Synthesis and characterization of a novel Gemini imidazolium ionic liquid-based deepeutectic solvents

A highly intended branch of green solvents, during recent decades, is the deep eutectic solvents (DES), whichhave become prevalent in industry. This study was devoted to introduce a DES based on the Gemini imidazolium[C۴im-C۶-imC۴][Br۲] IL and urea. A molar ratio of ۳:۲ for respectively, the Gemini-IL and urea was determinedfrom the phase diagram with a melting point of only ۱۴ °C, much less than that of forming constituents (۱۵۶ and۱۳۳ °C). The preparation of DES was notably energy-efficient and could be accomplished through simple mixingand heating of the components, bypassing the need for purification. The structure of the novel DES wasproposed and underwent validation through FT-IR analysis, revealing consistent structures
