Abstract

Abstract : A ternary green solvent γ‐valerolactone (GVL)/choline chloride (ChCl)/H2 O system is used to convert rice waste to hydroxymethylfurfural (HMF) using AlCl3 ·6H2 O as a catalyst. The effect of the reaction time, temperature, substrate, catalyst, and catalyst amount on the extraction of HMF by GVL is studied under this system. The results show that in ChCl/H2 O, GVL/H2 O, and GVL/ChCl/H2 O systems, the HMF yield reaches the highest levels of 8.21, 12.24, and 18.60 mol% after reaction at 140 °C for 1 h, respectively. The yield of HMF obtained by reacting 0.42 mm of AlCl3 ·6H2 O at 140 °C for 30 min is significantly higher than that of CrCl3 ·6H2 O and FeCl3 ·6H2 O. After reaction at 140 °C for 5 min, the extraction rate of HMF by GVL reaches more than 80%. The aqueous solution of ChCl forming the ternary system has high recyclability, and after six times, the yield loss of HMF is small.

The effect of the reaction time, temperature, substrate, catalyst, and catalyst amount on the extraction of HMF by GVL is studied under this system. This system may be a new and green method of HMF production.
