Abstract:
Due to the low toxicity, high conductivity and a significant electrochemical stability, ionic liquids can be used as green solvents and as a replacement for volatile organic solvents in many industrial processes. They are often called designed solvents. It is possible to synthesize ionic liquid with required properties in order to obtain the most suitable solvent. In this work, several ionic liquids with different inorganic anions such as nitrate, bromide and tetrafluoroborate were synthesized. Density, viscosity, electrical conductivity and thermal stability were also measured. Some ionic liquids were tested as solvents and media for different chemical reactions.
Although the green attributes of ionic liquids have helped scientist to develop many green and technologically safer processes, their impact on the environment is still under discussion. For new chemicals, such as ionic liquids, it is very important to evaluate their environmental impact, degradation and stability. Thus, the efficiency of different advanced oxidation processes for the removal of ionic liquid was studied. An attempt was also made to identify the reaction intermediates formed during the photo-oxidation process, using the LC-ESI-MS/MS and 1H NMR techniques.
