Product Details

Phthalic anhydride is currently widely used in industrial sectors such as chemical, pharmaceutical, electronics, agriculture, coatings, and fine chemicals. Phthalic anhydride in China is mainly used for the production of phthalate plasticizers, accounting for about 60% of the total consumption of phthalic anhydride, 25% for dyes and paints, and about 15% for unsaturated resins and other products. Phthalic anhydride is an important organic chemical raw material, mainly used in the production of plastic plasticizers, alkyd resins, dyes, unsaturated resins, as well as certain pharmaceuticals and pesticides.
