Abstract
1,264,377. Acyloxylation of olefins. HALCON INTERNATIONAL Inc. 4 July, 1969 [5 July, 1968], No. 33785/69. Heading C2C. A continuous process for the production of acyloxylated olefins comprises (a) contacting a gaseous reaction mixture containing molecular oxygen, olefin to be acyloxylated and carboxylic acid with a first body of catalyst, said contacting being carried out at a temperature within the range of from 50 to 350‹ C. at a space velocity from 20 to 5000 hours<SP>-1</SP> whereby a conversion of olefin within the range of from 4% to 20% is obtained; (b) removing acyloxylated olefin from the resulting mixture; (c) purging a portion of the remaining mixture; (d) recycling the portion of the mixture remaining after purging for further contact with said first catalyst; (e) contacting the purged gaseous mixture with a second body of catalyst, said contacting being carried out at a temperature in the range of from 50‹ to 350‹ C. at a space velocity from 20 to 5000 hours<SP>-1</SP>; and (f) recovering additional acyloxylated olefin, both said first and second bodies of catalyst comprising a Group VIII metal having an atomic number of at least 44.
