Abstract
A process for producing hexene-1 oligomer by a process which comprises oligomerizing hexene-1 in the presence of a Friedel-Crafts catalyst, such as boron trifluoride, and a promoter, such as water, the improvement comprising dissolving hexene-1 in a hydrocarbon solvent comprising 10-75% of the reaction mixture and conducting the oligomerizing in the hydrocarbon solvent. The hydrocarbon solvent has a minimum boiling point of 60.degree. C. There is an increase in both the reaction rate and trimer yield of product.
Claims5
In a process for producing saturated hexene-1 oligomer by a process which comprises oligomerizing hexene-1 in the presence of a Friedel-Crafts catalyst and promoter, distilling off the monomer and dimer and hydrogenating the residual product, the improvement comprising dissolving hexene-1 in said hydrogenated residual product comprising 10-75% of the reaction mixture and conducting said oligomerizing in said hydrogenated residual product whereby the oligomerization rate is substantially increased.
