Abstract

The special NMR monitoring technique showed that conversion of glucose and fructose to 5-hydroxymethylfurfural in ionic liquids is highly selective and the formation of by-products, mainly oligomers, is related to further dehydration of 5-hydroxymethylfurfural. The replacement of usual heating by microwave irradiation provides high conversion of glucose (93%) and good yield of 5-hydroxymethylfurfural (85%) at 80 °C within 2.5 min.

Dedicated to the Academician of the Russian Academy of Sciences I. P. Beletskaya on the occasion of her anniversary.
