Abstract—The formation of heterogeneous mercury-, zinc-, and copper-containing catalytic systems obtained
by supporting salt components (SCs) without a solvent is studied. It is shown that due to strong interaction
between SC and support, the size of salt clusters on the surface and their relative contribution decrease. That is,
the concentration of excess salt phases decreases. The dispersity increases up to molecular distribution. When
surface-linked two-dimensional disordered structures are formed, the state of salt phases in the compositions
of catalytic systems changes. The surface mobility of salt clusters during the contact with the reaction medium
is found. Compared to the systems obtained by impregnation with aqueous solutions, the proposed systems are
2–3 times more thermally stable, their surface is enriched in defect structures that are active in catalysis, and
the processes of organochlorine synthesis become more efficient.
