Abstract

An improved process has been invented for the production of (1-chloroethenyl)-oxirane which comprises dehydrochlorinating (1,2-dichloroethyl)-oxirane with a solution of the sodium salt of an alcohol having at least 5 carbon atoms in said alcohol and separating the (1-chloro-ethenyl)-oxirane from the reaction mixture.
