| SODIUM TETRAPHOSPHATE Chemical Properties |
| SODIUM TETRAPHOSPHATE Usage And Synthesis |
Chemical Properties | Na6P4O13 ? H2O . Formula weight of the anhydrous salt is
469.85. The crystalline salt cannot be obtained. On standing for
four weeks, the dried oil is partially transformed to Na3HP2O7 .
H2O. Heating of this mixture to 200°C for two hours produces a
quantitative yield of Na3HP2O7. | Synthesis | Hexasodium tetraphosphate is formed by careful hydrolysis of
sodium tetrametaphosphate(method of Thilo and Ratz):
![SODIUM TETRAPHOSPHATE synthesis SODIUM TETRAPHOSPHATE synthesis](/NewsImg/2024-07-10/6385620033906537544361481.png) A solution of 4.8 g. of Na 4 P4 O 12 ? 4H2O in 85 ml. of hot water
is prepared, and after cooling, a solution of 0.8 g. of NaOH in
some water is added. The mixture is kept over H2SO4 in a vacuum
desiccator, placed in an oven at 40°C. The rat e of evaporation should be such that after about 100 hours no less than 8 to 10 ml.
remains. The solution is then diluted to 30 ml. and acetone is
added. The colorless oil formed is dissolved in some water and
reprecipitated with acetone.
