UNSUPPORTED HETEROPOLYACID CESIUM SALT CATALYSTS FOR DIMERIZATION AND/OR OLIGOMERIZATION OF OLEFINS

摘要

The present invention relates to unsupported metal (e.g., cesium) substituted heteropolyacid catalyst compositions useful for the production of butene dimers and/or oligomers from a mixed butenes feed, in which, under mild conditions, all isomers of mixed butenes produce highly branched C8 and C8+ olefins.
