Density and surface tension of binary mixture of 1-nonanol +n-octane, +n-nonane, and +n-decane from (293.15 to 323.15) K at P = 0.1 MPa

Abstract

We present the density and surface tension of binary mixtures n-octane, n-nonane and n-decane with 1-nonanol in the entire composition range at atmospheric pressure. The surface tension is measured from 293.15 K to 313.15 K while the density is measured from 293.15 to 323.15 K. Densities are obtained from a vibrating tube densimeter and surface tensions are from a drop volume tensiometer. Excess molar volumes and surface tension deviations are calculated from the experimental measurements and they are represented using Redlich-Kister type equations. Surface entropy and enthalpy are calculated using the temperature dependence of the surface tension.
