Abstract

1,267,225. Diacyloxyalkenes. FARBENFABRIKEN BAYER A.G. 4 Aug., 1970 [19 Aug., 1969; 29 Jan., 1970], No. 37520/70. Heading C2C. 1,3-Diacetoxy-2-methylene propane is prepared by passing isobutene, oxygen and acetic acid in the gas phase over a palladium-containing catalyst at 50‹ to 250‹ C. and at least some of the constituents boiling at temperatures above 150‹ C. at normal pressure, are removed from the reaction product whilst at least some of the constituents boiling at temperatures below 150‹ C. at normal pressure are recycled to the reaction. The catalyst may also contain at least one alkali metal acetate or alkali metal compound which under the reaction conditions is converted at least partly into an alkali metal acetate, and at least one metal or metal compound from the Vth to the VIIIth Group of the Periodic System and/or of gold and/or of copper, preferably an iron compound.
