    摘要: 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 C10-22 carboxylic acid or derivative thereof, where structural units corresponding to formula (I): comprise one or both of the 9/10 or 13/14 positions, wherein R1 is a hydrogen atom, an OH group or a OR2 group, R2 is an alkyl group containing 1 to 18 carbon atoms, an alkenyl group containing 2 to 18 carbon atoms or a group corresponding to formula (II): where R3 is a hydrogen atom, an alkyl group containing 1 to 21 carbon atoms or an alkylene group containing 2 to 21 carbon atoms. The cleaning composition is biodegradable.

    摘要: 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 C18 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.
