【摘要】 采用乙腈探针法和吡啶探针法测定了离子液体的酸性,研究了离子液体的分子结构与酸类型、酸强度的相关性。结果表明,乙腈探针法和吡啶探针法均能很好地区分离子液体的酸类型(Brnsted酸或Lewis酸),并可以粗略地指示离子液体的Lewis酸强度。更多还原

【Abstract】 The acidity of ionic liquid is determined by using acetonitrile and pyridine as a probe molecule.The correlation between the molecular structure and acidic type and acidity is studied.The results show that the type of acid(Brsted or Lewis acid) can be distinguished by using acetonitrile and pyridine as a probe molecule,and the acidity of Lewis acid of ionic liquid can also be determined roughly.更多还原
