    摘要： A process for the preparation of a pH-stabilized, liquid, aqueous dyestuff composition of the lithium azo dyestuff of formula (1) ##STR1## which composition has an Na-content of less than 0.2% b.w., based on the lithium azo compound of formula (1), in which process the lithium salt of 4-(.beta.-sulfatoethylsulfonyl)-aniline is diazotized in a mineral acid aqueous solution or in a mineral acidic solution containing a watermiscible organic solvent by means of an essentially sodium-free derivative of nitrous acid as the diazotizing agent, such as nitrosyl sulfuric acid, and the diazotized aniline is coupled in said solution with the lithium salt of 1-hydroxy-7-acetylamino-naphthalene-3-sulfonic acid and a buffering substance for adjusting and maintaining the pH of the composition at a value between 3 and 6.5 is added to that solution subsequent to the above-mentioned diazotizing step or preferably during said or subsequent to said coupling step, the amount of the buffering substance added is from 0.5 to 5% b.w. of said composition,and furthermore concentrated pH-stabilized liquid aqueous dyestuff compositions containing the above-indicated lithium azo dyestuff of formula (1) and an Na-content, based on the weight of said dyestuff of formula (1), of less than 0.2% b.w. and said buffering substance to maintain the pH between 3 and 6.5, the amount of the azo dyestuff of formula (1) being at least about 10% b.w. and up to 25% b.w. of the composition.

    摘要： A process is described for separating sodium sulfate from aqueous solutions, containing less than 2% by weight of chloride, of certain fiber-reactive copper-formazan dyestuffs wherein this dyestuff solution is cooled down to a temperature between +5.degree. C. and -15.degree. C. In the course of the cooling the sodium sulfate precipitates in the form of the decahydrate and can be separated off in conventional manner, for example by filtration. The products obtained in this way are liquid low-salt aqueous copper-formazan dyestuff preparations which contain less than 4% by weight of sodium sulfate.
