CATALYST FOR HYDROXYCHLORINATION OF ETHYLENE INTO 1,2-DICHLOROETHANE AND METHOD OF PREPARATION THEREOF Russian patent published in 1998 - IPC

FIELD: catalyst production. SUBSTANCE: catalyst is composed of copper compound (3.5-5.5 wt %) on a metal- containing alumina carrier. The latter constitutes a solid solution of Me²⁺ and/or Me³⁺ metal ions in aluminum oxide at Al³⁺/Me²⁺ and/or Al³⁺/Me³⁺ ratio ranging from 200:1 to 20:1. As Me²⁺ and/or Me³⁺ following ions are used: Ce³⁺, Ca³⁺, Mg²⁺, Mn²⁺, Cu²⁺,, and, as copper compounds, water-soluble ones. Catalyst is prepared by applying copper compound onto above-indicated solid solution involving spraying of copper compound solution and heat treatment under conditions providing complete crystallization of the active component for less than 30 min. EFFECT: increased catalyst activity resulting in increased conversion into dichloroethane. 5 cl, 1 tbl
