Abstract

319,030. Dreyfus, H. March 16, 1928. Acetic acid; methyl acetate.-Acetic acid is obtained, in the free state or as methyl ester, by the reaction of dimethyl ether and carbon monoxide in the presence of alkali alcoholates or alkali formates as catalysts, or in the absence of catalysts. Temperatures of 200-450‹ C. and pressures of 50-300 atmospheres are preferably employed. If sufficient water vapour is present in the reaction mixture, acetic acid preponderates in the product, while in the presence of little or no water methyl acetate is the main product. The methyl acetate may be saponified to acetic acid by the processes described in Specifications 283,989 and 284,582, and the dimethyl ether resulting mav be returned to the main process. Propionic acid, ethyl propionate, and other aliphatic acids and esters may be prepared similarly from the corresponding ethers.
