Tetra Sodium Pyrophosphate(TSPP)
Byname: Tetra Sodium pyrophosphate
Molecular formula: Na4P2O7
Molecular Weight: 265.9
Standard executed: HG/T2968-1999(Technical Grade)
GB8848-88(Food Grade)
CAS Number: 7722-88-5
Properties:
White powder; Soluble in water but insoluble in ethanol; Relative density 2.45g/cm3and melting point 890℃; Deliquescent in the open air. Its aqueous solution shows weak alkalinity and is stable at 70 ℃ but will be hydrolyzed into di-sodium phosphate when boiled
Uses:
Applied in industries of detergents as detergent auxiliary, paper production to bleach and electroplating; In food industry it is used as buffering agent, emulsifier, nutrition ingredients and quality improver.
Packing and storage:
In 25kg,50kg,1000kg net bage,store at a cool,dry and well ventilated place.
