摘要： Dyestuffs of the formula ##STR1## in which D is the radical of an aromatic or heterocyclic diazo component andK is the radical of an aromatic or heterocyclic coupling component, or is the radical of an active methylene compound,are obtained in an ecologically advantageous manner by reacting an aromatic or heterocyclic diazo components of the formulaD--NH.sub.2and a coupling component of the formulaH--Kwith a nitrite, for example NaNO.sub.2, in the presence of CO.sub.2 at a pressure of 5-100 at. The process is suitable in particular for the preparation of concentrated dye-stuff solutions, because expensive operations, such as, for example, pressure permeation and reverse osmosis, can be omitted.

摘要： A new and very advantageous Process had been found for the preparation of azo dyestuffs by diazotation and coupling in which the synthesis is carried out without the hitherto usual addition of an acid, with the proviso that at least one of the diazo and coupling components contains at least one acid group. Besides the saving of reaction material and subsequently of alkali for neutralization of the reaction medium and isolation of the dyestuff, highly concentrated solutions of the dyestuff and salt-free or practically salt-free dyestuffs can be obtained, and waste-water is no longer charged with big amounts of salts.

摘要： The invention describes a process for the preparation of formulations of water-insoluble to sparingly soluble azo dyes by simultaneous diazotization and coupling in a single step reaction, filtering the dye dispersion and, if desired, drying the dyestuff, which process comprises carrying out said simultaneous diazotization and coupling by intimately mixing the aqueous solution or suspension of the reactants, in the presence of one or more surface-active agents, concentrating the dilute dye dispersion by membrane separating methods, and at the same time at least partially removing salt and/or acid from the dispersion and converting it into a storage stable liquid formulation or, by drying, into a solid dye formulation.
