1. Vinyl carbonate: molecular formula: C3H4O3
Transparent colorless liquid (>35 ℃), crystalline solid at room temperature. Boiling point: 248 ℃/760mmHg, 243-244 ℃/740mmHg; Flash point: 160 ℃; Density: 1.3218; Refractive index: 1.4158 (50 ℃); Melting point: 35-38 ℃; This product is a good solvent for polyacrylonitrile and polyvinyl chloride. It can be used as spinning liquid on textile; It can also be directly used as a solvent for removing acid gas and an additive for concrete; It can be used as pharmaceutical components and raw materials in medicine; It can also be used as plastic foaming agent and stabilizer of synthetic lubricating oil; In the battery industry, it can be used as an excellent solvent for lithium battery electrolyte
2. Propylene carbonate molecular formula: C4H6O3
Colorless and odorless, or light yellow transparent liquid, soluble in water and carbon tetrachloride, and miscible with ether, acetone, benzene, etc. It is an excellent polar solvent. This product is mainly used in polymer operation, gas separation process and electrochemistry. Especially, it can be used to absorb carbon dioxide from natural gas and synthetic ammonia raw materials of petrochemical plants, and also can be used as plasticizer, spinning solvent, olefin and aromatic extraction agent, etc.
Toxicological data: No poisoning was found after oral administration or skin contact in animal experiments Rat oral LD50=29,000 mg/kg
This product should be stored in a cool, ventilated, dry place, away from fire sources, and stored and transported according to the general low toxic chemicals regulations.
3. Diethyl carbonate Molecular formula: C5H10O3
Colorless liquid with slight odor; Steam pressure 1.33kPa/23.8 ℃; The flash point is 25 ℃ (flammable liquid can volatilize into vapor and run into the air. The volatilization is accelerated when the temperature rises. When the mixture of volatile vapor and air contacts with the fire source and can flash sparks, this short burning process is called flash, and the lowest flash temperature is called flash point. The lower the flash point, the greater the risk of fire.); Melting point - 43 ℃; Boiling point 125.8 ℃; Solubility: insoluble in water, miscible in most organic solvents such as alcohol, ketone and ester; Density: relative density (water=1) 1.0; Relative density (air=1) 4.07; Stability: stable; Hazard sign 7 (flammable liquid); Main applications: used as solvent and organic synthesis
