Carbonato de dimetilo DMC CAS 616-38-6

El DMC presenta una estructura molecular única que contiene grupos carbonilo, metilo y metoxi, lo que lo hace altamente reactivo.

Methylation & Carbonylation: It serves as a highly efficient methylating and carbonylating agent.

Green Substitute: Due to its low toxicity, DMC is widely used as a safe alternative to hazardous chemicals such as phosgene, dimethyl sulfate (DMS), and methyl chloride in various chemical synthesis processes.

Applications & Core Functions

DMC is a pivotal material across multiple industries, particularly excelling in the green energy and advanced chemical sectors:

• Lithium-Ion Battery Electrolytes (Green Energy): Acts as a crucial co-solvent in power storage and EV batteries. It effectively lowers the viscosity of the electrolyte, increasing the mobility of lithium ions and enhancing battery conductivity and discharge capacities.
• Polycarbonate (PC) Synthesis: Functions as a safe carbonylating agent, replacing highly toxic phosgene in the production of high-performance engineering plastics.
• Paints, Coatings & Adhesives: Serves as a fast-evaporating, green solvent replacing MEK, toluene, and ethyl acetate, improving the environmental compliance of the final products.
• Pharmaceutical & Agrochemical Intermediates: Acts as a methylating agent for the safe synthesis of anti-infectives, antipyretics, and advanced pesticides.

Requisitos del entorno de almacenamiento

• Temperatura y ambiente: Store in a cool, dry, and well-ventilated area, preferably outdoors or in a detached building. Keep ambient temperature below 30°C.
• Aislamiento: Keep strictly away from heat sources, sparks, open flames, and hot surfaces.
• Container Maintenance: Keep containers tightly closed and sealed until ready for use. Store away from strong oxidizing agents, acids, and bases.

Precauciones de manipulación y uso

• Safety Gear: Wear appropriate personal protective equipment (PPE), including safety goggles, chemical-resistant gloves, and protective clothing.
• Ventilación: Ensure adequate exhaust ventilation during handling to prevent vapor accumulation. Avoid inhalation of vapors or mists.
• Seguridad contra incendios: Due to its high flammability, always implement grounding and bonding measures for containers during product transfer to prevent static discharge. Use non-sparking tools.

Formulaciones

Formulation Example: Lithium-Ion Battery Electrolyte

• Typical Composition: Lithium Hexafluorophosphate (LiPF6) + Ethylene Carbonate (EC) + Dimethyl Carbonate (DMC) + Diethyl Carbonate (DEC).
• Role of DMC: In this formulation, high-dielectric solvents like EC are often highly viscous. DMC is formulated into the mix to sharply reduce the overall viscosity of the electrolyte. This ensures rapid ion transport, improves the low-temperature performance of the energy storage system, and stabilizes the solid electrolyte interphase (SEI) on the electrodes.
