Introduction |
White crystal, easy to absorb moisture and become unstable compound. Melting point 73.6 ℃. Boiling point 200 ℃ (decomposition). In the air, it can be slowly oxidized to phosphoric acid, when heated to 180 ℃ . it is broken down into phosphoric acid and phosphate Hydrogen (extreme toxic). When it is heated in 180-200 ° C (with the presence of oxygen ), it can be decomposed into phosphoric acid and phosphates in water and lower alcohols. It has strong hygroscopicity and deliquescence; corrosive matter |
Uses |
. It is mainly used in the plastics industry as reducing agent, nylon whitening agent, plastic temperature agent and synthetic fiber ; in pesticide industry, it is the main material of herbicides, fungicides and water stabilizer. |
