摘要：
Current analysis pertains with the measurement of molar heat capacities, (CP)123 for 1-butyl-2,3dimethylimidazolium tetrafluoroborate [Bdmim][BF4] or 1-ethyl-3-methylimidazolium tetrafluoroborate [Emim][BF4] (1) + 1-methylpyrrolidin-2-one (NMP) (2) + pyrrolidin-2-one (2-PY) (3) ternary and CP for [Bdmim][BF4] (1) + NMP (2) or 2-PY (3) binary mixtures within temperature series 293.15-308.15 K in a gap of 5 K. Excess heat capacities, (CEP)123, CEP have been determined using measured data. (CEP)123, CEP are positive at studied compositions for the ternary and binary mixtures, respectively. (CEP)123, CEP data have been tested in terms of Graph theory. A reasonable agreement has been perceived between experimental and calculated (CEP)123, CEP data.
