Abstract
Propylene is oxidized directly to allyl acetate in the presence of acetic acid air or oxygen in the liquid phase under moderate reaction conditions employing a palladium-on-carbon catalyst which has been pre-treated be activating it with propylene at temperatures of greater than about 50.degree. C., preferably from 60.degree. to 150.degree. C., for a period of time sufficient to form a small but perceptible quantity of said activated catalyst, preferably for at least 10 minutes in the substantial absence of oxygen.
