Abstract

The new 1-monochloro- and 1,1-dichloro-prop-2,3-ene-3-sulfonic acids and their metal salts, and a process for their manufacture by reacting chloropropanesulfonic acid compounds with alkali metal carbonates, alkali metal bicarbonates and/or alkaline earth metal hydroxides at from 5.degree. to 100.degree. C to give 1-chloro-prop-2,3-ene-3-sulfonates which may then be reacted with acid compounds in a second step. The products are starting materials for the manufacture of pesticides, plasticizers, solvents, leather greases, detergents, lubricating oils, synthetic resins and slip agents. They are also assistants in electroplating processes and starting materials for the manufacture of such assistants.
