Anhydrous sodium tripolyphosphate

摘要

A novel anhydrous sodium tripolyphosphate, well adapted for detergency applications, has an X-ray diffraction pattern essentially characterizing a phase I sodium tripolyphosphate; a viscosity, in aqueous medium, characterizing a phase II sodium tripolyphosphate; a rate of hydration characterizing a phase I sodium tripolyphosphate; and which exhibits an ROH at 1 minute of greater than about 90 DEG C.
