Processes for preparing surfactants

摘要

A process for the preparation of surfactants represented by Formulas (I), (II) or (III); or optionally mixtures thereof, reacting a phosphorus acid ester of the following Formula (IV)
<Chemistry id="chema01" num="0001"><Image id="ia01" he="20" wi="58" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" /></Chemistry> wherein R<Sup>t</Sup> is aryl, R<Sup>2</Sup> is alkyl or aryl, with a hydrophilic polyoxyalkylene of the following Formulas (VIII), or (IX)
<Chemistry id="chema02" num="0002"><Image id="ia02" he="27" wi="81" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" /></Chemistry> wherein R<Sup>3</Sup> is alkyl with from about 1 to about 6 carbon atoms, and A is a hydrophilic polyoxyalkylene chain, and which reaction results in an intermediate compound Formulas (XI), (XII), or (XIII), wherein component (XI) results from the reaction of phosphorus ester (IV) with polyoxyalkylene (VIII); component (XII) results from the reaction of phosphorus ester (IV) with about two molecules of polyoxyalkylene (VIII), and component (XIII) results from the reaction of phosphorus ester component (IV) with polyoxyalkylene glycol (IX)
