X-ray phase analysis and thermal analysis have been used in an investigation of the structure and phase composition of catalytic systems consisting of ZnCl/sub 2/-NaCl and ZnCl/sub 2/-KCl on /gamma/-Al/sub 2/O/sub 3/ support, and also the genesis of these systems under the influence of temperature. It has been shown that the systems contain excess agglomerated salt phases, two-dimensional structures that are cross-linked to the surface, and bulk structures formed by insertion of metal ions into the crystal lattice of the support. At high temperatures, the sodium and potassium chlorides on the surface exist for the most part in isolation from the zinc-containing salt phases. Changes in the composition and structure of the zinc-containing phases play the predominant role in forming the catalytic systems. No melting effects have been found in these catalytic systems.
