| 摘 要： | 烷基链的长短和对称性影响着四烷基季铵离子液体的理化性质,影响着其应用前景.本实验室设计、合成了系列新型丁基三乙基季铵型功能化离子液体,该类离子液体与之前报道的相应离子液体相比,具有相对较低的熔点,同时也具有更低的粘度.合成的离子液体中阴离子分别是三氟甲基磺酰根((CF3SO2)2N-)、六氟磷酸根(PF6-)、四氟硼酸根(BF4-)、硫酸氢根(HSO4-)、硫氰酸根(SCN-)和对甲苯磺酸根(PTSA-);利用核磁共振仪、密度仪、热分析仪、黏度仪、元素分析仪对其进行表征;研究了其与常规溶剂的相溶性,并对其结构和性质之间的关系进行探讨.

| Abstract: | The length of the alkyl groups and the symmetry of the cations in tetraalkylammonium-based ionic liquids affect the physical properties and their applications.A novel class of ionic liquids based on triethylbutylammonium cation was prepared in our group.In this series,(CF3SO2)2N-bis(trifluoromethanesufonyl)imide],PF6-,BF4-,HSO4-,SCN-and PTSA-(p-toluenesulfonic acid) were assigned to be the counter ions for the ionic liquids.The synthesis of ionic liquids started with the reaction of triethylamine and n-but... |
