Procedure

Disodium orthophosphate dihydrate was prepared by a conventional rotary process. Phosphoric acid, sodium carbonate and water were reacted together to give a sodium orthophosphate solution having a molar ratio of sodium to phosphorus of 2/1 and a density of 50° C. baume at 100° C. The resulting solution was then evaporated to dryness in a rotary dryer and the dried product then cooled and screened to separate a -20 +100 mesh granular DSP.Duo product.
