Study of the effects of pressure on the viscosity and density of diisodecyl phthalate

In the present work viscosity data for three different samples with two different purity grades of diisodecyl phthalate (DIDP) are reported from 303.15 K to 373.15 K up to 60 MPa, together with density values from 283.15 K to 398.15 K and up to 70 MPa. The experimental measurements have been perform...

Description
Summary:In the present work viscosity data for three different samples with two different purity grades of diisodecyl phthalate (DIDP) are reported from 303.15 K to 373.15 K up to 60 MPa, together with density values from 283.15 K to 398.15 K and up to 70 MPa. The experimental measurements have been performed with a rotational automated viscometer Anton Paar Stabinger SVM3000, a rolling-ball viscometer Ruska 1602-830 for high pressures and a recently automated Anton Paar DMA HPM vibrating-tube densimeter. The measured data for viscosity have been compared with previous literature values and could be useful to establish together with previous viscosity data, a correlation of the full viscosity surface η( T, P) of DIDP. This correlation is needed for the calibration and verification of high-pressure viscometers at moderate viscosities.
