ABSTRACT

We measure the density and surface tension of four binary mixtures of 2,2,4-trimethylpentane + n-heptane and n-octane, and butanenitrile and ethyl acetate + benzene, from (293.15 to 323.15) K at atmospheric pressure. Densities are measured using a vibrating tube densimeter while surface tension is measured with a drop volume tensiometer. Excess molar volumes and surface tension deviations are calculated from the experimental measurements. Results are correlated with Redlich Kister type equations.
