Abstract: In this paper, studies were conducted in order to improve the calculation accuracy of acid-base constants measured by inverse gas chromatography. The conventional a·(γ(d)(l))(0.5) parameters of DCM (dichloromethane), TCM (trichloromethane), and EtAcet (ethyl acetate) were corrected as 185, 212, and 235 Å(2)(mJ/m(2))(0.5) by analyzing the relationship between a·(γ(d)(l))(0.5) and the boiling temperature of the probe solvents, where a is molecular area and γ(l)(d) is surface dispersive free energy of the probe s…
