The decomposition temperature of the protic ionic liquids (PILs) is directly proportional to the thermodynamic stability of their ion pairs. The decomposition temperature increases with decreasing difference in the anion and base proton affinity in the gas phase. The melting points of the PILs with the same anion decrease as the hydrocarbon radical in the alkylimidazolium cation becomes longer, which
质子离子液体 (PIL) 的分解温度与其离子对的热力学稳定性成正比。分解温度随着气相中阴离子和碱质子亲和力差异的减小而增加。具有相同阴离子的 PIL 的熔点随着烷基咪唑阳离子中的烃基变长而降低,这与较弱的离子-离子相互作用有关。
