ABSTRACT

The paper reports high pressure data of the viscosity of methyl caprate (C11H22O2) and ethyl caprate (C12H24O2). The measurements cover the temperature range from (293.15 to 353.15) K, from atmospheric pressure up to 200 MPa and were carried out by two different methods. One is based on a falling-body viscometer, whereas the other rests on a quartz crystal resonator technique. Based on the two sets of data, high pressure viscosity correlations are proposed to correlate within the experimental uncertainty the viscosity values as a function of temperature and pressure. Finally, a thermodynamic scaling method was used to describe the viscosity in terms of density and temperature.
