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 arid were carried out by two different method's. One is based on a falling-body viscometer, whereas the other rests on a quartz crystal resrmator 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 iiiethod was used to describe the viscosity in terms of density and temperainre.
