Density and Surface Tension of Binary Mixtures of 2,2,4-Trimethylpentane + n-Heptane, 2,2,4-Trimethylpentane + n-Octane, Ethyl Acetate + Benzene, and Butanenitrile + Benzene from (293.15 to 323.15) K

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.
