X-ray phase analysis, thermal analysis, and diffuse reflection electronic spectroscopy have been used in studying the formation of the catalytic system ZnCl/sub 2///gamma/-Al/sub 2/O/sub 3/. It has been shown that interaction of the salt component with the support leads to the formation of a complex multiphase system including excess zinc-containing phases with various compositions, structures cross-linked to the surface, and spinel-type structures formed by insertion of zinc ions into the surface layers of the lattice of the support. The kinds of phases that result from this interaction depend on the conditions of catalyst formation and on the phase composition of the support. The catalytic system does not contain and compositions that are fusible within the interval of temperatures investigated (20-500/degree/C).
