CATALYST, METHOD OF PREPARATION THEREOF AND ITS USE IN 1,2-DICHLOROETHANE SYNTHESIS Russian patent published in 2003 - IPC

FIELD: organic synthesis catalysts. SUBSTANCE: invention provides catalyst for use, in particular, in synthesis of 1,2-dichloroethane via oxychlorination of ethylene in fluidized-bed or fixed-bed reactor. Catalyst is prepared by impregnation of gamma-alumina with magnesium salt, drying of impregnated product, and impregnation with copper salt, preferably with lithium salt. Catalyst contains 0.1-5% magnesium , 2-10% copper, and up to 5% lithium and is especially effective in oxygen-based processes. EFFECT: increased productivity of catalyst. 7 cl, 1 dwg, 5 tbl, 10 ex
