Abstract
A process for the co-oligomerization of 1-dodecene and 1-decene to produce a polyalphaolefin having a kinetic viscosity of 4 to 6 cSt at 100° C., a Noack weight loss of 4 to 9%, a viscosity index of 130 to 145, and a pour point of −60° C. to −50° C.
Claims9
A process for producing a polyalphaolefin product, comprising co-oligomerizing a mixture comprising from about 60 to about 90 weight percent of 1-dodecene and 1-decene in the presence of a BF3 catalyst and an alcohol promoter at a temperature in the range of from about 20° C. to about 60° C. thereby form a polyalphaolefin having a kinematic viscosity at 100° C. in the range of from about 4 to about 6 cSt, a Noack weight loss in the range of from about 4 to about 9%, a viscosity index in the range of from about 130 to about 145 and a pour point in the range of from about −60° to about −50° C., wherein the weight ratio of 1-dodecene to 1-decene is at least about 2:1 and 1-decene is introduced continuously or intermittently during the reaction period.
