since both the thermodynamics and k

since both the thermodynamics and kinetics of reactions carried out in ionic liquids are different to those in conventional molecular solvents. In general, ionic liquids consist of a salt where one or both the ions are large, and the cation has a low
degree of symmetry [127]. These factors tend to reduce the lattice energy of the crystalline form of the salt, and hence lower the melting point [128]. Ionic liquids come in two main categories, namely simple salts (made of a single anion and cation) and binary ionic liquids (salts where equilibrium is involved). Ionic liquids
have been described as designer solvents [129], and which means that their properties can be adjusted to suit the requirements of a particular process.
