A method for producing a lubricant in producing an overbased calcium sulfonate, which is converted from the vaterite form into the calcite form and, finally, a calcium sulfonate grease is produced by heating the mixture. A lubricant may comprise at least one ester composition, calcium carbonate and at least one overbased alkylbenzene sulfonate. The basicity of the mixture is limited during the preparation of the overbased calcium sulfonate to a TBN of at most 550 mg KOH/g and during the conversion of the calcium sulfonate to a TBN of at most 450 mg KOH/g. Both the calcium sulfonate and the grease containing said calcium sulfonate may be produced exclusively on an ester basis, so that the end product does not contain any mineral oil and is therefore easily and completely biodegradable.

A higher-yielding process for the production of monoglycerides in which triglycerides are enzymatically reacted with a catalytic amount of an esterase, preferably lipase, that has been activated by the addition of alkaline salts, in the presence of linear or branched alcohols containing 1 to 8 carbon atoms, then the esterase may be deactivated and it and the remaining alcohol removed, with the monoglycerides thus produced useful in lubricants, fuel additives, and emulsifying constituents in foods, and cosmetic and/or pharmaceutical formulations.

Production and use of monoglycerides

There is described a fuel additive composition comprising an oleic alkanolamide and an alkoxylated oleic acid. There is also described a fuel composition comprising a hydrocarbon fuel and a fuel additive comprising an oleic alkanolamide and an alkoxylated oleic acid and also a method of running a combustion engine using the fuel if the invention.

Fuel additives

A process for imparting lubricity to an aqueous drilling fluid used in geological exploration involving: (a) providing an aqueous drilling fluid; (b) providing a lubricant component containing a partial glyceride of predominantly unsaturated fatty acids having from about 16 to 24 carbon atoms; and (c) introducing the partial glyceride into the aqueous drilling fluid.
