Abstract

Described is a process for isomerizing .alpha.-olefin to produce olefinic oil having a viscosity at 100.degree. C. of no more than about 1.6 cSt, a viscosity at 40.degree. C. of no more than about 3.8 cSt, and a pour point of 0.degree. C. or lower, preferably -10.degree. C. or lower. The process comprises contacting the .alpha.-olefin having from about 14 to about 20 carbon atoms with a catalytic quantity of nonmetallic sulfonic or perfluorosulfonic acid resin catalyst under identified isomerization conditions, thereby producing deep internal olefin having the desired combination of physical properties.
