| titleOfInvention | A kind of method that utilizes ionic liquid to catalyze fructose into 5-hydroxymethyl furfural |
| abstract | The invention belongs to the technical field of 5-Hydroxymethylfurfural preparation, and in particular relates to a method for converting fructose into 5-Hydroxymethylfurfural by utilizing ionic liquid catalysis; the steps are as follows: selecting hexamethylenetetraminesulfonic acid butyl hydrogen sulfate Or N,N disulfonic acid butyltriethylenediamine hydrogen sulfate is a catalyst, 1-butyl-3-methylimidazolium chloride or dimethyl sulfoxide is a solvent, mixed with fructose in proportion, and the mode of heating in a water bath is adopted The production of 5-hydroxymethyl furfural is extracted with ethyl acetate, and the catalyst and the solvent can be recovered and reused by vacuum drying; the catalytic system adopted in this method has little environmental pollution, is not easy to corrode equipment, has strong repeatability, and has high catalytic performance. With the characteristics of high activity and simple product separation, 5-hydroxymethyl furfural can be obtained quickly and efficiently, and the highest yield is 97.88%, which is a novel preparation method of 5-hydroxymethyl furfural. |
