Interfacial tensions of sixteen systems (pyridinium-based ionic liquid + n-alkane or n-alkanol) have been measured in the temperature range (283.15–313.15) K and at pressure of 0.1 MPa. The ionic liquids used were: 1-butylpyridinium tetrafluoroborate, 1-butyl-2-methylpyridinium tetrafluoroborate, 1-butyl-3-methylpyridinium tetrafluoroborate, and 1-butyl-4-methylpyridinium tetrafluoroborate. On the other hand, the organic solvents were: n-hexane, n-octane, n-hexanol, and n-octanol. The surface tensions of the organic liquids were also measured. The interfacial tensions for the systems involving n-alkanes are higher than for the systems containing n-alkanols. All the interfacial tensions decrease linearly with temperature. In addition the results have been interpreted using the equation proposed by Girifalco and Good.

16个系统的界面张力（基于吡啶鎓离子液体+  ñ烷烃或ñ链烷醇）已在温度范围（283.15-313.15）K，并在0.1MPa的压力被测量。所使用的离子液体为：四氟硼酸1-丁基吡啶鎓，四氟硼酸1-丁基-2-甲基吡啶鎓，四氟硼酸1-丁基-3-甲基吡啶鎓和四氟硼酸1-丁基-4-甲基吡啶鎓。在另一方面，所述有机溶剂为：Ñ己烷，Ñ辛烷，Ñ己醇，和Ñ辛醇。还测量了有机液体的表面张力。包含正构烷烃的系统的界面张力高于包含正构烷烃的系统的界面张力正链烷醇。所有的界面张力都随温度线性降低。另外，已经使用Girifalco和Good提出的方程式解释了结果。
