Abstract

1. Process for the manufacture of methylene chloride by the chlorination of methyl chloride in the liquid phase, in the presence of a free-radical initiator, characterised in that the reaction is carried out substantially in the absence of chlorine gas and in the presence of a free-radical initiator chosen from amongst peroxide compounds and diazo compounds.
