- Preparation method of trifluoromethyl sulfinyl chloride
-
The invention provides a preparation method of trifluoromethyl sulfinyl chloride. The preparation method comprises the following steps: carrying out a fluorination reaction on a raw material perchloromethyl mercaptan to obtain trifluoromethyl sulfur fluorine, carrying out an oxidation reaction to obtain trifluoromethyl sulfinyl chloride, and carrying out a chlorination reaction to obtain trifluoromethyl sulfinyl chloride. According to the preparation method of trifluoromethyl sulfinyl chloride, a brand-new process route is adopted, the use of the raw material trifluorobromomethane which has a destructive effect on an ozone layer is avoided, and perchloromethyl mercaptan is used as the raw material.
