Using an oxygen-bomb combustion calorimeter the molar combustion heats of the ionic liquids of alkylimidazolium chloride: 1-methyl-3-ethylimidazolium chloride (C2MIC), 1-methyl-3-butylimidazo- lium chloride (C4MIC), 1-methyl-3-pentylimidazolium chloride (C5MIC), and 1-methyl-3-hexylimidazolium chloride (C6MIC), were determined at (298.15±0.01) K. The standard molar combustion enthalpies and the standard molar formation enthalpies were calculated. With standard molar enthalpies of solution of C2MIC, C4MIC, C5MIC and C6MIC in literature, the standard molar enthalpies of formation of C2MI+, C4MI+, C5MI+, and C6MI+ were obtained. The contribution of one methylene group to the and was also estimated, respectively.

Key words: alkylimidazolium chloride, ionic liquid, oxygen-bomb combustion calorimetry, enthalpy of combustion, enthalpy of formation
