Abstract: or 1-aminobenzene-4- Beta -hydroxyethyl-sulfone of the formula

Compounds of the formula

WHEREIN Z is a grouping of the formula HO3SO-CH2-CH2- or CH2 CH, and their alkali metal salts, and a process for preparing them by dissolving or suspending 1-aminobenzene-4-( Beta sulfatoethyl)-sulfone of the formula
in a mixture of sulfuric acid and sulfur trioxide at a temperature of from -15* to +10*C and then continuing the reaction at a temperature of from 115* to 150*C, whereupon, if desired, the sulfuric acid ester is treated, optionally after its isolation with an alkaline agent and the vinyl compound thus obtained is isolated in the form of an alkali metal salt or an acid. The novel compounds are suitable for the preparation of valuable dyestuffs containing an amino coupling component.

Abstract: Water-soluble reactive azo dyestuffs of the formula (1)

WHEREIN R represents a hydrogen atom or a lower alkyl radical a cyclohexyl radical or a phenyl radical, Q represents a hydrogen atom or a hydroxyl group and Z stands for one of the groupings (2a), (2b) or (2c) -CH2-CH2-OSO3H(2a) -CH CH2(2b) -CH2-CH2OH(2c) AND N STANDS FOR THE INTEGER 1 OR 2, WHICH ARE VERY SUITABLE FOR DYEING AND PRINTING MATERIALS MADE OF NATURAL CELLULOSE FIBERS, PARTICULARLY COTTON, REGENERATED CELLULOSE FIBERS, LINEN, SILK, POLYAMIDE AND POLYURETHANE FIBERS, ESPECIALLY WOOL, PREFERABLY UTILIZED ACCORDING TO THE TECHNICALLY USUAL DYEING AND PRINTING PROCESSES FOR REACTIVE DYESTUFFS. They posses an excellent affinity towards wool fibers and they are dyed from an acid, weakly acid or neutral dyeing bath at 70*C to 120*C. They are distinguished by a very good color build-up, a good levelness of the dyeings, very good fastnesses to processing and very good fastnesses to use, also on chlorinated wool. A particular characteristic of these dyestuffs is the very good suitability for the preparation of combination dyeings in mixtures with other dyestuffs on account of the fact that the rate of absorption from the dyeing bath on the wool fiber can be controlled by the pH value of the dyebath.
