Green Solvents for Green Technologies

In many industrial processes, large quantities of volatile and flammable organic solvents are used in various reaction systems and separation steps defining a major part of environmental and economic performance of a process. Accordingly, a growing area of research in the development of green technologies is devoted to designing new, environmentally-friendly and tuneable solvents which use would meet both technological and economical demands. Over the last few years, natural deep eutectic solvents (NADESs) have been dramatically expanding in popularity as promising alternatives to traditional organic solvents. NADESs may be considered as ‘designer solvents’ due to their numerous structural variations and possibility to design their physicochemical properties. Furthermore, NADESs are based on compounds that are safe for human consumption which opens numerous possibilities for their applications in the field of life sciences. One of the applications of NADESs is extraction of biologically active compounds from plant material. A few studies, in which NADESs have been applied for the extraction of bioactive compounds, showed that many compounds are dissolved better than in water or lipids. Herein, a brief overview of the up to date knowledge regarding these solvents, with special emphasis on extraction of phenolic compounds from grape pomace will be presented.
