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.
