Abstract
A synthetic hydrocarbon fluid is prepared by oligomerizing an olefin reactant in the presence of a catalyst prepared by reacting tungsten hexafluoride and a branched-chain aliphatic alcohol at a moderate temperature. For example, 1-butene is oligomerized at a temperature of about 40.degree. C. in the presence of a catalyst obtained by reacting tungsten hexafluoride and isopropanol in a four to one mol ratio. The liquid oligomer product is then hydrogenated to remove residual unsaturation.
