We applied DSC for the determination of enthalpies of synthesis reactions of pyridinium- and pyrrolidinium-based ionic liquids (ILs) from pyridine (or N-methyl-pyrrolidine) and n-alkyl bromides (with n = 4, 5, 6, 7, and 8). The combination of reaction enthalpy measurements by DSC with modern high-level first-principles calculations opens valuable indirect thermochemical options to obtain values of enthalpies of the formation and vaporization enthalpies of ILs.
我们应用差示扫描量热法(DSC)来确定由吡啶(或N-甲基吡咯烷)和n-烷基溴化物(n=4, 5, 6, 7和8)合成的吡啶离子液体(ILs)和吡咯烷离子液体的合成反应焓。通过DSC测量反应焓与现代高水平第一原理计算的结合,为获得离子液体的形成焓和蒸发焓值提供了有价值的间接热化学选项。
