Potassium Polymetaphosphate (KPMP)

Chemical formula : (KPO3)n

Molecular weight: 118.07

CAS Number: 7790-53-6

EINECS No.: 232-212-6


Properties

Highly polymerized linear-chain polyphosphates, there may be a small amount of cyclic structure of potassium trimethenate and ring structure of potassium tetrametaphosphate. It is a colorless to white glass-like block or sheet, or a white fibrous crystal or powder. Odorless. Slowly dissolved in water, its solubility varies with the degree of polymerization, generally 0.004%. The aqueous solution is alkaline. Soluble in sodium salt solution, rapidly soluble in dilute inorganic acids, insoluble in ethanol.

Application

Used as Moisture retention agents, leavening agents, acidity regulators, stabilizers, coagulants, anti-caking agents. It is used for moisture retention agents, leavening agents, acidity regulators, stabilizers, coagulants, anti-caking agents
