reaction proceeds through the sequential transferhydrogenation and etherification of HMF to 2,5‐bis(alkoxymethyl)furan, a potentialbiodiesel additive, catalyzed by a Lewisacidzeolite, such as Sn‐Beta or Zr‐Beta. An alcohol is used as a hydrogen donor and as a reactant in etherification. This cascade reaction can selectively produce high yields of the biodiesel additive (>80 % yield) from HMF with the

Solving problems: An isopropyl alcohol‐mediated reaction system for the production of 5‐hydroxymethylfurfural (HMF) fromfructose reaches a yield of up to 87 %. The solvent can be easily recycled by evaporation, giving the HMF product. The system avoids the use of large amounts of organic solvent, has a minimal environmental impact, and offers a new route to large‐scale economically viable processes

Disclosed herein is a process for preparing 5-hydroxymethylfurfural comprising the step of contacting a carbohydrate and a Brønsted acid in an alcoholic solvent comprising an alcohol selected from the group consisting of secondary alcohols, tertiary alcohols, aryl alcohols and combinations thereof under conditions to dehydrate the carbohydrate thereby forming a reaction product containing 5-hydroxymethylfurfural.
