Abstract: The present invention relates to methods of demulsifying employing condensates as demulsifiers for oil-in-water emulsions and prepared from A) a precondensate from one or more trialkanolamines of the general formula I (I) in which R1 to R3 denote the same or different 1,2-alkylene groups of from 2 to 4 carbon atoms, and B) from 0.1 to 30% w/w, based on said precondensate, of one or more of the following compounds II: a) urea or a urea derivative of the general formula IIa (IIa) b) a urea derivative of the general formula IIb (IIb) c) a urethane of the general formula IIc (IIc) and/or d) a urethane of the general formula IId (IId) in which R1 is hydrogen, C1-C20-alkyl or C2-C20-alkenyl, R2 and R3 are the same or different and denote hydrogen or C1-C4-alkyl, R4 is C1-C4-alkyl and R5 is C1-C12-alkylene.

Abstract: Trialkanolamine polyethers, obtainable by condensing tri-alkanolamine(s) in the presence of (hypo)phosphorus acid, are useful as demulsifiers in 0/W emulsion. The trialkanolamines are of formula (I), where R1-R3 = 1,2-(2-4C)alkylene.
