Abstract

Methane is oxychlorinated to one or more chlorinated methanes, without net production of carbon tetrachloride, by contacting methane and chlorine and/or hydrogen chloride with a molten mixture of cuprous chloride, cupric chloride, and copper oxychloride, in the presence of an amount of carbon tetrachloride which inhibits net production thereof.
