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: 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.

Abstract: Dye compsns. comprise 20-60 wt.% of a benzophenone azo dye, 40-80 wt.% of a dispersant and 0-5 wt.% of other additives. The dye is of formula (I), where one of R1 and R2 is H and the other is OMe or OEt, or R1 = R2 = Me, and R3 = 1-4C alkyl. The dispersant is based on a lignosulphonate or an arylsulphonic acid/formaldehyde condensate and contains 3-50 wt.% of a component selected from aromatic or higher aliphatic carboxylic acids and their salts and anhydrides. Cpds. (I) are described in DE 2015172, DE 2157229 and EP 413229. The dispersants are described in EP 91109017. USE/ADVANTAGE - The compsns. are useful for dyeing synthetic textile materials, esp. polyester or polyester/cotton, giving strong yellow shades with good light and thermofixation fastness. The dispersants are highly biodegradable.

Abstract: The invention relates to methods for reacting (di)amines as substrates in the presence of a lysine oxidase arid a reducing agent, resulting in alcohols, diols or cyclic secondary amines. In a particular embodiment, the invention is directed to methods of preparing cyclic secondary amines suitable for ultimately synthesizing piperidine-2-carboxylic acid and proline derivatives, useful, for example as thrombin inhibitors.

Abstract: The use of dispersants (I) in a composition containing ultraviolet (UV) absorber is claimed. (I) are condensation products based on arylsulphonic acids (II) and formaldehyde (HCHO) and are obtained by (a) sulphonating aromatic compounds (III) to (II) and (b) condensing (II) with HCHO. Step (a) and/or (b) is carried out in the presence of 5-50 wt.% carboxylic acid, salt or anhydride containing aromatic groups with respect to (III). Also claimed are (i) a method of producing the composition comprising mixing the required amounts of (I) and UV absorber so that they are finely dispersed. (ii) the composition per se and (iii) textiles treated with the composition, which have increased light fastness.
