value‐added ethers from bioderived aldehydes. Etherification of 5‐(hydroxymethyl)furfural with different aliphatic alcohols over acidic Zr–montmorillonite (Zr‐Mont) catalyst produced a mixture of 5‐(alkoxymethyl)furfural and 2‐(dialkoxymethyl)‐5‐(alkoxymethyl)furan. The latter was selectively converted back into 5‐(alkoxymethyl)furfural by treating it with water over the same catalyst. The synthesis of 2

Zr/Simixedoxides with different amounts of silica (0–50 wt%) were prepared by a simple sol–gel method. These catalysts were tested in a cascade reaction of furfural and 5-hydroxymethyl furfural (HMF) with 2-butanol to form the corresponding alcohols or ethers through a combination of transfer hydrogenation and etherification processes under mild conditions. The selectivity can be finely tuned by

The invention relates to a method for producing tetrahydrofurfuryl ethers, characterised in that it involves carrying out consecutive etherification/reduction reactions based on a compound containing at least one furan ring, in the presence of at least one alcohol and at least one catalyst, optionally in the presence of H
