“…However, a P , increases with increasing temperature at low pressures, but it exhibits the opposite trend at high pressures. A similar behavior has been observed for some liquids, e.g., long-chain alkanes [29], dialkyl adipates [24], and an ionic liquid [30].…”

“…The possible use of ionic liquids as heat transfer fluids, for heat exchange in chemical plants and solar thermal power generation, from cryogenic temperatures up to 200 ºC, is based on the values of heat capacity per unit volume, very low vapor pressures, wide liquid ranges, thermal stability (some can be used at temperatures up to 500 ºC) has been discussed (Holbrey et al, 2003), and its comparison with the properties of synthetic compounds (based on hydrocarbons, polyaromatics and siloxanes), showed that common imidazolinium systems have higher heat capacities per unit volume than two high performance commercial thermal fluids, Paratherm HE ® and Dowtherm MX™, in all the applicable temperature range. This analysis was complemented (França et al, 2009;Nieto de Castro, 2010a) (França et al, 2009). These results are highly promising if we use these biodegradable and green ionic liquids in ionanofluids for their numerous potential applications.…”

The vibrating-wire viscometer has proven to be an exceedingly effective means of determining the viscosity of liquids over a wide range of temperature and pressure. The instrument has a long history but a variety of technological and theoretical developments over a number of years have improved its precision and most recently have enabled absolute measurements of high accuracy. However, the nature of the electrical measurements required for the technique has inhibited its widespread use for electrically conducting liquids so that there have been only a limited number of measurements. In the particular context of ionic liquids, which have themselves attracted considerable attention, this is unfortunate because it has meant that one primary measurement technique has seldom been employed for studies of their viscosity. In the last 2 years systematic efforts have been made to explore the applicability of the vibrating-wire technique by examining a number of liquids of increasing electrical conductivity. These extensions have been successful. However, in the process we have had cause to review previous studies of the viscosity and density of the same liquids at moderate temperatures and pressures and significant evidence has been accumulated to cause concern about the application of a range of viscometric techniques to these particular fluids. Because the situation is reminiscent of that encountered for a new set of environmentally friendly refrigerants at the end of the last decade, in this paper the experimental methods employed with these liquids have been reviewed which leads to recommendations for the handling of these materials that may have
