Abstract
Density and viscosity measurements are performed for ethanol, water, hexamethyldisiloxane (MM), octamethyltrisiloxane (MDM), decamethyltetrasiloxane (MD2M) and their mixtures (ethanol/water, MM/MDM, MM/MD2M, MDM/MD2M) at 100 kPa at different temperatures (293 K – 423 K) and mixture compositions. To measure the density and viscosity, an IMETER measuring system with a combined dynamic and static force measurement method, a density meter with an oscillating U-tube measuring method and a Rheometer with a double-gap measuring system, were used. The experimentally determined data for the pure substances show a very good agreement with literature data. However, there is a strong deviation of the mixture viscosity between max. 7% for MM/MDM and 31% for MM/MD2M compared to Refprop v.10.0. In order to enable an improvement in the calculation of the density and viscosity for the mixtures, specific parameters for the Jouyban-Acree model are developed for all mixtures and thereby, a better description of the density and viscosity for the mixtures could be achieved.
