The heterogeneous catalyst, silica-supported sodium hydrogen sulfate (NaHSO4 - SiO2) has been found to be highly efficient in carrying out the transformation of p-hydroxybenzyl alcohols at room temperature to p-hydroxybenzyl ethers and thioethers in very high yields.

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
