Abstract
Abstract An alpha-olefin is oligomerized in the presence of a three-component catalyst comprising a particulate solid adsorbent having boron trifluoride and water adsorbed on the solid adsorbent. For example, 1-decene is oligomerized to a product predominating in the trimer and tetramer using silica as the solid adsorbent.

58 words
The process for oligomerizing an alpha-olefin having from three to twelve carbon atoms and mixtures thereof with a heterogeneous catalyst which comprises contacting said alpha-olefin in a reactor at a temperature between about -50° and about 150° C. with a three-component solid catalyst comprising a solid adsorbent in particulate form having a boron trifluoride and water adsorbed thereon.
Claim 2
Dependent Claim
58 words
The process for oligomerizing an alpha-olefin having from three to twelve carbon atoms and mixtures thereof with a heterogeneous catalyst which comprises contacting said alpha-olefin in a reactor at a temperature between about -50° and about 150° C. with a three-component solid catalyst comprising a solid adsorbent in particulate form having a boron trifluoride and water adsorbed thereon.
Claim 3
Dependent Claim
