CATALYST AND METHOD OF PRODUCING VINYL ACETATE FROM ACETIC ACID AND ACETYLENE

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to chemical catalysts for synthesis of vinyl acetate. Described is a catalyst for synthesis of vinyl acetate from acetic acid and acetylene, which contains zinc acetate and a support, wherein the support is Sibunit carbon consisting of microspherical nanoporous particles with size of 200-500 mcm. Described is a method of producing vinyl acetate from acetic acid and acetylene in the presence of the catalyst described above, characterised by that the method is realised at temperature 170-220C, volume flow rate of acetylene of 0.54-0.84 l/cm3 (cat)çh, mass flow rate of acetic acid of 0.3-0.5 g/cm3 (cat)çh. ^ EFFECT: described is a catalyst characterised by high mechanical strength and catalytic activity and long service life. ^ 7 cl, 2 tbl, 17 ex
