Ionic Green Solvents from Renewable Resources

Abstract

Nature provides a vast new vista of opportunities for the preparation of new recyclable solvents. Natural compounds have been recently used to prepare the cationic or anionic moiety of room‐temperature ionic liquids. In many cases, these new solvents, based on modifications of natural products, contain chiral centres and/or specific functional groups. This paper is an overview in an area of research that is destined for rapid development and expansion. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

Thermophysical Properties of Ionic Liquid, 1-Pentyl-3-methylimidazolium Chloride in Water at Different Temperatures

“…In these equations, β (0) , β (1) , and C φ are the ion interaction parameters of the Pitzer model that are dependent on temperature and pressure and A φ is the Debye-Hückel constant for the osmotic coefficient on the molal scale. A φ values for water are given in Table 2 at temperatures T = (298.15 to 328.15) K [48].…”

“…dissolution ability for organic, inorganic, and polymeric compounds, ease of recycling, and nonflammability [1][2][3]. Therefore, they can replace toxic, flammable traditional volatile organic solvents in many research and industrial applications [4][5][6][7].…”

Mizoroki–Heck Reactions: Modern Solvent Systems and Reaction Techniques

“…The use of ionic liquids in Mizoroki-Heck reactions has been described in several reviews [9,12,[24][25][26]. Modern trends of Mizoroki-Heck reactions in ionic liquids are the application of new ligand types, like N-heterocyclic carbene (NHC) ligands, supported catalysts, combination with ultrasound irradiation, microwave irradiation and multiphase catalysis.…”

Chiral ionic liquids: A compendium of syntheses and applications (2005–2012)

“…Therefore, like amino acid derived CILs, sugar derived CILs are also thought to be more environmentally sustainable and relatively inexpensive to synthesize from biorenewable raw materials, compared with traditional ILs, which contain synthetic chemicals derived from petroleum. 68 However, surprisingly, this area is not as thoroughly explored as other areas of CIL synthesis and has a rather brief history. A very comprehensive review including the history and advancements of sugarderived ionic liquids was published in 2011 by Marra et al, 69 and readers are directed to it for more details.…”
