Extraction of 5-Hydroxymethylfurfural under Hydrogen Peroxide in Liquid–Liquid Slug Flow of Water / Methylisobutylketone Biphasic System and Effect of Hemin
Continuous extraction process of 5-hydroxymethylfurfural (HMF) in the liquid-liquid slug flow of water/methyl isobutyl ketone (MIBK) formed in the microcapillary was examined under hydroperoxide (H2O2) as a reactive oxygen species (ROS). Addition of H2O2 reduced the extracted amount of HMF into the MIBK phase. However, the addition of hemin recovered the HMF extraction. This probably resulted from the competitive binding of H2O2 and HMF to hemin. The binding of hemin to H2O2 and HMF contributed to anti-ROS activity and an accelerated mass-transfer of HMF, respectively.
