Abstract: 1,4-diacyloxybutenes are prepared by reacting a 1,3-butadiene with a carboxylic acid and oxygen in the presence of a catalyst in a reactor, by a process in which the 3,4-diacyloxybutene formed as a by-product in the reaction is separated off from the reaction mixture, and some or all of this 3,4-diacyloxybutene is recycled to the reactor.

Abstract: Process for the preparation of diacyloxybutenes by reacting optionally substituted 1,3-butadiene with carboxylic acids and oxygen on a palladium- or platinum-containing catalyst in a reactor, where, in addition to the starting materials, alkanes or alkenes having one double bond, each of which contains 3 to 5 C atoms, are introduced and the alkanes or alkenes in gaseous form are recovered from the liquid reaction mixture after it has left the reactor and returned into the reactor in liquid form.
