Abstract
The invention is addressed to the manufacture of chlorinated hydrocarbons by catalytic oxychlorination, in which the chlorine is derived, at least in part, from ammonium chloride, and in which a suitable catalyst comprises a support formed of silica and magnesium with a catalytic active portion formed of copper chloride and an alkali metal chloride. Such catalysts give good yields, little combustion of hydrocarbons and low impurities.
