용도

Phthalic anhydride is used in the preparation of primary amines. It is used as a precursor to prepare anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein and xanthene dyes. It serves as an important intermediate in the plastics industry, dyes, resins and pigments. It is used as a monomer for synthetic resins such as glyptal, alkyd resins and polyester resins. It plays a vital role in the large-scale production of plasticizers for plastics. Further, it acts as a curing agent for epoxy resins, anti-scaling agents, plating agents, surface treating agents, ion exchange agents, paint additives, adhesives, sealant chemicals and potential antibacterial agent.

참고

Moisture sensitive. Incompatible with strong oxidizing agents, strong bases, strong reducing agents and strong acids.

For examples of formation of phthalimides from amines, see: Org. Synth. Coll., 4, 106 (1963); 5, 973 (1973). As an alternative to hydrazinolysis, ɑ-amino acids can also be quantitatively recovered from their phthaloyl derivatives by prolonged reaction with aqueous methylamine at room temperature: Can. J. Chem., 48, 3572 (1970).

Can be used for the dehydration of nitro aldols to nitroalkenes; see, e.g.: Org. Synth. Coll., 7, 396 (1990).

Reaction with H2O2 gives monoperphthalic acid, useful in peroxidation reactions; see, e.g.: Org. Synth. Coll., 3, 619 (1955); 5, 805 (1973). With urea hydrogen peroxide, provides a superior system for converting N-heteroaromatics and tert-amines to their N-oxides: Chem. Ber., 125, 1965 (1992)
