Problems solved by technology

[0005] The object of the present invention is to aim at the deficiencies of the prior art, by setting a drive mechanism to drive the uniform dripping mechanism, the uniform dripping mechanism can complete the intermittent dripping work of water on the one hand, and evenly fall in the process of moving down; on the other hand, it can change in real time The air pressure under the uniform dripping mechanism increases gradually while the temperature of the reaction space drops slowly, so that the water in the range of 70°C to 50°C can ensure the completion of dripping, thus solving the need for water in the process of hydrolysis reaction. When the reaction kettle drops from 70°C to 50°C, all the dripping work is completed, but there are impurities in the reaction kettle, and the reaction temperature is difficult to control.

Abstract

The invention relates to a processing device for preparing p-toluenesulfonyl chloride, which includes a reaction kettle, a cleaning mechanism, a uniform dripping mechanism, a stirring mechanism and a gasoline transmission mechanism; the uniform dripping mechanism includes a water container, a first connecting pipe, and a control assembly And the pressure regulating assembly, the pressure regulating assembly is driven by the driving mechanism to move up and down in the vertical direction; the stirring mechanism includes the stirring assembly, the first transmission assembly and the driving assembly; the cleaning mechanism includes the cleaning assembly and the collecting assembly; the gasoline transmission mechanism includes the oil container and The second transmission component; the present invention solves the technical problem that in the process of hydrolysis reaction, water needs to be dropped from 70°C to 50°C in the reaction kettle to complete all the dripping work, but there are impurities in the reaction kettle and the reaction temperature is difficult to control.

Description

technical field [0001] The invention relates to the technical field of organic grease, in particular to a processing device for preparing p-toluenesulfonyl chloride. Background technique [0002] As a fine chemical product, p-toluenesulfonyl chloride is widely used in the dyestuff, medicine, and pesticide industries. In the dyestuff industry, it is mainly used to manufacture disperse, ice dyeing, and acid dye intermediates; in the pharmaceutical industry, it is mainly used to produce sulfonamides. Drugs - mesotrione, etc.; the pesticide industry is mainly used for mesotrione, sulcotrione, mefenaxyl, etc. With the continuous development of dyestuffs, pharmaceuticals, and pesticide industries, the international demand for this product is increasing Growth, especially in Europe and the United States, has broad market prospects. [0003] The patent document with the patent number CN2015209956449 discloses a refining system for the crude product of p-toluenesulfonyl chloride, in...
