Procedure

This intermediate was prepared by adding 256 parts of diethyl-N,N-bis(hydroxyethyl)aminomethyl phosphonate to a 14% by weight solution of sodium hydroxide in water in a stirred reactor equipped with a distillation column and heating the mixture slowly to cause distillation of by-product ethanol to begin. The column temperature was maintained at 72°-75° C. and the reactor temperature was maintained at 80° C. until distillation stopped. The pH of the cooled product was 10.1 and the percent solids was 51.7.
