Abstract

C.sub.8 -C.sub.20 olefins are dimerized in the presence of hydrofluoric acid, by (1) contacting for about 1 to 30 minutes, at least one C.sub.8 -C.sub.20 olefin with liquid hydrofluoric acid at a temperature of between about -20.degree. C. and +60.degree. C., in a molar ratio of hydrofluoric acid to olefin of between about 1:1 and 50:1; (2) immediately after the contacting, the hydrofluoric acid present is removed almost instantaneously from the dimerization medium; (3) a defluorination of the said medium is effected; and (4) the resultant oledimers are recovered.
