Simple, soluble sugars such as fructose can be converted completely to the platform chemicals such as 5-hydroxymethyl-2-furfural (HMF) under a wide range of conditions with solvent assisted aqueous acid cyclodehydrations.  Certain solvents can be induced to phase separate from the aqueous acid media allowing complete separation for recycle. The organic solvent is evaporated and recycled. Pure HMF results  in ~ 95% yield. The recycled acid and recovered solvent along with more sugar are reacted again to afford about the same yield and demonstrates actual recycle of reagent and solvent.
