Phtalic Anhydride--Dye Intermediate

Jun 08, 2016

Product Description

Introduction: 

1. 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 

2. Applications in industry and organic synthesis 
Phthalic anhydride is a versatile intermediate in organic chemistry, in part because it is bifunctional and cheaply available. It undergoes hydrolysis and alcoholysis. Hydrolysis by hot water forms ortho-phthalic acid. This process is reversible.
