摘要:这项发明涉及一种n-甲基-N-三甲基硅基三氟乙酰胺(n-Methyl-N-Trimethylsilyl Trifluoroacetamide)(mstfa)的合成方法,由此合成的mstfa,以及包含它的锂二次电池电解液.该发明涉及使用三氟乙酸乙酯(ethyltrifluoroacetate)和甲胺(methylamine)制备n-甲基三氟乙酰胺(n-Methyltrifluoroacetamide)的步骤,以及将三甲基氯硅烷(trimethylsilyl Chloride)加入到n-甲基三氟乙酰胺(n-Methyltrifluoroacetamide)和三乙胺(triethylamine)混合物中,从反应混合物中分离沉淀物以获得mstfa的步骤.根据本发明,可以通过分馏来相对容易地去除未反应的起始物质和副反应物,从而获得99.0%以上的高纯度mstfa,并且当将99.0%以上的高纯度mstfa用作锂二次电池电解液的添加剂时,可以提高锂二次电池的寿命特性.
