ABSTRACT
The viscosity of the binary system 1-propanol + toluene has been measured with a falling-body viscometer for seven compositions as well as for the pure alcohol in the temperature range (293.15 to 353.15) K and up to 100 MPa with an experimental uncertainty of +- 2 %. At 0.1 MPa, the viscosity has been measured with a classical capillary viscometer (Ubbelohde) with an uncertainty of +- 1 %. A total of 216 experimental data points are reported. The viscosity behavior of this binary system is interpreted as the results of changes in the free volume and the breaking or weakening of hydrogen bonds. These data have been used to study the performance of two compositional models and a free-volume model.
