CAS 1314-56-3 Phthalic Anhydride P2O5 White Solid Crystalline Industrial Reagent 

Chemical formula: P2O5

Molecular weight: 141.94

Properities: 

Easily deliquescent white crystalline powder, relevant density is 0.9g/cm3, sublimate at 300℃,

melting point is 580-585℃, vapour pressure is 133.3 Pa (384℃). When heating to higher

temperature, the crystalline changes to amorphous vitreum, absorbing moisture when expose

to the air. omitting heat and white smoke when soluble in water.
