A process to make an alkylate base oil having a viscosity index greater than or equal to 90, comprising: a. converting an at least one dimeric ketone to an at least one alcohol; b. dehydrating the at least one alcohol to make one or more corresponding olefins; and c. alkylating at least one isoalkane with the one or more corresponding olefins to form the alkylate base oil.

A water-soluble lubricant composition for warm and hot plastically working of an aluminum material comprising (A) hydrophilic polyester resin, (B) alkali metal salt of a polymaleic acid resin, (C) alkali metal salt of carboxylic acid and (D) water, and optionally (E) a wax.

Methods for making alpha olefin oligomers and polyalphaolefins include a step of contacting a C.sub.4 to C.sub.20 alpha olefin monomer and a catalyst system containing a metallocene, a first activator comprising a solid oxide chemically-treated with an electron withdrawing anion, and a second activator comprising an organoaluminum compound. The alpha olefin oligomers and polyalphaolefins prepared with these catalyst systems can have a high viscosity index combined with a low pour point, making them particularly useful in lubricant compositions and as viscosity modifiers.

Disclosed is a method for preparing a low-viscosity oil including more than 50 wt % of 9-methyl-11-octyl-heneicosane. The method uses a specific metallocene catalyst and makes it possible to prepare a polyalphaolefin oil (PAO) in which the kinematic viscosity at 100° C., measured according to standard ASTM D445, ranges from 3 to 4 mm.sup.2/s.sup.−1. The oil can be used as a high-performance lubricant for lubrication in the fields of engines, gears, brakes, hydraulic fluids, coolants and greases
