Description

Applications
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.

Solubility
Soluble in water, carbon disulfide, ethanol, acetone and benzene. Slightly soluble in ethyl ether.

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