Abstract
Abstract A method of producing allylacetate residing in that propylene is reacted with acetic acid and oxygen in a gaseous phase at a temperature of 150°-250° C under a pressure of 1-10 atg in the presence of a catalyst containing tetraammonium palladium acetate of the formula / Pd(NH 3 ) 4 / (CH 3 COO) 2 and activators on a support. The proposed invention makes it possible to increase the yield of allylacetate per liter of the catalyst per hour.
