Abstract

Abstract Cresylic acid ethoxylation is catalyzed by basic compounds and salts of alkaline earth metals. Ethoxylates from such reactions have narrow ethylene oxide distributions, lower pour points and lower by-products as compared to alkali base catalyzed ethoxylation. Suitable catalysts include strontium-containing and barium-containing materials. The catalyst also includes co-catalyst combinations using these materials with one or more promoters including polyols, amines, amides, carboxylic acids and phenols. The co-catalyst combinations can be preformed prior to introduction into the reaction mixture.
