摘要 |
A process is provided for preparing a salt of a hydroxy-substituted ester of phosphoric acid, comprising: (a) reacting a phosphate diester with an alkylene oxide, (b) reacting the product mixture of step (a) with a phosphating agent; and (c) reacting the product mixture of step (b) with an amine; wherein the phosphate diester is reacted with the alkylene oxide of step (a) in the substantial absence of a phosphate monoester.
