ABSTRACT

Surface tensions of the ternary mixtures containing an isomer of butanol (1-butanol, 2-butanol, 2-methyl-1-propanol, or 2-methyl-2-propanol) + n-hexane + 1-chlorobutane have been measured at atmospheric pressure and 298.15 K. From these experimental data, surface tension deviations were calculated and fitted by the Cibulka s equation. Experimental results have been compared to the predictions obtained by a group contribution method; furthermore, using this method, the excess surface molar compositions of n-hexane in the ternary mixtures have been also estimated.
