実験手順

In carrying out the process of this invention, the anhydrous sodium tripolyphosphate particles are moisturized with from about 145% to about 185% by weight of the theoretical quantity of water necessary to produce sodium tripolyphosphate hexahydrate. This range of added water is equivalent to from about 30% to about 35% water by weight based on the weight of the wet sodium tripolyphosphate, that is, the weight of the anhydrous sodium tripolyphosphate plus the added water. Preferably, the anhydrous sodium tripolyphosphate particles are moisturized with from about 145% to about 160% by weight of the theoretical quantity of water necessary to produce sodium tripolyphosphate hexahydrate. This preferred range of added water is equivalent to from about 30% to about 32% water by weight based on the weight of the wet sodium tripolyphosphate.
