Activity Coefficients at Infinite Dilution of Organic Compounds in Acetonitrile and Methanol by Liquid Chromatography

Activity coefficients at infinite dilution of series of n-alkanes, n-alcohols, n-alkylbenzenes, cresols, α- and β-toluidine and γ -picoline in acetonitrile and methanol were determined at 25 °C by liquid-liquid chromatography. Apiezon L and Porapak Q were used as the stationary phases. For those components for which activity coefficients were available in the literature, there is reasonably good agreement with the data reported in this work, though in some cases the literature data were obtained by other techniques.
