摘      要：This study was to investigate the optimal additions of the cellulose decomposition reaction to obtain the most yield of 5-HMF and other furan derivatives in various biphasic systems with FeCl_(3)-CuCl_(2) mixed catalysts,and explore its depolymerization kinetics.A series of controllable reactions have been performed under mild environmentally friendly *** experiment results showed that49.13 wt%of 5-HMF was the maximum production along with 2.98 wt%other furan derivatives catalyzed by mixed Lewis acid FeCl_(3)-CuCl_(2) under the two phases which included high concentration NaCl aqueous phase and n-butanol organic phase at 190℃for 45 *** conclusion suggested that two-phase systems benefited the yield of 5-HMF,furan derivatives via extracting the target products from reaction phase to organic phase to avoid rehydration of *** kinetic calculation revealed the conversion with mixed catalysts had lower reaction apparent activation energy(21.65 kJ/mol,190-230℃)and the reaction rate was faster than that with acid-based *** on experiment exploration,the probable mechanism of cellulose decomposition with FeCl_(3)-CuCl_(2) was proposed.
