    摘要: There is disclosed a process for coupling one or more different diazo components with resorcinol on an industrial scale. The process comprises adjusting and stabilizing the coupling pH of the resorcinol prior to the reaction with the aid of a buffer system and keeping it constant during the coupling reaction or reactions by controlling the ratio of flow of the streams of the diazo component or components and the base. The process makes it possible to prepare mono- and polyazo dyes in excellent uniform quality and yield.

    摘要: Substituted 2-nitro-2'hydroxyazobenzenes are prepared by adding an aqueous mineral acid solution of a diazotized o-nitroaniline to a strongly alkaline lower alkanol or aqueous lower alkanol solution of a substituted phenol, containing sufficient alkali metal hydroxide to assure a pH value substantially over 11 and an excess of hydroxyl ion in the reaction mixture even after all the acidic diazonium salt solution is added, wherein the reaction solvent mixture is at least 50% by weight of lower alkanol, at a reaction temperature between -15.degree. C. and +30.degree. C.The o-nitroazobenzenes obtained are intermediate products useful in the manufacture of benzotriazole UV absorbers.

    摘要: Disperse dyestuffs of the formula ##STR1## wherein Q.sub.1 and Q.sub.2 are hydrogen or the group V-(A-O).sub.n Z, but do not at the same time represent hydrogen, A -- denotes an alkylene group, V -- denotes a direct bond or a bridge member, Z -- denotes hydrogen, alkyl, aryl, aralkyl or acyl and N -- denotes an integer from 2-10 and the rings A, B and D can be further substituted. The dyestuffs are suitable for dyeing polyester fibres from an aqueous liquor by the exhaustion process since they are distinguished by a good affinity and build-up power. The dyeings are very clear and display good general fastness properties, such as fastness to light, sublimation and measuring.
