    • A process for the preparation of surfactants is described comprising reacting a phosphorus acid ester of the following Formula (IV) ##STR1## wherein R.sup.t is aryl, R.sup.2 is alkyl or aryl, with a hydrophilic polyoxyalkylene of the following Formulas (VIII), or (IX) ##STR2## wherein R.sup.3 is alkyl and A is a hydrophilic polyoxyalkylene chain, and which reaction results in an intermediate compound Formulas (XI), (XII), or (XIII); ##STR3## reacting the intermediate compound selected from the group consisting of Formulas (XI) through (XIII), with a hydroxylic compound R.sup.1 -OH (X) to yield surfactant precursors comprised of Formulas (V), (VI), and (VII), respectively: ##STR4## and, oxidizing said phosphorus ester-linked surfactant precursors selected from the group consisting of Formulas (V), (VI) and (VII), with an oxidizing agent to produce the surfactants.
    • 描述了制备表面活性剂的方法,其包括使下式(Ⅳ)的磷酸酯,其中R t为芳基,R 2为烷基或芳基,与下式(Ⅷ)或(Ⅸ)的亲水性聚氧化烯反应,其中 R3是烷基,A是亲水性聚氧化烯链,该反应产生中间体化合物式(XI),(XII)或(XIII); 使选自式(XI)至(XIII)的中间体化合物与羟基化合物R1-OH(X)反应,得到由式(V),(VI)和(VII)组成的表面活性剂前体 并且用氧化剂氧化所述选自式(V),(VI)和(VII)的所述磷酯连接的表面活性剂前体以产生表面活性剂。
