Phthalic anhydride is an important industrial chemical that has a very wide range of applications. Phthalic anhydride (PA) is often used to make unsaturated polyester resins (UPR), which are used in industries such as electronics and construction automotive parts. Phthalic anhydride is used as a raw material for DBP and DOP plasticizers, and is also used to make dyes. As a professional phthalic anhydride supplier, Douwin Chemical has high quality phthalic anhydride for sale.
Phthalic anhydride is a white organic compound with a pungent odor, which is soluble in water, alcohols and other organic solvents. Phthalic anhydride should be stored in sealed containers in a cool and dry place and kept away from water, acids, strong oxidizing agents, alcohols and amines. Phthalic anhydride is irritating to the skin and eyes and may cause allergic dermatitis or damage to the cornea and conjunctiva. Therefore, workers should wear appropriate personal protective equipment when working with phthalic anhydride.
