PROCESS FOR PRODUCING ETHYLIDENE DIACETATE AND/OR ACETALDEHYDE

摘要

A process for producing ethylidene diacetate and/or acetaldehyde which comprises causing hydrocarbonylation reaction of methyl acetate or dimethyl ether with carbon monoxide and hydrogen in the presence of a catalyst consisting essentially of (i) as a main component palladium supported on a porous inorganic material and (ii) as a secondary component at least one halide selected from the group consisting of iodides, bromides and mixtures thereof under substantially anhydrous condition is disclosed.
