摘要

A new green technology was developed using citrus peel waste to produce hydroxymethylfurfual (HMF). FT-IR analysis of the waste showed 4 characteristic vibration modes (C-H, C-O, C-OH, and C=O/COO~-), contributing to sugars. XRD and FESEM elucidated that the waste and its hydrolysate consist of highly amorphous clusters. HC1 increased HMF yield by 1.4-fold. CrF3 increased its yield by 1.7-fold. At 0.2 of the stoichiometric ratio value, HMF yield was highest. The highest HMF yield was achieved in the reaction mixture of 4 g [0MIM]C1, 1 mL ethyl acetate, 0.1 g CrF3, 5 mL 0.3 M HC1, and 0.5 g biomass.
