HOW TSPP (TETRASODIUM PYROPHOSPHATE) WORKS:
TSPP (Tetrasodium pyrophosphate) works as a water softener, and an emulsifier to protect clothes fibre from fading.
TSPP (Tetrasodium pyrophosphate) permits dirt and oil to be removed from clothing and prevents it from being redeposited in the wash.

PRODUCTION of TSPP (TETRASODIUM PYROPHOSPHATE):
TSPP (Tetrasodium pyrophosphate) is produced by the reaction of furnace-grade phosphoric acid with sodium carbonate to form disodium phosphate, which is then heated to 450 °C to form tetrasodium pyrophosphate:
2 Na2HPO4 → Na4P2O7 + H2O

PREPARATION OF TSPP (TETRASODIUM PYROPHOSPHATE):
TSPP (Tetrasodium pyrophosphate) is formed when pure disodium hydrogen orthophosphate is heated to 500℃ for 5 hours.
TSPP (Tetrasodium pyrophosphate) will contain better than 98 per cent Na4P2O7.
Crystalline masses large enough for optical measurements are produced by heating in platinum to above the melting point of the TSPP (Tetrasodium pyrophosphate), 800°, and cooling slowly.
Higher temperatures or longer heating times do not change the TSPP (Tetrasodium pyrophosphate), as this is the final product in the dehydration of disodium hydrogen orthophosphate.

HOW TSPP (TETRASODIUM PYROPHOSPHATE) MADE:
TSPP (Tetrasodium pyrophosphate) can be prepared by molecular dehydration of dibasic sodium phosphate at 500°C.
Sodium phosphates are generally prepared by the partial or total neutralization of phosphoric acid using sodium carbonate or sodium hydroxide.
Crystals of a specific hydrate can then be obtained by evaporation of the resultant solution within the temperature range over which the hydrate is stable.
Another way to prepare TSPP (Tetrasodium pyrophosphate) involves the calcination of sodium tripolyphosphate and a sodium salt.
