Product Info

Product Details:

phthalic anhydride is a toxic, white crystalline compound used in the manufacture of phthaleins and other dyes, resins, plasticizers, and insecticides.

Phthalic anhydride is the anhydride of phthalic acid. This colorless solid is an important industrial chemical, especially for the large–scale production of plasticizers for plastics. It is presently obtained by catalytic oxidation of ortho–xylene or naphthalene. Phthalic anhydride can also be prepared from phthalic acid.

Phthalic anhydride is a versatile intermediate in organic chemistry, in part because it is bifunctional and readily available. The primary use of phthalic anhydride (PA) is as a chemical intermediate in the production of plasticizers from polyvinyl chloride (PVC).

Application :

The primary use of TCC’s phthalic anhydride (PA) is as a chemical intermediate in the production of plastics from vinyl chloride. Phthalate esters that function as plasticizers are derived from phthalic anhydride. Phthalic anhydride has another major use in the production of polyester resins and other minor uses in the production of alkyd resins used in paints and lacquers, certain guys, insect repellents, and urethane polyester polyols.

One of the main uses of phthalic anhydride is the production of “phthalate” plasticizers such as Vestinol 9 DINP (DiIsoNonyl Phthalate) which are used to produce flexible PVC (Vinyl) products. These include, but are not limited to Wire & Cable applications, coated fabrics, roofing membranes and swimming pool liners.
