Phthalic Anhydride

Description

What is Phthalic Anhydride?

Phthalic Anhydride is an organic compound with the chemical formula C₆H₄(CO)₂O, widely recognized as the anhydride of phthalic acid. It appears as a white crystalline solid and is one of the most important industrial chemicals used as a chemical intermediate. Phthalic Anhydride is primarily used in the production of plasticizers, polyester resins, alkyd resins, and dyes. With a global production volume of millions of tonnes annually, it plays a vital role in industries such as plastics, coatings, textiles, and chemicals.

Chemex Chemicals is one of the leading importers and suppliers of Phthalic Anhydride in India, offering high-purity products that meet stringent international quality standards.

Key Applications of Phthalic Anhydride

1. Plasticizers Production

• Used extensively in the manufacture of phthalate esters, which act as plasticizers.

• These plasticizers are essential for flexible PVC products such as pipes, hoses, cables, footwear, leather cloth, and packaging films.

2. Polyester Resins

• Serves as a major raw material in the production of unsaturated polyester resins.

• These resins are widely used in fiberglass-reinforced plastics, construction materials, automotive parts, and marine applications.

3. Alkyd Resins in Paints & Coatings

• Used in the manufacture of alkyd resins, which are key components in paints, varnishes, and lacquers.

• Enhances adhesion, durability, and resistance to chemicals in coatings.

4. Dyes and Pigments

• An intermediate in the production of anthraquinone dyes, phthalein dyes, rhodamine, fluorescein, xanthene dyes, and phthalocyanine pigments.

• Widely used in textiles, inks, and coatings.

5. Polyester Polyols & Polyurethanes

• Plays an important role in producing polyester polyols, which are further used in polyurethane foams, elastomers, and coatings.

6. Other Applications

• Functions as a rubber scorch inhibitor and retarder in rubber processing.

• Used in the production of insect repellents and specialty chemicals.
