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: Chemically modified proteins obtainable by reacting casein, collagen, gelatin, albumin or mixtures thereof (a) with 0.5 to 15% by weight of chlorine or of a compound which liberates chlorine under the reaction conditions, in an aqueous medium at a pH of from 0 to 7 or (b) with 0.5 to 50% by weight of a non-aromatic mono- or disulfonic acid which contains in its organic radical one or more groups or structural features which react with nucleophiles, in an aqueous medium at a pH of from 6 to 14, are used as dispersants in colorant formulations.

Abstract: The process is of sulphonating aryl compounds obtainable by pyrolysis of a naphthenic residual oil and fractional distillation of the pyrolysis products of the fraction produced at from 100 to 120 DEG C under atmospheric pressure, sulphonating this aromatic fraction using oleum at temperatures of from 120 to 160 DEG C in an amount of from 0.7 to 1.2 parts by weight of oleum, based on oleum having an SO3 content of 24 % by weight, per part by weight of the aromatic fraction, and subsequently condensing the arylsulphonic acids with formaldehyde in a known manner. The condensation products are used as dispersants, in particular in the preparation of dye formulations.
