Revisiting greenness of ionic liquids and deep eutectic solvents

Green Chemical Engineering, 2021
Green solvents are one of the hot topics of green chemistry. Ionic liquids (ILs) and deep eutectic solvents (DESs) are deemed as green solvents to a certain extent, and they have been applied in many areas, such as dissolution, separation, catalysis ...

Electrospun nanosized cellulose fibers using ionic liquids at room temperature [PDF]

, 2011
Aiming at replacing the noxious solvents commonly employed, ionic-liquid-based solvents have been recently explored as novel non-volatile and non-flammable media for the electrospinning of polymers.

Applied Biotransformations in Green Solvents

Chemistry – A European Journal, 2010
AbstractThe definite interest in implementing sustainable industrial technologies has impelled the use of biocatalysts (enzymes or cells), leading to high chemo‐, regio‐ and stereoselectivities under mild conditions. As usual substrates are not soluble in water, the employ of organic solvents is mandatory. We will focus on different attempts to combine

Altering the Coordination of Iron Porphyrins by Ionic Liquid Nanodomains in Mixed Solvent Systems [PDF]

, 2017
The solvent environment around iron porphyrin complexes was examined using mixed molecular/RTIL (room temperature ionic liquid) solutions. The formation of nanodomains in these solutions provides different solvation environments for substrates that could

Greener solvents for solid-phase synthesis [PDF]

, 2017
The use of a variety of green solvents to swell a diverse range of resins used in solid-phase synthesis is investigated. Good swelling is shown to depend on the structure of the resin and the solvent.

Polythiophenes and oligothiophenes in zeolite hosts [PDF]

, 1993
The polymerization of different thiophenes in the channels of molecular sieve zeolite hosts is described. Thiophene, 3-methyIthiophene, 2,2'-bithiophene, and terthiophene were introduced into dehydrated proton-, Cu(II)- or Fe(III)-containing zeolites ...
