ABSTRACT:
An oxychlorination catalyst which is an intimate mixture of the oxides of magnesium, aluminum and copper obtained by calcining is prepared by precipitating the hydrated oxides of magnesium and aluminum, drying and calcining these hydrated oxides to form a mixed oxide of magnesium and aluminum, treating the mixed oxide with a copper salt solution and again calcining to provide the copper oxide.
