Synthesis of novel functional ionic liquids and their application in biomass

Abstract

A series of dicationic and monocationic ionic liquids (ILs) were synthesized and investigated and it was found that these functional ILs have important implications in the design of homogeneous and heterogeneous systems.

Synthesis of functional dicationic ionic liquids for the treatment of lignocellulosic biomass

“…A similar protocol was employed for the preparation of hexafluorophosphate [1-(1-pyridinium-yl-pentyl)-4-methylimidazolium] bromide ([PF 6 ][(PYR)C 5 (MIM)][Br]). 11 …”

“…Our previous study showed that the miscibility of DILs in water could be altered by the combination of a hydrophobic anion (PF 6 − ) and a hydrophilic anion (Cl − ). 11 However, in current studies, there is very limited information concerning the application of DILs. It is therefore necessary to investigate DILs for the treatment of lignocellulosic biomass.…”

Screening of highly efficient fungi for the degradation of lignocelluloses by ionic liquids-assisted cellulase

“…This is different with P. janthinellum FHH1 and P. oxalicum FLY4, because high hydrolysis efficiency was observed with ILs-pretreated corn stalk. [PF6] at 100 °C, a high reducing sugar yield for corn stalk was achieved at 18.80% (Han et al 2019). The residue was obtained at 68.75% after ILs treatment.…”

“…Ionic liquids were synthesized according to Han et al (2019). Pyridine (1.0 mmol) and 1,4-dichlorobutane (1.0 mmol) were reacted at 60 °C for 4 days.…”

“…) at 100 °C for 3 h, followed by the addition of 1.5 mL of deionized water for 3 h (Han et al 2019). The residue was filtered and washed with water.…”
