In the present work viscosity data for two dipentaerythritol esters (DiPEs) from (303.15 to 373.15) K up to 60 MPa are reported. The experimental measurements were performed with a rotational automated viscometer Anton Paar Stabinger SVM3000 at 0.1 MPa and a rolling-ball viscometer Ruska 1602-830 for high pressures. Modified Vogel-Fulcher-Tammann (VET) equations are used to represent the temperature and pressure dependence of the viscosity. The viscosity data have been superpositioned as function of the product of the temperature, T, and the volume, V, raised to an exponent gamma, namely, the scaling parameter, TV(gamma). comparison between the values of this characteristic scaling parameter for the DiPEs with those of other complex esters has been performed.
