Neutral potassium iodide reagent containing 13.61 g potassium dihydrogen-phosphate, 14.2 g anhydrous disodium hydrogen phosphate and 20.0 g potassium iodide in each 1000 mL of solution. 

Buffered anifine. Dissolve 11.4g anhydrous disodium hydrogen phosphate and 4.4g citric acid in 800ml H2O. Add 3 ml aniline and 200ml 95% ethanol. Mix and add 0.5 ml Brij-35 (Fisher, Pittsburgh, PA). 

The two-stage process involves dehydration of a concentrated monophosphate solution to produce anhydrous disodium hydrogen phosphate, which is then converted to sodium pyrophosphate in a rotary kiln. The process used for the production of STTP can typically be used for sodium pyrophosphate.

Sodium phosphites.—Disodium hydrogen phosphite, Na2HP03,5H20, is obtained by concentration of a solution of phosphorous acid neutralized with sodium carbonate, and over sulphuric acid changes to the anhydrous salt. The pentahydrate is very deliquescent. The anhydrous salt melts at 53° C., and above this temperature is oxidized to sodium phosphate, with evolution of phosphine.7 The heat of formation from the elements is 285 1 Cal.,8 and from the acid and sodium hydroxide in solution 28 45 Cal.9 The heat of hydration of the anhydride to the pentahydrate is 18 7 Cal.
