suitable for industrial production.
