The present invention relates to a new process for obtaining fatty acids with improved color, odor and heat stability which is characterized in that:

Process for obtaining fatty acids with improved odor, color and heat stability

Processes for preparing conjugated fatty acid products are described wherein (a) a composition which comprises a fatty acid ester having at least two unconjugated, carbon-carbon double bonds is provided; (b) the fatty acid ester is conjugated in the presence of a water-free base; (c) phosphoric acid is added to the conjugated fatty acid ester such that phosphate salts are precipitated; and (d) the precipitated phosphate salts are removed.

Method for producing conjugated fatty acid esters

A method for preparing a polyol useful in the formation of an isocyanate casting resin or coating composition is presented involving the reaction of an essentially C fatty acid mixture with a monofunctional alcohol to form a fatty acid ester mixture, forming a epoxidized fatty acid ester mixture from the fatty acid ester mixture, and reacting the epoxidized mixture with an aliphatic alcohol to form a polyol. The polyol can be further reacted with an isocyanate to form a casting resin or coating composition. The fatty acid mixture contains at least 80 percent oleic acid. Polyols prepared by this method provide good color quality and improved color stability during storage when used in the production of isocyanate casting resins and coating compositions.

Methods of preparing casting resins and coating compositions using polyols derived from high oleic acid content fatty acid mixtures

A process for producing coating compositions involving: (a) providing a reactive diluent, (b) providing an inert solvent, (c) providing a polymeric polyol, (d) providing an isocyanate, (e) reacting (a)-(d) in a reactive diluent comprising a ring opening product of a carboxylic acid ester epoxide with a dihycric or higher alcohol.

Fatty chemical polyalcohols as reagent thinners

A process for breaking an emulsion into a water phase and an oil phase involving: (a) providing an emulsion containing an oil phase and a water phase; (b) providing an alkoxylated C,carboxylic acid ester derived by the addition of ethylene oxide and/or propylene oxide onto a ring opened epoxidized C,carboxylic acid triglyceride which is ring opened with a C,carboxylic acid; and (c) contacting the emulsion with a demulsifying effective amount of the alkoxylated C,carboxylic acid ester. Said process has application on crude oil emulsions.

Method for demulsifying emulsions

A process for cleaning boreholes, drilling equipment and drill cuttings is presented involving the application of a cleaning composition to surfaces and the subsequent removal of the cleaning composition and soils. The cleaning composition contains a cleaning additive having alkoxylation products obtained by the reaction of ethylene oxide, propylene oxide, butylene oxide or mixtures thereof with an OH-containing C,carboxylic acid or derivative thereof, where structural units corresponding to formula (I):
