Abstract:
1. A process for producing a polyalphaolefin (PAO) comprising contacting a feed consisting of 40-60 wt. % 1-decene and 60-40 wt. % 1-dodecene with an oligomerization catalyst in an oligomerization reaction zone under oligomerization conditions for a time sufficient to produce either a PAO having a kinematic viscosity of about 40 cSt at 100° C. (ASTM D-445), a viscosity index of at least about 150 (ASTM D-2270), and a pour point of less than or equal to about −42° C. (ASTM D-97), or a PAO having a kinematic viscosity of about 100 cSt at 100° C. (ASTM D-445), a viscosity index of at least about 170 (ASTM D-2270), and a pour point of less than or equal to about −30° C. (ASTM D-97), wherein the PAO has a number average molecular weight of from about 1200 to about 4000 wherein said oligomerization catalyst is selected from the group consisting of AlCl 3 , AlBr 3 , and mixtures thereof.
