Popis:	A supported liquid phase catalyst consisting of a copper chloride/potassium chloride mixture with or without cerium chloride and supported on either alumina or titania has been investigated using X-ray diffraction and transmission electron microscopy both with and without a heating stage. Catalysts used in an oxychlorination experiment have also been examined. X-Ray and TEM studies confirmed the existence of small clusters of active phase which were mobile at high temperatures and could coalesce to a greater or lesser extent depending upon the addition of cerium chloride. The X-ray studies also indicated the presence of a K 2 CuCl 4 · 2H 2 O phase in the used catalyst.
