Synthesis of cyclic carbonates from CO2 and epoxides with

Ionic liquids have been a very popular alternative reaction media in recent decades because of their very low vapor pressure and non-flammability compared to conventional organic solvents Ionic liquids have also been widely used in chemical synthesis and catalysis A deep eutectic solvent (DES) is an ionic solvent which is easily prepared air/moisture insensitive and frequently

Deep Eutectic Solvent Assisted Facile Synthesis of Lignin

In this study we reported a method to prepare a lignin based cryogel by cross-linking deep eutectic solvent (DES) extracted lignin and formaldehyde as an alternative to replace resorcinol-formaldehyde (RF) based aerogel The resulting lignin-formaldehyde cryogel has a highly porous structure (172 8

Therapeutic deep eutectic solvents as solubility enhancers

In recent years deep eutectic solvents (DES) have emerged as a sustainable alternative to ionic liquids mainly due to their lower production costs and higher biodegradability/ biocompatibility(1) DES are defined as a mixture of organic compounds with a melting point significantly lower than that of either individual component(2) When based in natural compounds such as aminoacids organic

Preparation of magnesium cobalt and nickel ferrite

Natural deep eutectic solvents (DESs) dissolve simple metal oxides and are used as a reaction medium to synthesize spinel-type ferrite nanoparticles MFe2O4 (M=Mg Zn Co Ni) The best results for phase-pure spinel ferrites are obtained with the DES consisting of choline chloride (ChCl) and maleic acid By employing DESs the reactions proceed at much lower temperatures than usual for the
