Abstract: Ionic liquids are organic inorganic multi component materials whose chemical (polarity / acidity / co-ordination ability / solubility) and physical (fluidity / conductivity / transferability / liquidus range) properties can be tailored by modifying /changing the type of cations, modifying the alkyl substance in the cations, or modifying / changing the type and the composition of the anions. Ionic liquids have attracted extensive interest in recent years as environmentally benign solvent due to their favorable properties, such as
nonflammability, negligible vapor pressure, reusability, high thermal stability and chemical stability. Over the past few years, a variety of catalytic reactions have been successfully conducted using ionic liquids as solvents as well as catalyst. Many interesting results have been obtained, which have demonstrated the advantages of using
ILs as the alternatives for organic solvents. Recent development of ionic liquids such as imidazolium based ionic liquids lead the investigations systematically in physical chemistry and in environmental studies as green catalysis. Nowadays both nanopoarticles
and ionic liquids have become the source of great achievements for the materials chemistry as a heterogeneous organocatalyst. Since the homogeneous reaction systems require a large amount of ionic liquids which is undesirable in the view points of economic and environment.
