Propylene carbonate (molecular formula: C4H6O3) is a colorless and odorless flammable liquid. Soluble with ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. The ability to absorb carbon dioxide is strong and its properties are stable. In industry, it is obtained by adding epoxy propane and carbon dioxide under a certain pressure, and then vacuum distillation. It can be used as an oil based solvent, spinning solvent, olefin, aromatic hydrocarbon extractant, carbon dioxide absorber, and dispersant for water-soluble dyes and pigments.

Purpose:
In the electronic industry, it can be used as an excellent medium for high-energy batteries and capacitors. In the polymer industry, it can be used as a solvent and plasticizer for polymers. A plasticizer used as an adhesive and sealant. It can also be used as a curing accelerator for phenolic resin and a dispersant for water-soluble adhesive pigments and fillers. The chemical industry is the main raw material for synthesizing dimethyl carbonate and can also be used to remove carbon dioxide and hydrogen sulfide from natural gas and petroleum cracking gas· In addition, it can also be used in industrial fields such as textiles, printing and dyeing. Packaging: 200 kilograms of galvanized iron drums can also be packaged according to customer requirements. Storage and transportation should be stored in a cool, dry, and well ventilated place. Steel cylinders should be placed vertically to avoid heat and exposure to sunlight.
