용도 및 제조
Uses
Used in food production (sequestrant, emulsifier, and buffer), dyeing (mordant), manufacturing (enamels, ceramics, detergents, and boiler compounds) and fireproofing; Also used in weighting silk, tanning, soldering and brazing (instead of borax), and medicine (cathartic); [Merck Index]
Brazing [Category: Heat or Machine]
응용 분야
용도Buffering agent.
제조 방법
생산 방법Either bone phosphate (bone ash), obtained by heating bones to whiteness, or the mineral phosphorite is used as a source of tribasic calcium phosphate, which is the starting material in the industrial production of dibasic sodium phosphate. Tribasic calcium phosphate is finely ground and digested with sulfuric acid. This mixture is then leached with hot water and neutralized with sodium carbonate, and dibasic sodium phosphate is crystallized from the filtrate.
