Potassium tripolyphosphate Use and Manufacturing

Methods of Manufacturing

Commonly used production methods are polycondensed phosphoric acid one-step method and thermal phosphoric acid two-step method. Thermal Phosphoric Acid Two-Step Process Refer to industrial potassium tripolyphosphate, the difference is that arsenic removal agent and heavy metal removal agent are added for solution purification, and impurities such as arsenic and heavy metals are filtered out.

Uses

Tissue improver; chelating agent; emulsifier; buffer; stabilizer; water treatment agent.

Intermediates

Production

100,000 - 500,000 lb
