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...

Interaction between High-Voltage Cathode Materials and Ionic Liquids for Novel Li-Ion Batteries

The fast-growing market on electronic portable devices is possibly due to the development of Li-ion batteries. Besides, such batteries are the most promising candidates as energy storage media in (hybrid) electric vehicles, in the near future. However, improvements on electrochemical performances and on safety need to be achieved. With respect...

Reactions and Separations in Green Solvents

Most chemical processes involve solvents in the reaction and the separation step. These solvents give rise to a heavy environmental and economical burden. Moreover, these solvents are based on non-sustainable resources like petroleum. The aim of this thesis has been to develop a number of alternative processes based upon green (sustainable)...

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...

The ideal solution

A smart use of high-pressure carbon dioxide may make a special class of eco-friendly solvents known as ionic liquids much more attractive to the fine chemical industry. Researcher Dr. Maaike Kroon has demonstrated that, on paper at least, the savings can be astronomical.

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...
