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

The present invention relates to specific derivatives of dimer fatty acids, compositions comprising them and a method to reduce pour points.

Provided are compositions, additives for forming compositions, methods of operating apparatus in fluid communication with the compositions, and apparatus comprising the compositions. For example, the composition may include a polyalphaolefin component of from about 95% to about 99.5% w/w. The composition may include an additive component. The additive component may include an anti-wear agent. The anti-wear agent may be from about 0.1% to about 2% w/w. The anti-wear component may be characterized by an acid value of at least about 1 mg KOH/g. The additive component may include an aryl amine antioxidant agent, an anti-rust agent, and a metal deactivator agent. The composition may be characterized by a kinematic viscosity at 100° C. of at least about 5 centiStokes, a viscosity index of at least about 80, and an acid value in mg KOH/g of between about 0.1 and about 1.

Methods of making branched isoparaffin compositions derived from natural oil based linear internal olefins are disclosed. Uses of branched isoparaffins formed by such methods are also disclosed.

This method for producing a lubricating oil composition includes: a step of dissolving fullerenes in a base oil mainly composed of a multiply alkylated cyclopentane oil or an ionic liquid containing an imide as a negative ion to obtain a fullerene solution; and a step of producing fullerenes adduct by subjecting the above-described fullerene solution to a heat treatment in a non-oxidizing atmosphere.

A lubricating grease composition, and more specifically, to a lubricating grease composition which, when used with an article clamping device, such as a chuck, produces excellent lubricating properties whilst remaining strongly adhered to metal parts in the clamping mechanism of the device and showing enhanced chemical and physical resistance to fluids such as cutting fluids with which they come into contact.

Provided herein are olefinic feedstocks derived from conjugated hydrocarbon terpenes (e.g., C.sub.10-C.sub.30 terpenes), methods for making the same, and methods for their use.

The disclosure relates to a biobased metal-working fluid (MWF) composition and method for making same, and more particularly metal-working fluid with biobased lubricants with improved emulsion stability. At least 50 wt. % of the base oil component in the MWF concentrate is a plant-derived liquid decarboxylated rosin acid oil (“DCR”). The DCR comprises 50 to 100 wt. % of tricyclic compounds having 18-20 carbon atoms, one or more C═C groups, and m/z (mass/charge) value of 220-280; an oxygen content of <5%; a density of 0.9 to 1.0 g/cm.sup.3 at 20° C.; and an acid value of <10 mg KOH/g. The resulting MWF is characterized as having comparable if not better performance compared to a MWF containing only mineral oil (e.g., Group I or Group II).

A method for producing a renewable base oil from a feedstock of biological origin includes providing a feedstock, the feedstock including: 2-95 wt % of a mixture of free fatty acids; 5-98 wt % fatty acid glycerols selected from mono-glycerides, di-glycerides and tri-glycerides of fatty acids; 0-50 wt % of one or more compounds selected from the list consisting of: fatty acid esters of the non-glycerol type, fatty amides and fatty alcohols; a major part of the feedstock being a mixture of free fatty acids and fatty acid glycerols; subjecting all or part of the feedstock to ketonisation reaction conditions where two free fatty acids react to yield a ketone stream, and subjecting the ketone stream to both hydrodeoxygenation and to hydroisomerisation reaction conditions, to yield a deoxygenated and isomerised base oil product stream containing the renewable base oil.

Provided herein are olefinic feedstocks derived from conjugated hydrocarbon terpenes (e.g., C.sub.10-C.sub.50 terpenes), methods for making the same, and methods for their use.
