Product name:Potassium polymetaphosphate
CAS: 7990-53-6
Molecular Formula: (KPO3)n
Molecular Weight: 0
Product description:White fibrous crystal or powder. Odourless. Slowly dissolve in water, its solubility vary with polymerization degree, average of 0.004%. Alkaline solution. Soluble in sodium salt solution, can quickly dissolve in dilute mineral acids, insoluble in ethanol.Generally by the potassium dihydrogen phosphate heating to 400 ~ 700 ℃ (in theory can be heated to 200 ℃ or so) and maintained for several hours to do intramolecular dehydration condensation. The degree of polymerization of finished product take off in the heating temperature and time. In order to improve the degree of polymerization. Also a condensation in 850 ℃.
