Product Description

Phthalic anhydride(PA) is the anhydride of phthalic acid.It isWhite acicular crystal, flammable, easily sublimed below boiling point, with a slight odor. The relative density is 1.527. Melting point 131.6ºC. Boiling point 295ºC (sublimation). Flash point (open cup) 151.7ºC. Ignition point 584ºC. Slightly soluble in hot water and ether, soluble in ethanol, benzene and pyridine.
It is presently obtained by catalytic oxidation of ortho-xylene or naphthalene. Phthalic anhydride can also be prepared from phthalic acid.It is a versatile intermediate in organic chemistry, The primary use of phthalic anhydride is as a chemical intermediate in the production of plasticizers from polyvinyl chloride.
The content of Maleic Anhydride less than 0.01%
