Process for producing high-purity azo dyes |
| abstract |
A process for producing high-purity azo dyes is characterised in that (a) at least 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, C4-C10 ether alcohols and halogenated aromatic compounds 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. |
