Densities and Viscosities of the Binary Mixtures of Tetrahydrofuran with Isomeric Chlorobutanes at 298.15 K and 313.15 K

Abstract

Densities and kinematic viscosities of the binary mixtures tetrahydrofuran + isomeric chlorobutanes have been measured at atmospheric pressure at the temperatures of 298.15 K and 313.15 K. Excess molar volumes, dynamic viscosities, and viscosity deviations have been obtained from experimental data and fitted by the Redlich−Kister equation. Kinematic viscosities have been correlated using the McAllister equation. Excess molar volumes are negative in the whole composition range, while viscosity deviations are small in absolute value and present an inversion of sign for two systems only at one temperature.
