A process for the preparation of surfactants is described comprising reacting a phosphorus acid ester of the following Formula (IV) wherein Rt is aryl, R2 is alkyl or aryl, with a hydrophilic polyoxyalkylene of the following Formulas (VIII), or (IX) wherein R3 is alkyl and A is a hydrophilic polyoxyalkylene chain, and which reaction results in an intermediate compound Formulas (XI), (XII), or (XIII); reacting the intermediate compound selected from the group consisting of Formulas (XI) through (XIII), with a hydroxylic compound R1-OH (X) to yield surfactant precursors comprised of Formulas (V), (VI), and (VII), respectively: 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.
