Abstract
NEWS & VIEWS the salt 1-methylimidazolium chloride, [Hmim]Cl, MATERIAL WITNESS which melts above 75 °C (Fig. 2a). Above this temperature, this salt is a colourless, dense, ionic liquid, immiscible with the reaction mixture, and which Patent pending separates as a discrete layer (Fig. 2b). This layer is then removed by gravity separation (much easier and atents, it is widely believed, cheaper than filtration), and the 1-methylimidazole exist to protect the individual is regenerated...
