Process for the selective dimerisation of isobutene

摘要

The present invention relates to processes for making a reaction product comprising trimethylpentene(s) which comprises contacting C4 olefinic feedstock containing isobutene and n-butene(s) with a catalyst comprising zeolite beta under conditions allowing selective dimerization of isobutene to trimethylpentene(s). It also relates to the products obtained by these processes.
