Production methods
1 phosgene method raw material propylene glycol and phosgene action, the formation of chloroformic acid hydroxyl isopropyl ester, and then with sodium hydroxide action to generate propylene carbonate, and then by vacuum distillation products.
2. Transesterification.
3. Chloropropanol method.
4 propylene oxide and carbon dioxide synthesis method carbon dioxide and propylene oxide reaction at 150-160℃, 5MPa to form propylene carbonate. The finished product was obtained by decompression fractionation. The above methods have been industrialized, but the first three methods are more expensive to produce and the product is of poor quality, so they are gradually replaced by the fourth method.
5. Propylene oxidation and carbon dioxide synthesis. This method is a synthetic method developed in the laboratory in recent years.

Introduction to the
Cyclic carbonates include five - ring, six - ring, seven - ring carbonates and large - ring carbonates above seven - ring, of which propylene carbonate and vinyl carbonate are the most widely used Chemicalbook. Vinyl carbonate is an excellent polar high boiling point solvent and surfactant raw material, widely used in plastics, printing and dyeing, polymer synthesis, gas separation and electrochemistry and other fields.
Application field
Carbonic acid ester is a polar solvent, can be used as plasticizer, spinning solvent, water-soluble dyes and plastic dispersant, can also be used as oil solvent and olefins, aromatic extraction agent. Carbonate propylene battery electrolyte can withstand harsh light, heat and chemical changes. It is also used in geological beneficiation and analytical chemistry. In addition, propylene carbonate can replace phenolic resin as a wood binder, but also used in the synthesis of dimethyl carbonate.
Chemical properties
Colorless odorless flammable liquid. It is miscible with ether, acetone, benzene, chloroform, ethyl acetate, etc., soluble in water and carbon tetrachloride.
use
1. Carbonate used as oil solvent, spinning solvent, olefin, aromatic extraction agent, carbon dioxide absorbent, water-soluble dyes and pigment dispersant, etc
2. Carbonate can be used as a stationary solution and solvent for gas chromatography, as well as in the synthesis of polymer
3. Carbonates are UV-curable paints and inks
4. Carbonate is a polar solvent, used as plasticizer, spinning solvent, water-soluble dyes and plastic dispersant. Also can be used as oil solvent and olefins, aromatic extraction agent. Carbonate propylene battery electrolyte can withstand harsh light, heat and chemical changes. It is also used in geological beneficiation and analytical chemistry. In addition, propylene carbonate can replace phenolic resin as a wood binder, but also used in the synthesis of dimethyl carbonate.
5. Carbonates can be used as solvents for synthetic fibers and other polymers, as extractants, plasticizers, etc
6. Carbonate as a kind of efficient solvent, used to remove carbon dioxide in petroleum gas, petroleum cracking gas, oil field gas and synthetic ammonia feedstock gas, can also be used as plasticizer, spinning solvent or water-soluble dyes, pigment dispersant, oil solvent and olefins and aromatic extraction agent.
