Abstract
1426576 Unsaturated carboxylic acids ROHM GmbH 20 June 1973 [30 June 1972] 29353/73 Heading C2C [Also in Division B1] Alpha, beta-unsaturated carboxylic acids are produced by the oxidative carbonylation of ethylene and/or propylene which comprises reacting ethylene and/or propylene in a substantially anhydrous solvent medium in the presence of a catalyst system comprising, or derived from, at least one solvent-soluble rhenium compound together with at least one solvent-soluble compound of lithium, copper, a metal of Gps. 2 to 6, manganese or iron. Specified reaction conditions include 30‹ to 300‹ C., 10-120 atm. pressure and a stoichiometric ratio of olefin, CO and O 2 . The examples described the carbonylation of (i) ethylene to form acrylic acid together with some propionic acid and beta-acetoxypropionic acid (from which further acrylic acid may be obtained by pyrolysis), (ii) propylene to form crotonic acid together with some methacrylic acid.
