The use of room temperature ionic liquids (RTILs) in chemical applications has gained significant and varied interest over the last few decades. In addition to use as novel reaction media they have enjoyed applications in materials, catalysis, and separations amongst others. RTILs possess a unique set of chemical and physical properties, some of which are tuneable, making them attractive targets for investigation. Such properties include tuneable liquid range, viscosity, volatility, polarity, and biodegradability. RTILs can also have high conductivity, thermal and electrochemical stability and superior solvating ability. However, there are a number of concerns related to RTILs that need to be addressed if they are to enjoy widespread use. These include attention being given to entire life cycle, manufacture and disposal of RTILs, toxicity, biodegradability, and cost. Specific applications of RTILs of interest to our research such as in metal separations and catalysis require that issues related to RTIL leaching, water miscibility, and metal binding ability be adequately addressed.
