| dc.description.abstract | Density of the ionic liquid [C6mim][NTf2] – a reference ionic liquid for thermophysical properties, as proposed by IUPAC8 was measured using an Anton Paar density meter DMA HP. The basic experimental setup was described previously, and the modifications introduced in order to avoid water contamination of the sample are described in the presentation. The measurements were performed in the temperature range (283.15 ≤ T ≤ 353.15) K and at pressures (0.1 ≤ p ≤ 65) MPa. The water content of the samples was measured by Karl-Fisher coulometry, both before and after the measurements. As the viscosity of that ionic liquid is much higher than the viscosity of the fluids used in the calibration of the densimeter, a correction of the results became necessary, to account for the consequent error in the period of oscillation of the U-tube. For this purpose, the viscosity effect on the density measurements on the Anton Paar DMA HP was quantified using the viscosity standard specimen (200GW) from ZMK, GmbH. The experimental determination of the viscosity correction to the measured density is described and also the preliminary results of the density of [C6mim][NTf2] are compared with literature values. | por |
