Abstract
1,244,262. Methacrylic acid esters. IDEMITSU KOSAN CO. Ltd. 29 Oct., 1969 [29 Oct., 1968], No. 52929/69. Heading C2C. Methacrylic acid esters are prepared by reacting a mixture of methylacetylene and allene, carbon monoxide and an alcohol in the presence of nickel carbonyl and an organic carb - oxylic acid as a catalyst. The methylacetylene/ allene mixture is obtained by the pyrolysis of propylene. An inert diluent may be present, and the organic carboxylic acids may be methacrylic and crotonic acids, and in a modification the acids. are formed by the presence of water. Elevated temperatures 100-200‹ C. and pressures 10-60 atmospheres are preferred and the process may be continuous. Crotonates, e.g. methyl, are produced as by-products.
