ABSTRACT:
A process of contacting a feedstream containing dioxygen, carbon monoxide, ether, and alkanol, which can be vaporized under conditions of reaction, with a blend of catalysts which are heterogeneous to the feedstream, under conditions of reaction sufficient to form a mixture containing at least one higher molecular weight oxygenated organic compound is described. In another aspect, this invention relates to a blend of catalysts consisting of at least one molecular sieve, natural or synthetic, which has been found useful for hydrocarbon conversion reactions and a catalyst comprising a metal halide or a mixed metal halide supported on active carbon, which is effective in catalyzing direct formation of organic carbonates.
