ABSTRACT:
A monoolefin oligomerization process which gives high yields of dimer and trimer at high monoolefin conversions in a single stage reaction is described. The process involves contacting a C.sub.6-20 vinyl olefin with a catalyst comprising boron trifluoride and from 0.075 to 0.5 mol %, based on the total quantity of monoolefin being used, of an alcohol catalyst promoter. The oligomerization is performed at a temperature below about 40.degree. C. and under a pressurized atmosphere of boron trifluoride in the range of 2 to 4 bars gauge until the monoolefin conversion is at least 95% and the combined total of dimer and trimer in the liquid reaction mixture is at least 60% by weight.
