CAS NO: 7664-38-2

Molecular Formula: P3O4 Molecular Weight: 98

characteristics: Colorless transparent sticky liquid, weight: 1.70, Soluble in water and release heat, high-temperature heating and dehydrate in pyrophosphoric acid and metaphosphoric acid, crystallization after longtime in the cold, Corrosive, easy hygroscopic, sealing preservation

physical property: Pure phosphate Acid is colorless crystals, Melting point 42.3℃, High boiling point acid, soluble in water with any ratio, Phosphoric acid reagent is sticky, non-volatile concentrated solution, Phosphoric Acid content 83%~98%, Phosphoric acid as the acid, acid stronger than carbonic acid, phosphoric acid and sodium carbonate reactions in different PH values, can generate different acid salt

 

Chemical properties and Industry production:

a kind of strength of ternary acid, Nonvolatile liquid, difficult to decompose, not acid oxidation, Since phosphoric acid is a ternary acid, the molecule has three hydrogen atoms can be ionized, so he can form a salt, two kinds of acid salts, such as with NaOH reaction, different Molar ratio generates different reaction products.

In industry, sulfuric acid reaction with the calcium phosphate to get phosphoric acid

Reduce calcium sulfate precipitation which slightly soluble in water, the filtrate is the phosphoric acid solution.

 

Usage:

Mainly used for phosphate industrial, electroplating, polishing industry, sugar industry, compound fertilizer, etc
