Transesterification were carried out under microwave irradiation conditions and the effects of imidazolium hydroxide with different branched alkyl side-chains ([Cnmim]OH, n = 2, 3, 4) were investigated. The results showed that less than conventional amount of NaOH, and the alkaline ionic liquids formed clearly biphasic systems immediately after the transesterification of soybean oil with methanol was finished. The method offers significant improvement over conventional techniques in terms of operational simplicity, processing time reduction and excellent yields. Among the imidazolium salts studied, [C2mim]OH proved to be the most efficient catalyst, affording 96 % yield.

In this work, the performance of selected ionic liquid-water mixtures was investigated for an acetone cooling application in a process plant using a double pipe heat exchanger. Cooling media such as river water and ionic liquid-water mixtures were compared, specifically water-saturated quaternary phosphonium-based carboxylate ionic liquids were considered in this work. Ionic liquids generally have high thermal stability, resist degradation, and provide higher temperatures at low vapor pressures and for these reasons, ionic liquids can be a good substitute for conventional heat transfer fluids. At each condition, the performance of the ionic liquid mixture was compared with that of water. For the designated cooling application, the performance of water was much better than the ionic liquid mixtures.
