This invention relates to novel N-alkyl-N-(amino-phenylsulfonyl)-aminoalkylphosphonic acids and to processes for their preparation. These compounds are useful as intermediates, especially for the manufacture of dyes containing phosphonic acid groups in their structure. Such dyes are reactive with cellulosic fibers and fabrics in the presence of carbodiimides at elevated temperatures.
本发明涉及新型N-烷基-N-(氨基苯基磺酰基)-氨基烷基膦酸及其制备方法。这些化合物可用作中间体,特别适用于制造含有膦酸基团的染料。这些染料在存在卡波二亚胺酯的条件下,在高温下与纤维素纤维和织物发生反应。
