  • Design of Ionic Liquids for Electrochemical Applications
    作者:Masahiro Yoshizawa、Asako Narita、Hiroyuki Ohno
    DOI:10.1071/ch03240

    Zwitterionic liquids composed of a tethered cation and anion were synthesized and their thermal properties and ionic conductivity were investigated as novel ionic liquids especially for electrochemical applications. We prepared nine zwitterions in this study. In addition, this paper includes 36 kinds of zwitterions already reported in order to discuss the relationship between the zwitterion structure and their properties. Most zwitterions melt above 100°C; their melting points are generally higher than that of simple ionic liquids. When an equimolar amount of lithium salt (LiTFSI, LiBETI, LiCF3SO3, LiBF4, or LiClO4) was added to the zwitterion, the mixture showed only a glass transition temperature Tg. The Tg values of the zwitterionic liquid/salt mixture showed the lowest value of –37°C when mixed with LiTFSI. This mixture also showed the highest ionic conductivity of 8.9 × 10–4 S cm–1 at 100°C. There is a good relationship between Tg and the ionic conductivity of the zwitterionic liquid/lithium salt mixtures.

    我们合成了由系链阳离子和阴离子组成的齐聚物,并研究了它们作为新型离子液体(尤其是用于电化学应用的离子液体)的热特性和离子传导性。在这项研究中,我们制备了九种齐聚物。此外,本文还包括 36 种已报道过的齐聚物,以讨论齐聚物结构与其性质之间的关系。大多数齐聚物的熔点高于 100°C;它们的熔点通常高于简单离子液体的熔点。当等摩尔量的盐(LiTFSI、LiBETI、LiCF3SO3、LiBF4 或 LiClO4)加入到三元共轭物中时,混合物仅显示出玻璃化转变温度 Tg。当与 LiTFSI 混合时,齐聚物液体/盐混合物的 Tg 值最低,为 -37°C。这种混合物还显示出最高的离子电导率,在 100°C 时为 8.9 × 10-4 S cm-1。齐聚物液体/盐混合物的 Tg 与离子导电率之间存在良好的关系。

    日期:——
    Direct hydroxylation of p-xylene to 2,5-xylenol with hydroxylamine was carried out in an ionic liquids/molybdenum catalytic system. High 2,5-xylenol selectivity (80-98 %) can be achieved with good p-xylene conversion (5.9-9.9 %) in this catalytic system. The recycling experiments suggested the ionic liquids/molybdenum catalytic system was stable enough to be recycled for the hydroxylation reaction.
