Over recent years ionic liquids have gained in importance, causing a growing number of scientists and engineers to investigate possible applications for these liquids because of their unique physical and chemical properties. Their outstanding advantages such as nonflammable liquid within a broad liquid range, high thermal, mechanical, and chemical stabilities, low solubility for gases, attractive tribological properties (lubrication), and very low compressibility, and so forth, make them more interesting for applications in mechanical engineering, offering great potential for new innovative processes, and also as a novel hydraulic fluid. This paper focuses on the outstanding compressibility properties of ionic liquid EMIM-EtSO4, a very important physical chemically property when IL is used as a hydraulic fluid. This very low compressibility (respectively, very high Bulk modulus), compared to the classical hydraulic mineral oils or the non-flammable HFDU type of hydraulic fluids, opens up new possibilities regarding its usage within hydraulic systems with increased dynamics, respectively, systems' dynamic responses. © 2014 Milan Kambic et al.

Vaporization enthalpy of an ionic liquid (IL) is a key physical property for applications of ILs as thermofluids and also is useful in developing liquid state theories and validating intermolecular potential functions used in molecular modeling of these liquids. Compilation of the data for a homologous series of 1-alkyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)imide ([Cnmim][NTf2]) ILs has revealed an embarrassing disarray of literature results. New experimental data, based on the concurring results from quartz crystal microbalance, thermogravimetric analyses, and molecular dynamics simulation have revealed a clear linear dependence of IL vaporization enthalpies on the chain length of the alkyl group on the cation. Ambiguity of the procedure for extrapolation of vaporization enthalpies to the reference temperature 298 K was found to be a major source of the discrepancies among previous data sets. Two simple methods for temperature adjustment of vaporization enthalpies have been suggested. Resulting vaporization enthalpies obey group additivity, although the values of the additivity parameters for ILs are different from those for molecular compounds. © 2013 American Chemical Society.

In order to decrease the carbon dioxide (CO 2) content of gas streams to reach environmental or sales gas requirements, a series of different techniques have been established over the years. For example, in natural gas processing, aqueous amine solutions are commonly used as a washing media. A category of new fluids, ionic liquids (ILs), shows certain advantages compared to standard technologies, like non-volatile character and the absence of aqueous solutions. A great amount of research into CO 2 solubility in ILs in general has been performed over the last years, fewer in high pressure solubility. Nearly none have reached a state beyond laboratory scale. This paper presents the final experiments from a feasibility study, namely high pressure absorption of CO 2 from an inert component and the respective desorption by using columns at technical scale. The used IL is non-toxic, stable to hydrolysis and can practicably and reasonably be produced industrially with a novel high quality synthesis route. Measuring the pressure equilibrium data at different temperatures and generation of the corresponding diagrams was the basis for the column experiments. A fundamental point was to identify which phase flows disperse together with the consequent impact on the process. The investigation of the recycling behavior, as a sequence of absorption and desorption cycles, was a very important part of the project. Hence, it was possible to improve the balance point and the load line. The results promise the application of the novel process on an industrial scale soon. © 2012 Elsevier B.V.

Within the last decade the Carbonate Based Ionic liquid Synthesis (CBILS) has developed towards a widely applicable, greener and halogen free process for the industrial production of ionic liquids. A large number of diverse starting materials have been screened experimentally, to explore the structural limits of the core reaction step, which is the quaternization of nitrogen, phosphor or sulfur based nucleophiles with carbonic acid dialkyl or diaryl esters to the corresponding quaternary alkyl- or arylcarbonates. In order to overcome the large experimental effort of empirical screening, a practical method based on quantum-chemical calculation has been developed for an assessment of feasibility of chemical reactions. This method has been successfully tested with 16 typical CBILS reactions by calculation of their thermodynamic functions. Thermodynamic equilibrium constants as a measure for the practical yield of the CBILS reactions at 298 K and 393 K have been determined for both the gaseous state and the liquid state. The method has been evaluated by comparison of the theoretical results with experimental data and it can be considered as the powerful tool to reduce trial and failure for the industrial application of the CBILS process.
