A solvent- and halogen-free synthesis of high purity triflate ionic liquids via direct alkylation of organic bases (amines, phosphines or heterocyclic compounds) with methyl and ethyl trifluoromethanesulfonate (methyl and ethyl triflate) has been developed. Cheap and non-toxic dimethyl and diethyl carbonate serve as source for the methyl and ethyl groups in the preparation of methyl and ethyl triflate by this invented process. The properties of ionic liquids containing the triflate anion are determined and discussed.
通过直接用甲基三氟甲烷磺酸酯（甲基三氟甲磺酸酯）和乙基三氟甲烷磺酸酯（乙基三氟甲磺酸酯）烷基化有机碱（胺、膦或杂环化合物），开发了一种无溶剂和卤素的高纯度三氟甲磺酸酯离子液体的合成方法。在该发明过程中，廉价且无毒的碳酸二甲酯和碳酸二乙酯作为甲基和乙基三氟甲磺酸酯制备过程中甲基和乙基的来源。确定并讨论了含三氟甲磺酸根阴离子的离子液体的性质。
