Abstract
A process for producing an allyl carboxylate comprising the step of reacting propylene, oxygen or oxygen-containing gas, and a lower saturated carboxylic acid in the presence of a catalyst at a temperature of 100.degree. C. to 300.degree. C. and a pressure of 0 to 30 atm (gauge) in a vapor phase. The catalyst is prepared by supporting, on a carrier, at least one alkali metal acetate and at least one bivalent palladium salt in the presence of: (A) at least one organic base selected from the group consisting of (i) aliphatic amines having the formula: ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 may be the same or different and represent hydrogen, or an alkyl group having 1 to 10 carbon atoms or benzyl group optionally substituted with --CN, --OR, --COOR, or a --N(R).sub.2 group wherein R is H or an alkyl group having 1 to 3 carbon atoms, or any two groups of R.sup.1, R.sup.2, and R.sup.3 may together form a ring provided that R.sup.1, R.sup.2, and R.sup.3 are not simultaneously hydrogen; (ii) aromatic amines having the formula: ##STR2## wherein X represent --R, --CN, --OR, --COOR, --NO.sub.2, or --N(R).sub.2 wherein R is the same as defined above, R.sup.2 and R.sup.3 are the same as defined above; and (iii) nitrogen-containing cyclic compounds having the formula: ##STR3## wherein X is the same as defined above; and/or (B) at least one carboxylic acid having the formula:
