It has a high dielectric constant (\u03b5 = 90 at 25 \u00b0C), which enables efficient dissociation of lithium salts (e.g.,\u00a0LiPF<sub>6<\/sub>,\u00a0LiBF<sub>4<\/sub>) into conductive ions. When mixed with low-viscosity co-solvents (e.g., DMC, ethyl methyl carbonate (EMC)), it improves electrolyte conductivity, thermal stability, and cycle performance of batteries. Widely used in consumer electronics, electric vehicles, and energy storage systems.<\/p>\n<p><strong>Chemical Synthesis Intermediate:<\/strong> Serves as a green methylating agent and carboxylating agent, replacing toxic reagents such as dimethyl sulfate and phosgene. It is used in the synthesis of pharmaceuticals, pesticides, and fine chemicals, including anti-inflammatory drugs, herbicides, and polycarbonate oligomers.<\/p>\n<p><strong>Industrial Solvent &amp; Plasticizer:<\/strong> As a high-boiling-point, low-VOC solvent, EC is used in coatings, inks, and adhesives, improving the solubility of resins and pigments and reducing environmental pollution. It also acts as a plasticizer for cellulose acetate and polyvinyl chloride (PVC), enhancing the flexibility and processability of polymer materials.<\/p>\n<p><strong>Gas Separation Solvent:<\/strong> Excellent solubility for polar acidic gases (e.g.,\u00a0CO<sub>2<\/sub>,\u00a0H<sub>2<\/sub>S) makes EC an ideal solvent for natural gas purification and flue gas treatment. It selectively absorbs acidic impurities, improving gas quality and reducing greenhouse gas emissions.<\/p>\n<p><strong>\u0414\u0440\u0443\u0433\u0438\u0435 \u0432\u0438\u0434\u044b \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u044f:<\/strong> Applied as a humectant in cosmetics and personal care products; used as a cross-linking agent in the production of polyurethanes; and serves as a heat transfer fluid in high-temperature industrial systems.<\/p>","protected":false},"excerpt":{"rendered":"<p>Ethylene Carbonate, commonly abbreviated as\u00a0EC, is a colorless, odorless, crystalline solid at room temperature, belonging to the cyclic carbonate family.
