Polyphosphoric acid 105%-115% (PPA)
Polyphosphoric acid (PPA)
Chemical formula: Hn+2PnO3n+1
CAS No.: 8017-16-1
Executive standard: HG-T4691-2014
Appearance: Colorless viscous liquid, easy to absorb moisture, corrosive, and produce orthophosphoric acid after being melted and hydrolyzed with water.
It is easy to crystallize, and the crystal form can be heated and melted without affecting the quality
Uses: Multi-purpose chemical intermediate products, widely used in medicine, perfume, leather, chemical industry and other industries, used as compound cyclizing agent, acylating agent and dehydrating agent in organic synthesis, as catalyst in petroleum industry. High-grade feed additives, fabric flame retardant and anti-static, its value lies in its high dehydration ability. Its polyols are important surfactants, temperature-resistant lubricants and fire retardants. Polyphosphoric acid is a high-concentration phosphoric acid, with low corrosiveness and enhanced production process. It is widely used in high-efficiency phosphate fertilizers, polyphosphate products and organic catalysts. It is a higher-level product of ordinary phosphoric acid.
Packaging: The conventional packaging is IBC barrel, the capacity of each barrel is 1650--1700KGS
·Special content between 95%--115% can be customized
