Phthalic Anhydride

Product Description

Phthalic Anhydride (Other Names: Phthlandion Phthalicacidanhydride)
CAS No.: 85-44-9
MF: C8H4O3
Purity: 99.8%min

Specification:
Phthalic anhydride is the organic compound with the formula C8H4O3. This anhydride of phthalic acid, a colourless solid, is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. In 2002, approximately 4.6 billion kilograms were produced
Hydrolysis of anhydrides is not typically a reversible process. However, phthalic acid is easily dehydrated to form phthalic anhydride due to the creation of a thermodynamically favorable 5-membered ring.
