Tosyl chloride CAS 98-59-9
Tosyl chloride CAS 98-59-9
Tosyl chloride(TsCl), as a fine chemical product, is widely used in the dye, pharmaceutical, and pesticide industries. In the dye industry, it is mainly used to manufacture intermediates for disperse, ice dye, and acid dyes; in the pharmaceutical industry, Chemicalbook is mainly used to produce sulfonamides, mesulfonate, etc.; in the pesticide industry, it is mainly used in the production of mesotrione, sulfotrione , fine metalaxyl, etc. With the continuous development of the dye, pharmaceutical and pesticide industries, the international demand for this product is growing day by day.
There are two main traditional processes for TsCl: 1. It is produced by direct acid chlorination of toluene and excess chlorosulfonic acid at low temperature. This method produces o-toluenesulfonyl chloride with high content, and p-toluenesulfonyl chloride is its by-product, and both It is difficult to separate and consumes a lot of energy; 2. Toluene and chlorosulfonic acid are directly chlorinated with excess chlorosulfonic acid in the presence of certain salts and at a certain temperature. Although this method has a higher product ratio of toluenesulfonyl chloride, the purification ratio The method is easy and consumes low energy. However, due to the relatively high reaction temperature, the separated sulfonated oil contains high sulfones and has low utilization value. The actual total yield is only about 70% in Chemicalbook. In addition, both methods have high consumption of raw material chlorosulfonic acid and the waste sulfuric acid produced is too dilute, which is not conducive to industrial utilization and treatment. There are also reports to improve the method. First, the p-toluenesulfonyl chloride in the reaction mixture is fully crystallized under certain conditions and the crystal particles are enlarged. The method of direct filtration without hydrolysis is used to remove the p-toluenesulfonyl chloride from the mixture. However, there are currently certain difficulties in selecting industrial equipment and the investment is large. Improved process: Suitable catalysts and other optimal process conditions were selected.
Tosyl chloride (TsCl) is a white flaky crystal with a melting point of 69-71°C. It is an important organic synthesis drug intermediate and is mainly used in the synthesis of chloramphenicol, chloramphenicol-T, thiamphenicol and other drugs. .
