Estimation of alcohol adsorption parameters at hydrocarbon/water interfaces in systems containing various hydrocarbons

摘要

The modified Kamlet-Taft model was used to correlate adsorption parameters (adsorption constants in Szyszkowski and Temkin equations, surface excess and molecular area at saturated interfaces and free energy, enthalpy and entropy of adsorption) of aliphatic alcohols at hydrocarbon/water interfaces with solvent parameters, temperature and molar intrinsic volume of alcohols. Statistically valid equations were obtained which can be used to predict the adsorption behavior of alcohols in extraction systems. (C) 1998 Elsevier Science B.V. [References: 24]
