Figure 2

Reaction conditions: 10 wt% glucose in water (0.55 mmol), n (AlCl3) = 0.025 mmol, pH = 2.50. (a) NaCl/aqueous phase mass ratio of 0.4, reaction temperature of 175 °C, reaction time of 20 min. (b) NaCl/aqueous phase mass ratio of 0.4, CPME to water volume ratio of 3.0, reaction time of 20 min. (c) NaCl/aqueous phase mass ratio of 0.4, CPME to water volume ratio of 3.0, reaction temperature of 175 °C. (d) CPME to water volume ratio of 3.0, reaction temperature of 175 °C, reaction time of 20 min.
