纯1-乙基-3-甲基咪唑四氟硼酸盐、1-甲基吡咯烷-2-一、吡咯烷-2-一、吡啶以及1-乙基-3-甲基咪唑四氟硼酸盐(1) + 1-甲基吡咯烷-2-一或吡咯烷-2-一(2)的三元混合物的密度、ρ、声速、u、热容、Cp + 吡啶 (3) 及其 1-甲基吡咯烷-2-酮或吡咯烷-2-酮 (2) + 吡啶 (3) 的二元混合物已在 (293.15、298.15、303.15 和 308.15) K 和大气压力下作为组成的函数进行测量。观察到的声音数据的密度和速度已用于确定所研究混合物的过量摩尔体积 VE 和过量等熵压缩率 κSE。观察到的二元和三元混合物的热力学性质已经通过利用混合物成分的拓扑（图论）进行了计算。据观察，图论成功地描述了所研究的二元和三元离子液体混合物的 VE 和 κSE 数据。
The densities, ρ, speed of sound, u, heat capacities, Cp of pure 1-ethyl-3-methylimidazolium tetrafluoroborate, 1-methyl pyrrolidin-2-one, pyrrolidin-2-one, pyridine and ternary mixtures of 1-ethyl-3-methylimidazolium tetrafluoroborate (1) + 1-methyl pyrrolidin-2-one or pyrrolidin-2-one (2) + pyridine (3) and their binary mixtures of 1-methyl pyrrolidin-2-one or pyrrolidin-2-one (2) + pyridine (3) have been measured as a function of composition at (293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. The observed densities and speeds of sound data have been employed to determine excess molar volumes, VE and excess isentropic compressibilities, κSE of the investigated mixtures. The observed thermodynamic properties of the binary as well as ternary mixtures have been calculated by utilizing the topology of the constituents of mixtures (graph theory). It has been observed that graph theory successfully describes well the VE and κSE data of the studied binary and ternary ionic liquid mixtures.
