Measurement of density and viscosity of binary 1-alkanol systems (C-8-C-11) at 101 kPa and temperatures from (283.15 to 313.15) K
In this paper, we present the experimental values of the density and dynamic viscosity, obtained at 101 kPa, for binary systems containing 1-octanol, 1-nonanol, 1-decanol, and 1-undecanol over the entire range of mole fractions and at the following temperatures: (283.15, 288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K. The experimental viscosity data have been correlated by means of a model previously developed in our group. The binary interaction parameters of this model are also presented. The agreement between experimental and calculated values is quite good. The overall mean relative standard deviations are 0.2 % for the system 1-octanol + 1-nonanol, 0.5 % for the system 1-octanol + 1-decanol, 0.7 % for the system 1-octanol + 1-undecanol, 0.2 % for the system 1-nonanol+l-decanol, 0.6 % for the system 1-nonanol + 1-undecanol, and 0.2 % for the system 1-decanol + 1-undecanol.
