What is Tosyl chloride?

  1. As a fine chemical product, Tosyl chloride is widely used in dye, medicine, and pesticide industries. In the dye industry, it is mainly used in the manufacture of intermediates for dispersion, ice dyeing and acid dyes; in the pharmaceutical industry, it is mainly used in the production of sulfa drugs, mesotrione, etc.; in the pesticide industry, it is mainly used in mesotrione and sulcotrione , Metalaxyl and so on. With the continuous development of the dye, medicine, and pesticide industries, the international demand for this product is increasing, especially in Europe and the United States, and the market prospects are broad.
  2. Tosyl chloride synthesis method: toluene and excess chlorosulfonic acid are directly chlorinated at low temperature. This method produces high content of o-toluenesulfonyl chloride, and p-toluenesulfonyl chloride is a by-product, and the two are difficult to separate and consume large amounts of energy.
  3. Tosyl chloride synthesis method: Toluene and chlorosulfonic acid are directly prepared by chlorination with excess chlorosulfonic acid in the presence of certain salts and at a certain temperature. Although this method has a higher proportion of tosyl chloride, it is easier to purify than the method. The consumption is low, but due to the relatively high reaction temperature, the separated sulfonated oil contains high sulfones and low utilization value. The actual total yield is only about 70%.

Tosyl chloride Uses

  1. Tosyl chloride is an intermediate of disperse dyes, ice dyes and acid dyes. It is also used in the production of the drug metsulfuron.
  2. Tosyl chloride is used as an analytical reagent and also used in molecular rearrangement reactions in organic synthesis, dye preparation and hormone synthesis.
  3. Tosyl chloride is used in organic synthesis, sulfa drugs and pesticide intermediates.
