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.
