A mixture of betaine formic acid was employed to convert n-glucose and n-fructose into 5-hydroxymethylfurfural (5-HMF) with high selectivity and also for the direct conversion of water-soluble starch and microcrystalline insoluble cellulose. The reactions were performed in average of temperature found between 160 and 200 degrees C regarding the nature of the substrate. The reactions were carried out under microwave heating and performed in a water-MIBK biphasic system at different ratios. In each case, the specific optimized condition gave values of HMF yields of 82%, 55%, 54% and 47% respectively from n-fructose, n-glucose, water-soluble starch and cellulose microcrystalline powder.
