Abstract
Procedure for the preparation of diacyloxyalkenes, characterized in that an acyloxyalkene of the formula is reacted **(See formula)** where n is 0 or 1 and R represents one of the -CH2 groups; -CH2-CH2- or (see formula), with acetic acid, propionic acid or isobutyric acid and molecular oxygen in the gas phase, possibly in the presence of inert gases, at temperatures from 100 to 250ºC, preferably from 150 to 220ºC, and at pressures of 1 to 20 absolute atmospheres, preferably from 5 to 10 absolute atmospheres, in the presence of supported catalysts containing palladium metal, a support substance and optionally activators.
