Product Description Propylene carbonate, also known as propyllidene carbonate, propylene glycol carbonate, 1, 2-propylene glycol carbonate, 4-methyl-2, 5-dioxopentyclo-1-one.Preparation method:Propylene oxide and carbon dioxide synthesis method: The industry mainly uses propylene oxide and carbon dioxide under a certain pressure addition, and then vacuum distillation. Reaction conditions are generally 150-160oC, about 5MPa, the method has a high atomic utilization rate and is more environmentally friendly.Phosgene method: the raw material propylene glycol and phosgene action, the formation of chloroformate hydroxyl isopropyl ester, and then with sodium hydroxide to produce propylene carbonate, and then the vacuum distillation of the finished product, but phosgene is highly toxic, the environment and equipment requirements are high, gradually eliminated.Transesterification method: dimethyl carbonate or diethyl carbonate is prepared by transesterification reaction with propylene glycol, but this method has many reaction steps and high cost.Chloropropanol method: First, chloropropanol reacts with sodium carbonate to form propylene oxide, and then reacts with carbon dioxide to form propylene carbonate. This method is complex and costly.itemBattery grade Industrial gradeappearanceColorless transparent liquid, no mechanical impuritiesContent, ≥99.99% 99.9% 99.7%Moisture, ≤0.005% 0.01% 0.05%Propylene oxide content, ≤0.01% 0.01% 0.01%Propylene glycol content, ≤ 0.01%0.01% 0.01% 0.01%Density (20%),g/ml 1.2±0.005 1.2±0.005 1.2±0.005Chroma (aluminum - diamond),≤ 10 10 10Packing, storage and transportation:Galvanized or painted iron drum packing, net weight 250kg per barrel, can also be used IBC, TANK truck or ISO TANK; Storage warehouse ventilated, away from open flame, high temperature, separate from oxidizer.English namePropylene carbonate, PC for shortCAS108-32-7.Molecular formulac4h6o3Molecular weight102.09.appearanceColorless transparent liquid.Fusing point-48.8oC or -49 oC.Boiling pointAround 242oC.Relative density1.2047 (20/4 ° C).Refractive index1.4218.Flash pointGreater than 230oC or 123oC.solubilityIt can be miscible with ether, acetone, benzene, chloroform, vinyl acetate, etc., and soluble in water and carbon tetrachloride.Safety information:Hazard: Propylene carbonate is flammable and irritating. May be harmful to the body if inhaled, ingested or absorbed through the skin, may be irritating to the eyes and skin.Emergency treatment: After skin contact, remove contaminated clothing immediately and rinse thoroughly with soapy water and clean water; After eye contact, open the upper and lower eyelids immediately, rinse with running water for 15 minutes, and seek medical attention. After inhalation, leave the scene immediately to a place with fresh air, and seek medical attention; After ingestion, gargle with water, drink enough warm water, induce vomiting, and seek medical attention.Product use:It is used in the electronics industry for the production of lithium battery and capacitor electrolytes as plasticizers, spinning solvents, water-soluble fuels and dispersants for plastics.It is used to remove carbon dioxide from petroleum gas, petroleum cracking gas, oil field gas and synthetic ammonia feedstock gas, and is used to synthesize dimethyl carbonate.Hunan Huahexing Chemical Trading Co., Ltd. is a large comprehensive economic entity integrating production and sales.
