ABSTRACT:
Olefinic hydrocarbons which contain from three to about six carbon atoms may be subjected to oligomerization reactions as well as being used as alkylating agents in the alkylation of alkylatable hydrocarbons by treatment at reaction conditions in the presence of a catalyst comprising a phosphorus fluoride such as phosphorus trifluoride or phosphorus pentafluoride composited on a high surface area metal oxide such as gamma-alumina. The oligomers which are obtained in the oligomerization process will contain less branching than those which are obtained when utilizing other catalysts.
