Diphenyl carbonate

Diphenyl carbonate (CAS 102-09-0), commonly abbreviated as DPC, is a key monomer and reagent used across polymer synthesis, pharmaceutical manufacturing, and specialty chemical production.

Where is Diphenyl carbonate used?

• Polycarbonate production: reacts with bisphenol A via melt transesterification to produce engineering-grade polycarbonates without phosgene
• Polycarbonate diol and polyurethane manufacturing: builds aliphatic carbonate segments that improve hydrolytic stability in final polymer products and coatings
• Pharmaceutical and agrochemical synthesis: carbonate transfer reagent for carbamates, carbonates, and other active intermediates
• Fragrance and flavor applications: low-level fixative and esterification intermediate
• It functions as a carbonylating agent and transesterification reagent, enabling solvent-free and phosgene-free reaction pathways.

Commercial specifications

• Molten bulk for large-volume polymer-grade supply
• Standard grades: technical and high-purity polymer-grade
