英文摘要	increasing the glucose loading in the 1-butyl-3-methylimidazolium chloride ([bmim]cl) ionic liquid containing a dissolved crcl3 catalyst system led to excessive formation of humins and a serious decrease in the 5-hydroxymethylfurfural (5-hmf) yield. a biphasic system containing glycol dimethyl ether (gde) as the extraction phase, and [bmim]cl/crcl3/glucose in combination with a partitioned amount of gde and an appropriate amount of water as the reaction phase was found to be highly efficient for the reaction; crcl3 catalyzed the formation of 5-hmf in 64.5 mol% yield from a very high glucose concentration (80 wt% with respect to the ionic liquid) at 108 degrees c. this 5-hmf yield in the [bmim]cl-gde-h2o ternary biphasic system nearly doubled that obtained in the single [bmim]cl/crcl3/glucose reaction phase. importantly, the gde phase contained about 56% of the generated 5-hmf without detectable contamination by the ionic liquid or carbohydrates. gde served multiple functions: as a hydrogen-bond acceptor, it exhibited excellent extraction performance for 5-hmf; due to its low boiling point and suitable solubility saturation point in the ionic liquid, a sustained gde bubbling phenomenon in the ionic liquid phase was observed that promoted the rate of inter-phase mass-transfer of 5-hmf in reactions; and gde mediated the [bmim]cl phase to a reduced viscosity. in addition, an appropriate amount of water in the ternary system promoted the extraction efficiency of 5-hmf and also lowered the viscosity of [bmim]cl/glucose. the ionic liquid-organics-water ternary biphasic system has been demonstrated for high 5-hmf productivity and separation efficiency.
