Method for making alkanesulphonyl chlorides

摘要

In the process according to the invention for the manufacture of an alkanesulphonyl chloride RCH2-SO2Cl by oxidative chlorolysis of the corresponding mercaptan RCH2-SH, the mercaptan and water are introduced into the reaction mixture in the form of a dispersion of water in the mercaptan.This makes it possible to obtain both an alkanesulphonyl chloride of very good quality and a hydrochloric acid of commercial grade.
