Abstract

Vapor-phase oxidative acetoxylation of toluene on Pd-based bimetallic catalysts was investigated. The main products were benzylacetate, produced via side-chain acetoxylation, and CO and CO₂ resulted from combustion. Nuclear acetoxylation hardly occurred. A K-doped Pd-Au/SiO₂ gave the highest activity and selectivity for synthesis of benzylacetate among the catalysts tested; the yield of benzylacetate on the K-doped Pd-Au/SiO₂ was about 150 times greater than that on a Pd/SiO₂. It was found that the addition of an adequate amount of Au to Pd/SiO₂ inhibited the formation of CO₂, and that potassium species worked as sites for adsorption and activation of acetic acid.
