Phthalic Anhydride

Product Description

What is Phthalic Anhydride?

Phthalic Anhydride (CHO) is an important industrial chemical compound, commonly used as a raw material in the manufacture of plasticizers, resins, dyes, and pharmaceuticals. It appears as a white crystalline solid and is derived through the catalytic oxidation of ortho-xylene or naphthalene.

With its versatile chemical properties, Phthalic Anhydride is a vital component across several industrial sectors, particularly in the production of phthalate plasticizers such as di(2-ethylhexyl) phthalate (DEHP) and polyester resins used in automotive and construction applications.

Applications of Phthalic Anhydride

Phthalic Anhydride is a cornerstone chemical in several industries. Its major uses include:

1. Plasticizer Manufacturing

Used in the production of phthalate esters, especially DOP (Di-Octyl Phthalate), which imparts flexibility to PVC and other plastics.

2. Alkyd Resin Production

Alkyd resins are key ingredients in paints, varnishes, and coatings, offering durability, gloss, and weather resistance.

3. Unsaturated Polyester Resins (UPR)

Widely used in fiberglass-reinforced plastics for applications such as automotive bodies, marine components, and storage tanks.

4. Pigments and Dyes

Acts as a precursor for anthraquinone dyes and pigments used in textiles and printing inks.

5. Pharmaceuticals and Agrochemicals

Intermediate in the synthesis of certain drugs, insect repellents, and agricultural chemicals.
