Abstract: Process for the preparation of nitrobenzophenones by reaction of benzene or its derivatives with nitrobenzoyl chloride in the presence of a Lewis acid, a colour-fast modification of 1,4-dimethyl-5-cyano-3-[4-(2,4-dimethylbenzoyl)phenylazo]-2-hydroxy-py rid-6-one, and its use for dyeing or printing synthetic fibre material.

Abstract: A dispersant having improved bioelimination capacity or biodegradability for use in dye and pigment formulations, as a tanning aid, in plastics manufacture and in crop protection formulations is characterised by a content of 3 to 50 % by weight of one or more aromatic or long-chain aliphatic carboxylic acids, salts thereof or anhydrides thereof, or a mixture of these.

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.
