Product Applications

UV curing coating and ink; Used as stationary liquid and solvent of gas chromatography, and also used in the synthesis of polymer; Used as oily solvent, spinning solvent, olefin, aromatic extraction agent, carbon dioxide absorbent, dispersant of water-soluble dyes and pigments, etc.; This product is a polar solvent and is used as plasticizer..

Production method

1. Propylene glycol, the raw material of phosgene method, acts with phosgene to generate hydroxyisopropyl chloroformate, then acts with sodium hydroxide to generate propylene carbonate, and then distills under reduced pressure to obtain the finished product. 2. Transesterification. 3. Chloropropyl alcohol method. 4. Synthesis of propylene oxide and carbon dioxide carbon dioxide and propylene oxide react at 150-160℃ and 5MPa to form propylene carbonate. The finished product is obtained by vacuum distillation. The above methods have been industrialized, but the first three methods have high production costs and poor product quality, so they are gradually replaced by the fourth method. 5. Propylene oxidation and carbon dioxide synthesis. This method is a synthetic method developed by the laboratory in recent years.
