How to use
Phthalic anhydride, also known as phthalic anhydride, is an important organic chemical raw material used in a wide range of industries. It is mainly used in the production of PVC (polyvinyl chloride) plasticizers such as dioctyl phthalate (DOP) and dibutyl phthalate (DBP), which increase flexibility and processability in plastic products. Other major uses of phthalic anhydride include the manufacture of unsaturated polyester resins, alkyd resins, dyes, coatings, pesticides and pharmaceutical products
