摘要：Novel organic, water-soluble compounds having fiber-reactive and fiber-finishing properties and containing, as a fiber-reactive group, one or two beta -chloroethylsulfonylmethyl-benzoic acid amide groups. These compounds can be prepared (1) by reacting novel beta -chloroethylsulfonylmethyl-benzoic acid halide compounds with an organic, water-soluble compound having fiber-finishing properties and containing one or two amino groups, or (2) analogously to known and usual procedures, from precursors containing the beta -chloroethylsulfonylmethyl-benzoic acid amide grouping. The novel fiber-finishing compounds are applied to and fixed on suitable fiber materials, especially cellulose fiber material and natural or synthetic polyamide fiber materials, by methods corresponding to those which are conventional for application and fixation of fiber-reactive compounds. The above-mentioned beta -chloroethylsulfonylmethyl-benzoic acid halides are synthesized by monochlorinating the methyl grouping of a toluenecarboxylic acid or an alkyl ester thereof or an acid halide thereof, converting this monochlorinated compound by reaction with 2-mercaptoethanol in aqueous solution, optionally with simultaneous hydrolysis of the carboxylic acid chloride group, to form the thioether compound, hydrolyzing the carbalkoxy grouping optionally present in this thioether compound, and then oxidizing said thioether compound by means of an oxidizing agent to form the corresponding sulfonyl compound; the beta -hydroxyethylsulfonylmethyl grouping is subsequently reacted with a chlorinating agent.
