Solvent Control of Electron Transfer Dynamics [PDF]

, 2003
We investigate the charge-transfer-to-solvent (CTTS) dynamics of sodide in several solvents. Since this CTTS system has only electronic degrees of freedom, the dynamics provide a window into how solvent motions control electron ...

Investigation on Conversion Pathways in Degradative Solvent Extraction of Rice Straw by Using Liquid Membrane-FTIR Spectroscopy

Energies, 2019
Degradative solvent extraction (DSE) is effective in both dewatering and upgrading biomass wastes through the selective removal of oxygen functional groups. However, this conversion mechanism has yet to be elucidated.

Conversion of Glucose to 5-Hydroxymethylfurfural, Levulinic Acid, and Formic Acid in 1,3-Dibutyl-2-(2-butoxyphenyl)-4,5-diphenylimidazolium Iodide-Based Ionic Liquid

Applied Sciences, 2021
The separation process between 5-hydroxymethylfurfural (HMF) and trace glucose in glucose conversion is important in the biphasic system (aqueous–organic phase), due to the partial solubility property of HMF in water.
