Abstract

We investigated the extraction of 5-hydroxymethylfurfural (5-HMF) from 1-ethyl-3-methylimizadolium chloride ([C2mim]Cl), which is produced by heating of sugar in the ionic liquid, [C2mim]Cl. It is found that 5-HMF can be obtained from sucrose at 28.8wt% of the yield by heating at 140 ºC for 10 min under microwave irradiation. For evaluating the extraction of 5-HMF from [C2mim]Cl, we determined “the degree of extraction”, which is defined as percentage of extracted 5-HMF from [C2mim]Cl, and “selectivity”, which is defined as percentage of 5-HMF in all extracted substances from [C2mim]Cl. Effective extraction at 67.3% of the degree of extraction and 99.4% of selectivity can be attained by using the mixture of hexane and acetone after adding water to [C2mim]Cl.
