Abstract: 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.

Abstract: This invention relates to novel copper complex formazan compounds of the formula ##STR1## in which M is hydrogen or the equivalent of a metal and R is hydrogen or chlorine. The invention also relates to a process for their manufacture. The compounds can be used as dyestuffs, in particular fiber reactive dyestuffs for dyeing cellulose fiber materials, wool, or synthetic polyamide fiber materials for example, on which they exhibit intense blue dyeings having good fastness properties.
