Diels-Alder Cyclization over low acidity large-pore zeolites

摘要

The present invention provides a process which is adapted for cyclodimerization of 1,3-butadiene to 4-vinylcyclohexene-1 under Diels-Alder conditions in the presence of a low acidity form of a large-pore zeolite such as ZSM-20, beta or Y.
