ISOMERIZATION OF DIACYLOXYBUTENES

摘要

The invention relates to a process for converting diacyloxybutenes into one another in the gas phase or liquid phase at from 100 to 350.degree.C under atmospheric or superatmospheric pressure in the presence of a catalyst, wherein a 1,4-diacyloxybut-2-ene of the formula (I): (I) and a 3,4-diacyloxybut-1-ene of the formula (II): (II) where R1 and R2 can be identical or different and are each hydrogen or alkyl of 1 to 3 carbon atoms, and R3 and R4 can be identical or different and are each hydrogen or methyl, are converted into one another in the presence of a zeolite as a catalyst.
