乙烯碳酸酯(ethylene carbonate,简称EC)是一种环状有机碳酸酯化合物,化学式为C₃H₄O₃,常温下为无色透明液体或低熔点固体。以下是其详细解析:
乙烯碳酸酯分子结构由乙烯基与碳酸酯基团结合形成五元环,分子式为: $$ ce{O=C(OCH2CH2O)} $$ 其熔点为36-38°C,沸点243°C,可溶于水、乙醇等极性溶剂,但不溶于非极性溶剂。该化合物具有高热稳定性和高介电常数(89.6),使其成为锂离子电池电解液的关键组分。
乙烯碳酸酯属于低毒类物质,但高温分解可能释放一氧化碳。实验研究表明,其对水生生物无明显急性毒性(来源:欧洲化学品管理局ECHA数据库)。
Ethylene carbonate(碳酸亚乙酯)是一种有机化合物,以下是其详细解释:
其英文名称“Ethylene carbonate”中的“ethylene”指乙烯基,“carbonate”表示碳酸酯结构。更多技术参数可参考物竞化学品数据库(来源6)或生工生物产品说明(来源3)。
