【Uses of Sodium Pyrophosphate】
1. Industrial Grade: Used as detergent, pharmaceutical and toothpaste stabilizer, water softener, boiler antiscaling agent, metal ion chelant, and also used in electroplating, electrolysis, plant fiber blenching, etc.
2. Food Grade: In food industry, used as quality improver, applied to can, fruit drinks, milk product, bean milk and so on. Tetra Sodium Pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing tetrasodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer.
【Production of Sodium Pyrophosphate】
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.
Alternatively, it can be created by the molecular dehydration of dibasic sodium phosphate at 500 °C (932 °F).
