Main Characteristic of Phthalic Anhydride :
1.Phthalic anhydride is the organic compound with the formula C6H4(CO)2O. It is the anhydride of phthalic acid.
Phthalic anhydride is a principal commercial form of phthalic acid.
2. It was the first anhydride of a dicarboxylic acid to be used commercially.
3.This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers
for plastics.
