Compositions are provided for lubricant base stocks produced from feeds such as vacuum resid or other 510 C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.

The present invention describes a water based semi-synthetic metal working fluid comprising a base oil, an organic acid, emulsifiers, a concentrate additive, water and a microbial growth control agent which comprises an alky alcohol amine.

Disclosed is a method of producing an estolide, including a) converting biomass-derived oil into a fatty acid mixture, b) separating the fatty acid mixture into a C16 saturated fatty acid and a C18 unsaturated fatty acid, c) converting the C16 saturated fatty acid into a C15 or C16 linear internal olefin, d) subjecting the C15 or C16 linear internal olefin to an estolide reaction using a linking agent, thus obtaining an estolide A, e) subjecting the C18 unsaturated fatty acid to partial hydrogenating to increase the amount of oleic acid, and f) subjecting the oleic acid to an estolide reaction using a linking agent and then esterification, thus obtaining an estolide B.

The present invention relates to synthetic ester compositions, and to dielectric fluid compositions containing them, as well as to methods of manufacturing the ester compositions and dielectric fluid compositions containing them, and to an electrical apparatus containing the dielectric fluid compositions.

Lubricant compositions comprising an improved ashless organic friction modifier additive, capable of reducing both friction and wear, is provided. It has been found that mixtures of fatty-alkanolamides containing secondary hydroxyls on the amino alkyl substituent, such as amide mixtures prepared from bis(2-hydroxyporopyl)amine and mixtures of at least two different C.sub.8-24 fatty acids, provide better oil solubility and friction reduction than alkanolamides with primary hydroxyl functionality, such as amide mixtures prepared from di-ethanol)amine.
