Abstract
The invention relates to a process for the production of a mixture of 5-hydroxymethylfurfural and glucose from a feedstock containing fructose in the presence of at least one polar aprotic solvent and of at least one dehydration catalyst, in which process the reaction temperature is less than 90° C.
Claims10
A process for 5-hydroxymethylfurfural, comprising bringing a feedstock of sucrose or a mixture of glucose and fructose into contact with methanesulfonic acid and/or HCl as catalyst in dimethyl sulfoxide as solvent, said process being carried out at a temperature of 50 to 90° C. and which process selectively converts fructoside units of the feedstock in contrast to the glucoside units of the feedstock, and in which the feedstock is introduced in an initial concentration by weight of fructoside units of greater than or equal to 7% by weight with respect to the total weight of the dimethyl sulfoxide.
