Propylene carbonate (molecular formula: C4H6O3) is a colorless, odorless, flammable liquid. Miscible with ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. It has a strong ability to absorb carbon dioxide and is stable in nature. In industry, it is obtained by adding propylene oxide and carbon dioxide under a certain pressure, and then distilling under reduced pressure. It can be used as oily solvent, spinning solvent, olefin, aromatic hydrocarbon extractant, carbon dioxide absorber, dispersant for water-soluble dyes and pigments, etc. Application 1. It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry. 2. In the polymer industry, it can be used as a solvent and plasticizer for polymers. 3. Used as a plasticizer for adhesives and sealants. 4. It can also be used as a phenolic resin curing accelerator and a dispersant for water-soluble adhesives, pigments and fillers. 5. The chemical industry is the main raw material for synthesizing dimethyl carbonate. It can also be used to remove carbon dioxide and hydrogen sulfide from natural gas and petroleum cracking gas. 6. It can also be used in textile, printing and dyeing and other industrial fields.
