Sažetak
For the separation of a homogenious mixture a second immiscible phase must be created or added in order to enhance mass transfer between two phases. Phase is created by an energy separating agent, ESA, and this process involves heat transfer. Processe that involves the addition of mass separating agent, MSA, are more complex since MSA must be recovered. Furthermore, if the feed and MSA are not completely immiscible the product will be contaminated with the MSA. Liquid-liquid extraction using selective solvent is widely used when distillation is not feasible for separation of liquid mixture. As for any other process that involves MSA, special care must be taken when selecting a proper solvent. Solvents commonly used in industry are volatile organic compounds that exhibit high vapour pressure. Additionally, volatile organic solvents are flammable and are of varying toxicity, depending on their nature. During past decade, an increasing trend of investigations concerning the possibilities of replacing the existing commercial solvents with ecologically acceptable, so called green solvents. Ionic liquids and their greener analogues deep eutectic solvents have attracted great attention because of their unique adjustable physical and chemical properties. The key advantages of these green solvents in this separation process are their high selectivity, non-volatility and their capability to dissolve different types of organic, inorganic and polymeric compounds. In addition, ionic liquids and deep eutectic solvents can easily be regenerated and even reused several times. In this review the major contributions of ionic liquids and deep eutectic solvents will be reported.
