Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically a dimethyl disulfide reaction vessel with constant temperature in a water bath. Background Technology
[0002] Dimethyl disulfide is used in the synthesis of the organophosphorus insecticide phosmet, and also in the synthesis of p-methylthiophenol, an intermediate for chlorpyrifos, and p-methylthiophenol, an intermediate for thiopropionate. It can also be used as a solvent and a purifying agent for catalysts. Dimethyl disulfide is obtained by reacting dimethyl sulfate with sodium disulfide. The specific preparation process involves adding sulfur powder to a sodium disulfide solution under stirring, heating to 80-90°C, reacting for a certain time, cooling to about 30°C, then adding dimethyl sulfate dropwise into the reaction vessel, continuing the reaction for 2 hours, then distilling, allowing the mixture to stand and separate into layers, separating the waste alkaline solution, and then distilling again to obtain the final product.
[0003] For example, the water bath constant temperature dimethyl disulfide reactor disclosed in patent announcement number CN 216936026 U, although it realizes a water bath constant temperature dimethyl disulfide reactor including a reactor body, a constant temperature water bath pot set outside the reactor body, the reactor body located in the constant temperature water bath pot, the constant temperature water bath pot providing constant temperature heat to the reactor body, and the reactor body providing preparation space for the preparation of dimethyl disulfide, does not solve the problem that in the past water bath constant temperature dimethyl disulfide reactors, due to the lack of a component that can detect the water temperature and a component that can automatically collect dimethyl disulfide, the water bath constant temperature may not be up to standard, the reaction may be incomplete, and the dimethyl disulfide cannot be collected efficiently. Utility Model Content
[0004] The purpose of this invention is to provide a water bath constant temperature dimethyl disulfide reactor to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dimethyl disulfide reactor with constant temperature water bath includes a constant temperature water bath mechanism. The constant temperature water bath mechanism includes a water bath shell, an internal water bath cavity, a bottom constant temperature heating module, and a temperature detection module. The constant temperature water bath mechanism includes a water bath shell, and the internal water bath cavity is fixedly disposed inside the water bath shell. The bottom constant temperature heating module is fixedly disposed at the bottom of the internal water bath cavity. The water bath shell includes a temperature detection module.
[0007] The internal water bath chamber is equipped with a reaction vessel mechanism, which includes a reaction vessel body, an upper mixing top cover, a middle distillation layer, a bottom mixing shell, and a mixing chamber. The reaction vessel body includes an upper mixing top cover, a middle distillation layer is fixedly installed at the bottom of the upper mixing top cover, a bottom mixing shell is fixedly installed at the bottom of the middle distillation layer, and a mixing chamber is located inside the bottom mixing shell.
[0008] Preferably, the temperature detection module includes a display screen, and a data transmission temperature measuring tube is fixedly installed at the bottom of the display screen. The advantage is that the water inside the internal water bath is measured by the data transmission temperature measuring tube to maintain the water temperature at a suitable temperature to improve the reaction efficiency.
[0009] Preferably, the upper mixing cover includes a feed pipe, which has the advantage that the materials to be reacted can be effectively transported into the mixing chamber for reaction through the feed pipes at both ends.
[0010] Preferably, the upper mixing cover includes a drive motor, and a mixing rod is movably disposed at the bottom of the drive motor. The advantage is that the mixing rod is driven to rotate by the drive motor, so that the internal materials are fully mixed and the reaction efficiency is improved in conjunction with the constant temperature water bath mechanism.
[0011] Preferably, a flow control valve is fixedly installed at the bottom of the middle distillation layer, and a collection pipe is fixedly installed at the bottom of the flow control valve. The advantage is that the collection pipe can effectively control the flow of dimethyl disulfide that has completed distillation through the flow control valve, and collect it through the collection pipe to the collection bucket at the bottom, which effectively improves the working efficiency of the device.
[0012] Preferably, a collection bucket is fixedly provided at the bottom of the collection pipe. The advantage is that it can effectively collect dimethyl disulfide into the bucket, effectively prevent dimethyl disulfide from being contaminated when exposed to air, and effectively reduce the work steps of operators.
[0013] Preferably, the water bath housing includes a water inlet pipe, which has the advantage of effectively ensuring sufficient moisture inside the internal water bath chamber.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This water bath constant temperature dimethyl disulfide reactor first heats the water in the internal water bath chamber through the bottom constant temperature heating module. After heating, the required materials are transported to the mixing chamber at the bottom through the feed pipe. Then, the mixing rod inside the mixing top cover is driven by a drive motor to rotate, which fully mixes the materials and, together with the constant temperature water bath mechanism, improves the reaction efficiency. During the reaction, the temperature of the water in the internal water bath chamber is measured by a data transmission temperature measuring tube. The temperature data is then processed and displayed on the screen for operators to observe. After the reaction is completed, distillation is performed to remove internal impurities. The distilled dimethyl disulfide will remain in the middle distillation layer. The flow rate is controlled by the flow control valve at the bottom and the dimethyl disulfide is collected into the collection tank through the collection pipe, completing the process.
[0016] The advantages of this water bath constant temperature dimethyl disulfide reactor are that, in the past, the lack of components for detecting water temperature and automatically collecting dimethyl disulfide led to problems such as insufficient reaction due to substandard water bath temperature and inefficient collection of dimethyl disulfide. This new water bath constant temperature dimethyl disulfide reactor solves these problems by using a temperature detection module to monitor the internal water temperature in real time and a collection tank to effectively collect dimethyl disulfide.

[0027] In this embodiment, preferably, the temperature detection module 4 includes a display screen 10, and a data transmission temperature measuring tube 11 is fixedly installed at the bottom of the display screen 10. The advantage is that the water inside the internal water bath 2 is measured by the data transmission temperature measuring tube 11 so as to keep the water temperature at a suitable temperature to improve the reaction efficiency.
[0028] In this embodiment, preferably, the upper mixing top cover 6 includes a feed pipe 12. The advantage is that the feed pipes 12 at both ends can effectively transport the material to be reacted into the mixing chamber 9 for reaction.
[0029] In this embodiment, preferably, the upper mixing top cover 6 includes a drive motor 13, and a mixing rod 14 is movably disposed at the bottom of the drive motor 13. The advantage is that the mixing rod 14 is driven to rotate by the drive motor 13, so that the internal materials are fully mixed and the constant temperature water bath mechanism is used to improve the reaction efficiency.
[0030] In this embodiment, preferably, a flow control valve 15 is fixedly installed at the bottom of the middle distillation layer 7, and a collection pipe 16 is fixedly installed at the bottom of the flow control valve 15. The advantage is that the collection pipe 16 can effectively control the flow of dimethyl disulfide that has completed distillation through the flow control valve 15, and collect it through the collection pipe 16 to the collection bucket 17 at the bottom, which effectively improves the working efficiency of the device.
[0031] In this embodiment, preferably, a collection bucket 17 is fixedly provided at the bottom end of the collection pipe 16.

[0033] In this embodiment, a water bath constant-temperature dimethyl disulfide reactor is used.

The dimethyl disulfide that remains in the middle distillation layer 7 is controlled by the flow control valve 15 at the bottom and then collected into the collection tank 17 through the collection pipe 16 to complete the work. The advantage is that in the previous water bath constant temperature dimethyl disulfide reactor, the lack of a component that can detect the water temperature and an automatic component that can collect dimethyl disulfide during use may lead to problems such as the water bath constant temperature not being up to standard, incomplete reaction, and inefficient collection of dimethyl disulfide. Therefore, a water bath constant temperature dimethyl disulfide reactor has been proposed to solve the above problems.
