Solid–liquid equilibria of three binary systems: {1-Ethyl-3-methylimidazolium hexafluorophosphate + 2-phenylimidazole, or 4,5-diphenylimidazole or 2,4,5-triphenylimidazole}

The phase diagrams of binary mixtures formed by 1-ethyl-3-methylimidazolium hexafluorophosphate ([emim][PF6]) and 2-phenylimidazole or 4,5-diphenylimidazole or 2,4,5-triphenylimidazole has been established using differential scanning calorimetry. Solutions containing 2,4,5-triphenylimidazole display phase splitting at high temperature range.
