摘要： A process for producing high-purity azo colorants is characterized in that (a) at least the azo coupling is carried out in a micro-reactor, (b) the azo-dye produced in the micro-reactor is brought into intimate contact with an organic solvent from the group of the C3-C6 alcohols, the C4-C10 ether alcohols and the halogenated aromatics at a temperature from 0 to 60° C., and (c) the azo dye produced in the micro-reactor is subjected to membrane purification in an aqueous or solvent-containing suspension.

摘要： The invention provides a process for the fine division of pigments which comprises dissolving coarsely crystalline crude pigments in a solvent and precipitating them with a liquid precipitation medium by spraying the pigment solution and the precipitation medium through nozzles to a point of conjoint collision in a reactor chamber enclosed by a housing in a microjet reactor, a gas or an evaporating liquid being passed into the reactor chamber through an opening in the housing for the purpose of maintaining a gas atmosphere in the reactor chamber, and the resulting pigment suspension and the gas or the evaporated liquid being removed from the reactor through a further opening in the housing by means of overpressure on the gas entry side or underpressure on the product and gas exit side.

摘要： The invention relates to a method for carrying out chemical and physical methods, in particular for producing organic pigments or the preparations based thereon. The inventive method consists in injecting at least two liquids or suspensions in a vertex chamber, without using carrying gas, with the aid of two end pipes which are not coaxially oriented. Said injection is carried out at a pressure ranging from 1 to 1000 bars and in conformity with a volume flow rate ranging from 5 to 500 l/h, thereby producing the vertex mixing of a liquid phase with a material modification, and continuously extracting said liquid phase from the vertex chamber through a removing hole, the material modification being obtained
