Infinite-dilution activity coefficients of n-alcohols (C-1-C-8) in water were measured by using the relative gas-liquid chromatographic method proposed by Orbey and Sandler [1991]. The temperature range of measurement was 298 to 343 K. The gamma(infinity) values at 298.15 K varied from 1.72 (methanol) to 1970 (n-heptanol). ASOG, UNIFAC, modified UNIFAC (Dortmund). modified UNIFAC (Lyngby) group contribution methods could predict gamma(infinity) to within 16.9, 28.8, 23.9 and 31.8 average percent error, respectively, for all systems and temperatures.
