Procedure

A tetrakis(hydroxymethyl) phosphonium sulfate urea precondensate was prepared by refluxing 1200 gram of tetrakis(hydroxymethyl) phosphonium sulfate (86% solids), 500 grams of water and 75 grams of urea for 2 hours. The resulting solution was diluted with 1300 grams of water and 77 grams of sodium acetate was added thereto.
