Claims
- 1. A process for the preparation of benzyl esters which comprises reacting toluene with a carboxylic acid and oxygen in the liquid phase in the presence of a catalytically effective amount of a supported catalyst consisting essentially of palladium metal, gold metal and a metal of Group VA of the Periodic Table of Elements.
- 2. A process for the preparation of benzyl acetate which comprises reacting toluene, acetic acid and oxygen in the liquid phase in the presence of a catalytically effective amount of a supported catalyst consisting essentially of palladium metal, gold metal and a metal of Group VA of the Periodic Table of Elements.
- 3. The process of claim 2 wherein the Group VA metal is bismuth.
- 4. The process of claim 2 wherein the reaction takes place at a temperature of from about 100.degree. C. to about 300.degree. C. and at a pressure of from about 10 to 2500 psig.
- 5. The process of claim 2 wherein the palladium to gold weight ratio is from about 0.5:1 to 2:1 and the Group VA metal is present in an amount by weight equal to or greater than the weight of palladium.
- 6. The process of claim 2 wherein the total amount of catalyst deposited upon the support is from about 0.1 to 20% by weight of the support.
- 7. A process for the preparation of benzyl acetate which comprises reacting toluene, acetic acid and oxygen in the liquid phase in the presence of a catalytically effective amount of a supported catalyst consisting essentially of palladium metal, gold metal, a metal of Group VA of the Periodic Table of Elements and a promoter selected from the group consisting of zinc acetate, lead acetate, copper acetate, the acetates of alkali and alkaline earth metals, bismuth subcarbonate, tellurium oxide and mixtures thereof.
- 8. The process of claim 7 wherein the promoter is a member of the group consisting of copper acetate and bismuth subcarbonate and the Group VA metal is bismuth.
