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.
具有纤维反应和纤维整理特性的新型有机水溶性化合物,包含一个或两个β-氯乙基磺酰甲基苯甲酰胺基作为纤维反应基团。这些化合物可以通过以下方法制备:(1)将新型β-氯乙基磺酰甲基苯甲酸卤化物与含有一个或两个氨基的有机水溶性化合物反应,该化合物具有纤维整理特性;或者(2)类似于已知和通常的方法,从含有β-氯乙基磺酰甲基苯甲酸酰胺基团的前体中合成。新型纤维整理化合物通过与适当的纤维材料(特别是纤维素纤维材料和天然或合成聚酰胺纤维材料)应用和固定,通过与纤维反应性化合物相应的应用和固定方法实现。上述β-氯乙基磺酰甲基苯甲酸卤化物通过单氯化甲基基团的甲苯羧酸或其烷基酯或酸卤化物,通过与2-巯基乙醇在水溶液中反应,可选地与羧酸氯基团同时水解,形成硫醚化合物,水解该硫醚化合物中可能存在的羧酸酯基团,然后通过氧化剂氧化该硫醚化合物,形成相应的磺酰化合物来合成;随后β-羟乙基磺酰甲基基团与氯化剂反应。
