Abstract

The present invention relates to the preparation method of 5-alkoxymethylfurfural where for preparation of the 5-alkoxymethyfurfurali is mixed at 10 to 90 0C 5-chloromethylfurfural (CMF) or 5-bromomethylfurfural (BMF), alcohol, and oil shale ash, redundant alcohol is removed from said mixture by evaporation and water is added to the viscous residue, thereafter the mixture is extracted with an organic solvent. If necessary, the solvent is dried and removed from product. According to the method of the invention the yield is more than 60%, while said furfurals contain less than 2% of esters of levulinic acid or of 2-(dialkoxymethyl)-5-(alkoxymethyl)furan.
