METHOD OF PREPARING METHYL ACETATE, AND CATALYSTS FOR CARRYING IT THROUGH Russian patent published in 2001 - IPC

Abstract RU 2170724 C1

FIELD: chemical industry. SUBSTANCE: method comprises carbonylation of dimethyl ether in gas phase at elevated pressure at temperature from 200 to 250 C in the presence of catalyst. Catalyst is acid cesium salt of phosphorus-tungsten heteroacid composed of Cs_xH_yPW₁₂O₄₀, wherein 1,5 ≅ x ≅ 2, y = 3-x, with rhodium additives in amount from 0.1 to 2.5 wt %. EFFECT: increased yield of methyl acetate in reaction of carbonylated dimethyl ether without using halogencontaining promoters. 4 cl, 5 ex, 1 tbl
