METHOD FOR PREPARING 5-HYDROXYMETHYL-2-FURFURAL USING ACID CATALYST UNDER BIOMASS-DERIVED ETHYLENE GLYCOL-BASED SOLVENT

摘要

Use the ethylene glycol solvent under situation of methyl 5-hydroxy acid catalyst-2 -- the method for furfural is provided. Ethylene glycol-base compound of the manufacturing method of 5 methylol -2- furfurals in the present invention is linear or the period (ethylene glycol based compound), and being used as a solvent and 5-- from the fructose under acid catalyst (acid catalyst), it can prepare methylol -2- furfurals. In this way it is possible to reduce the dependence of oil, a greenhouse gases management can correspond to. In addition, fructose can obtain in a high yield from 5 methylol -2- furfurals, reaction is terminated, and the effective solvent number and catalyst of removing can be reused.
