General description
Phthalic anhydride is an anhydride of phthalic acid and a key intermediate in the production of plasticizers, dyes, polyesters resins, modifiers for rubber, and polymers.
Application
Phthalic anhydride may be used as a reactant in the preparation of N-substituted phthalimides, poly(isothianaphthene) and methyl (S)-2-phthalimido-4-methylthiobutanoate.
