Title:
PROCESS FOR PREPARATION OF SELECTIVELY BRANCHED DETERGENT PRODUCTS
Document Type and Number:
WIPO Patent Application WO2001085651
Kind Code:
A3
Abstract:
A process for making a selectively branched alcohol composition, comprising: contacting an oligomerization catalyst under oligomerization conditions with a lower olefin feed comprising linear olefins having at least 3 carbon atoms, said oligomerization catalyst being effective to oligomerize said linear olefins to produce selectively branched olefins having up to 36 carbon atoms, wherein one or both of said olefins selected from the group consisting of said selectively branched olefins and said lower olefin feed comprises a concentration of an impurity selected from the group consisting of one or more dienes and one or more phosphorus-containing compounds; reducing said concentration of said impurity in at least one of a material selected from the group consisting of said lower olefin feed and said selectively branched olefins; and converting said selectively branched olefins to said selectively branched alcohol composition.
