Product Description

CAS 1314-56-3 Phthalic Anhydride White Powder For chemical Intermediate

Phosphoric anhydride Description:

It is usually white, highly deliquescent crystalline powder. Density: 0.9g/cm3, sublime at 300°C.

M.P.: 580-585°C. Vapor tension: 133.3Pa (384°C). It will become vitreous body when heated at high

temperature under pressurization. It can easily absorb moisture in the air; will release white fume when

dissolving in the water.
