Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature control technology for the preparation of triphenylchloromethane, and more specifically, to a temperature control device for the preparation of triphenylchloromethane. Background Technology
[0002] Triphenylchloromethane is an organic compound, a white crystalline solid, insoluble in water but readily soluble in benzene, carbon disulfide, petroleum ether, and n-hexane, and slightly soluble in alcohols and ethers. In organic synthesis, triphenylchloromethane serves as an important pharmaceutical intermediate and chemical reagent, commonly used for the introduction of protecting groups and peptide synthesis. Distillation is a crucial step in the preparation of triphenylchloromethane. Currently, the commonly used distillation method involves heating the distillation flask with an alcohol lamp to separate raw materials with different boiling points. However, this heating method cannot provide uniform heating of the distillation flask, and the temperature is uncontrollable. Furthermore, once the temperature rises above the optimal range, it cannot be cooled down quickly, resulting in poor distillation efficiency. Therefore, we propose a temperature control device for the preparation of triphenylchloromethane. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a temperature control device for the preparation of triphenylchloromethane, including a distillation chamber. The distillation chamber includes a shell, and a heating assembly is disposed inside the shell. The heating assembly includes a bottom chamber, which is fixedly disposed at the bottom of the shell. A circuit breaker assembly is disposed inside the bottom chamber, and the circuit breaker assembly includes a current receiving block. A transmission rod is disposed on one side of the current receiving block, and one end of the transmission rod is slidably disposed inside the current receiving block.

A current output block is disposed at the end of the transmission rod away from the current receiving block, and the current output block is fixedly disposed inside the bottom chamber. One end of the transmission rod is slidably disposed inside the current output block.
[0005] As a further improvement to this technical solution, a current receiving plate corresponding to the position of the transmission rod is slidably arranged inside the current output block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] In this temperature control device for the preparation of triphenylchloromethane, when the internal temperature of the shell is too high, the transmission rod is pushed to one side by the second push plate, and at the same time, the pressure spring pushes the current receiving plate away from the transmission rod. As the transmission rod and the current receiving plate are disconnected, the cooling fan transports the hot air inside the shell to the outside, so that the solution inside the shell is cooled down quickly. The device automatically stops heating the shell when the internal temperature is too high, and at the same time lowers the internal temperature of the shell to a suitable range, preventing the raw material from being separated incompletely due to the excessive internal temperature of the shell, which would affect the distillation effect and improve the practicality of the device.

[0025] Example 1
[0026] Please see Figures 2-5As shown, this embodiment provides a temperature control device for the preparation of triphenylchloromethane, including a distillation chamber 1. The distillation chamber 1 includes a shell 11, and a base 12 is fixedly disposed inside the shell 11. A fixing ring 13 is symmetrically disposed on the upper side of the base 12. A push rod 14 is symmetrically fixed between the fixing ring 13 and the inner wall of the shell 11. A driver 15 is disposed on the lower side of the push rod 14 and is fixedly disposed inside the shell 11. A distillation flask 4 is disposed on the upper side of the base 12. The distillation flask 4 includes a shell 41, which is disposed between the base 12 and the fixing ring 13. A distillation tube 42 is fixedly disposed on the upper side of the shell 41. A stirrer 43 is rotatably disposed inside the shell 41. One end of the rotating shaft of the stirrer 43 is disposed on the outer side of the shell 41, and a slot corresponding to the driver 15 is opened at one end of the rotating shaft of the stirrer 43. When using this device, the user first adds the liquid to be distilled into the shell 41, then places the shell 41 on the upper side of the base 12, and then... The control push rod 14 pushes the fixing ring 13 towards the side closer to the outer shell 41. The two fixing rings 13 fix the outer shell 41 inside the shell 11. Then, the user connects one end of the driver 15 to the rotating shaft of the stirrer 43 and inserts it into the corresponding slot. The heating component 2 is provided inside the shell 11. The heating component 2 includes a bottom chamber 21, which is fixedly set at the bottom of the shell 11. A heat insulation plate 22 is fixedly set on the upper side of the bottom chamber 21. A heating plate 23 is set on the upper side of the heat insulation plate 22. An electric heating wire 24 is fixedly set on the upper side of the heating plate 23. A heating chamber 25 is fixedly set on the upper side of the heat insulation plate 22. Both the heat insulation plate 22 and the heating plate 23 are fixedly set inside the heating chamber 25. After the outer shell 41 is fixed, the user heats the bottom of the outer shell 41 by connecting the power supply of the heating component 2. At the same time, the user starts the driver 15 to drive the stirrer 43 to rotate, continuously stirring the liquid inside the outer shell 41 to make it evenly heated, so as to accelerate its evaporation rate.
