  • Solubility : Insoluble in water, but soluble in hot ethanol, benzene, ether, carbon tetrachloride, glacial acetic acid and other organic solvents.
• Chemical Properties: Diphenyl carbonate can be decomposed by hot alkali and has a certain chemical stability.
• Main Uses :
  • Polymer - material Synthesis: It is an important synthetic raw material for engineering plastics such as polycarbonate (PC), which is widely used in plastic products, optical materials, electronic materials and other fields.
  • Pesticide Field: It is mainly used in the synthesis of methyl isocyanate in pesticide production, and then used to prepare carbamate pesticides, such as carbofuran.
  • Plastic Industry: It is used to manufacture polyaryl carbonate, p - hydroxybenzoate polyester, aliphatic monoisocyanate, diisocyanate, etc., and can also be used as a plasticizer for plastics such as polyurethane and polyester, and as a solvent.
• Production Process: The traditional synthesis method of DPC uses phosgene and phenol as raw materials. However, phosgene is highly toxic and corrosive, so the non - phosgene method for synthesizing DPC has attracted much attention. At present, the non - phosgene methods for synthesizing DPC mainly include transesterification, urea alcoholysis, oxidative carbonylation, etc.
• Storage Conditions: It should be stored in a cool and dry place, away from fire and heat sources, and keep away from strong oxidants. Generally, the storage temperature can be 2 - 8°C, and it should be protected from light and moisture.
