Abstract: The invention concerns the non-selective catalytic oxychlorination of hydrocarbons, particularly ethylene, by means of hydrogen chloride gas and molecular oxygen. Use is made of catalysts based on silica hydrogel to which there are primarily added magnesium, titanium, copper and an alkali or alkaline earth metal. These catalysts make it possible to produce, for a given combustion rate, a greater amount of superchlorinated hydrocarbons than with previously known catalysts, and can be used in particular for the non-selective oxychlorination of ethylene.
