Properties and Uses
Propylene carbonate (propylene glycol carbonate) is soluble in water and carbon tetrachloride, mixes with ether, acetone, benzene and other miscible, is a good polar solvent, nature is stable, non-toxic solvent, pure, no corrosion of carbon steel equipment, used for removal of natural gas, petroleum cracking gas, carbon dioxide and hydrogen sulfide in synthetic ammonia feed gas, is an ideal solvent, can also be used as plasticizer, spinning solvent or water solvent dye pigment dispersant, oily solvent and extracting agent of olefins and aromatics. Based on people's concern for resources and environmental problems and the social demand for sustainable development, green chemistry with the goal of eliminating pollution, making rational use of resources and achieving sustainable development has become the hot spot and frontier of current chemistry research. Many processes will be replaced by clean and environmentally friendly processes. The continuous promotion and application of dimethyl carbonate, polycarbonate and polyurethane in its downstream products will inevitably increase the market demand for propylene carbonate.
At present, the most important is used to remove carbon dioxide and hydrogen sulfide from natural gas, oil pyrolysis gas, oil field gas and synthetic ammonia conversion gas.In the electronic industry, it can be used as an excellent medium for high-energy batteries and capacitors, and as a solvent and plasticizer for polymers.
Propylene carbonate can also be used as an oil solvent and as an extraction agent for olefins and aromatics.In the textile industry can be used as synthetic fiber additives and fixatives, spinning solvents or water-solvent dye pigment dispersant; In addition, it is an extremely versatile organic synthesis of raw materials and intermediates.
