Sustainable Ways of Combining Reactions and Separations Using Ionic Liquids and Carbon Dioxide

Traditional chemical processes show shortcomings caused by using volatile organic compounds as solvents during reactions and separations. Therefore, it is necessary to address this issue by moving toward more environmentally friendly processes. This is possible by using less toxic and hazardous solvents, such as ionic liquids and supercritical...

Phase Behaviour, Thermodynamics and Kinetics of Clathrate Hydrate Systems of Carbon Dioxide in Presence of Tetrahydrofuran and Electrolytes

In view of the possibilities for new development of carbon dioxide hydrate processes, this study focused on experimental measurements to obtain fundamental insight into the phase behaviour and the kinetic of formation of carbon dioxide hydrate forming systems. These data are essential for the development of process design of any carbon dioxide...

Fluid phase behaviour of ionic liquid-based systems of interest for green processes: Measurements and modelling

In the last decades a large number of applications with ionic liquids (IL) have emerged, and since the discovery that carbon dioxide can tune the miscibility of IL+organic mixtures, special attention has been drawn to the use of IL and CO2 as combined solvents for synthesis and extractions. To evaluate the applicability of the miscibility switch...

Combined reactions and separations using ionic liquids and carbon dioxide

A new and general type of process for the chemical industry is presented using ionic liquids and supercritical carbon dioxide as combined reaction and separation media. In this process, the carbon dioxide pressure controls the miscibility of reactants, products, catalyst and ionic liquid, enabling fast atom-efficient reactions in a homogenous...
