Activity Description
The production activities of this product include raw material input, oxidation reaction, cooling and condensation, product collection, exhaust gas treatment and other processes.
Process Description
Phosphorus pentoxide, chemical formula: P2O5, CAS number: 1314-56-3, is a pure white powdery solid. When the purity is insufficient, it becomes a yellow powder with a special pungent odor. Phosphorus pentoxide is hygroscopic and will quickly absorb moisture in the air and deliquesce when exposed to the air. Phosphorus pentoxide is often used as a desiccant and dehydrating agent, and is also the main material in the manufacture of phosphoric acid, pesticides, and phosphates.

Technology comment
In the phosphorus pentoxide generator, phosphorus reacts with oxygen to produce gaseous phosphorus pentoxide. Excess dry cold air is introduced into the generator to quickly cool the gaseous phosphorus pentoxide, causing it to condense into a solid and settle into the screw conveyor at the bottom of the generator, thereby collecting the product. For tail gas generated when collection is incomplete, the phosphorus pentoxide reacts with water for tail gas absorption. The main chemical reaction equation is: P4+5O2=2P2O5.