[0027] Please see Figures 1-4As shown, a control panel 6 is fixedly installed on one side of the housing 11. The user can adjust the temperature of the heating component 2 by operating the control panel 6 and observe the real-time temperature inside the housing 41 through the control panel 6. A circuit breaker component 3 is installed inside the bottom compartment 21. The circuit breaker component 3 includes a current receiving block 31. A transmission rod 32 is installed on one side of the current receiving block 31. A current output block 35 is installed at the end of the transmission rod 32 away from the current receiving block 31. The current output block 35 is fixedly installed inside the bottom compartment 21. One end of the transmission rod 32 is slidably installed inside the current receiving block 31. A pad 33 is installed on the lower side of the transmission rod 32. A pad 33 is fixedly installed inside the bottom compartment 21. A push plate 34 is slidably installed between the pad 33 and the current receiving block 31. The push plate 34 is fixedly installed on the lower side of the transmission rod 32. A spring is fixedly installed between the push plate 34 and the current receiving block 31. One end of the transmission rod 32 is slidably installed inside the current output block 35. A current receiving piece 36 corresponding to the position of the transmission rod 32 is slidably installed inside the current output block 35. Pressure springs 37 are symmetrically fixed between the current receiving piece 36 and the inner wall of the current output block 35. A second spring is slidably installed between the current output block 35 and the pad 33. Push plate 39, the second push plate 39 is fixedly installed on the lower side of transmission rod 32. A telescopic rod is fixedly installed between the second push plate 39 and the current output block 35. A signal receiver 38 is fixedly installed on one side of the current output block 35. When the internal temperature of the outer casing 41 exceeds the normal range, the control panel 6 immediately transmits information to the signal receiver 38. Then, the signal receiver 38 controls the telescopic rod on one side of the second push plate 39 to push the second push plate 39. At the same time, two pressure springs 37 push the current receiving piece 36 away from the transmission rod 32, so that the current receiving piece 36 is disconnected from the transmission rod 32. At the same time, the heating wire 24 immediately... Heat generation stops. A cooling fan 5 is fixedly installed on one side of the housing 11. The cooling fan 5 is located inside the housing 11. A heat dissipation hole is opened on the side of the housing 11 away from the cooling fan 5. When the current receiving piece 36 is disconnected from the transmission rod 32, the cooling fan 5 transports the heat flow inside the housing 11 to the outside of the housing 11, causing the temperature inside the outer shell 41 to drop rapidly. When the temperature inside the outer shell 41 drops to the normal range, the telescopic rod on one side of the second push plate 39 begins to retract. At the same time, the spring on one side of the first push plate 34 pushes the first push plate 34, causing the transmission rod 32 to reconnect with the current receiving piece 36.
[0028] In this embodiment of the temperature control device for the preparation of triphenylchloromethane, the user first fixes the outer shell 41 with two fixing rings 13. When the internal temperature of the outer shell 41 is too high, the user controls the second push plate 39 to push the transmission rod 32 to one side. At the same time, the pressure spring 37 pushes the current receiving plate 36 away from the transmission rod 32. When the transmission rod 32 and the current receiving plate 36 are disconnected, the cooling fan 5 delivers the hot air inside the shell 11 to the outside, so that the solution inside the outer shell 41 is cooled down quickly. The device automatically stops heating the outer shell 41 when the internal temperature of the outer shell 41 is too high, and at the same time lowers the internal temperature of the outer shell 41 to a suitable range, preventing the raw material separation from being incomplete due to the excessive internal temperature of the outer shell 41, which would affect the distillation effect and improve the practicality of the device.
