The Raw Material for The Production of Dimethyl Carbonate -- Vinyl Carbonate CAS 96-49-1¹

Preview:

Product Description Ethylene Carbonate(EC):Production method:Phosgene method: The direct reaction of ethylene glycol with phosgene is used to form chloroformyl glycol ester, and then neutralized with caustic soda, and finally vacuum distillation to obtain higher purity vinyl carbonate ester. However, because phosgene is highly toxic and causes serious pollution to the environment, it has been banned in developed countries.Transesterification: The transesterification reaction of diethyl carbonate or dimethyl carbonate and ethylene glycol under the action of catalyst, and then the reactant is distilled under reduced pressure to obtain vinyl carbonate.Ethylene oxide and carbon dioxide addition method: ethylene oxide and carbon dioxide addition reaction to prepare vinyl carbonate is a reaction of exothermic, volume reduction, low temperature, high pressure conditions are conducive to the reaction, while choosing the right catalyst is the key.Urea alcoholysis: under the catalysis of solid catalysts (such as dry basic zinc carbonate, zinc oxide and compound catalysts, etc.), ethylene carbonate is synthesized from urea and ethylene glycol. The reaction process is simple, the catalyst is easy to separate, and has high selectivity and conversion rate, and few side reactions.itemBattery level Industrial gradeappearanceColorless transparent liquid, no mechanical impuritiesContent, ≥99.99% 99.9% 99.7%Moisture, ≤0.005% 0.01% 0.05%Ethylene oxide content, ≤0.01% 0.01% 0.01%Ethylene glycol content ≤0.01% 0.01% 0.01%Chroma (aluminum - diamond), ≤10 10 10appearanceClear colorless liquid (> 35 ° C), crystalline solid at room temperatureFusing point35 to 38 oCBoiling point248oC/760mmHg, 243-244oC/740mmHgFlash point160 oCdensity1.3218Refractive index1.4158 (50oC)viscosity1.90mPa·s (40oC)Dielectric constant89.6Matters needing attention:Danger: flammable, water will produce carbon dioxide gas and ethanol, the process will produce a lot of heat, may cause explosion or combustion accidents, belongs to flammable and explosive substances.Storage and transportation: Should be stored in a cool, ventilated, dry place, away from direct sunlight, keep the container sealed, prevent volatilization or leakage. When transporting, it is necessary to choose the appropriate packaging materials, take effective anti-shock measures, and comply with the relevant transportation regulations.Use: When using, pay attention to wear protective equipment, such as gloves, masks, etc., away from fire and heat sources, and strictly follow the instructionsuse:Organic solvent: is a good performance of organic solvent, can be used to dissolve a variety of polymers, such as nitrocellulose, cellulose acetate and so on.Organic intermediate: can replace ethylene oxide for dioxylation reaction, is the main raw material for transesterification production of dimethyl carbonate, can also be used as a raw material for the synthesis of furazolidone.Battery field: It is an excellent solvent for lithium battery electrolyte, which can improve the cycle efficiency and safety of the battery.Other fields: It can be used as water glass slurry, fiber finishing agent, active intermediate for the production of lubricating oil and grease, and can also be used as a drawing liquid of acrylic fiber, nylon, etc., and can also be used as a stabilizer of plastic blowing agent and synthetic lubricating oil.Hunan Huahexing Chemical Trading Co., Ltd. is a large comprehensive economic entity integrating production and sales.
