Preparation method of furfural

Номер: CN116262732A
Автор: CHEN GONGZHE, SUN QIANHUI, ZHENG LUFAN, ZONG BAONING
Принадлежит:

The invention discloses a method for preparing furfural, which comprises the following step of: catalyzing an intramolecular dehydration reaction of xylose-based carbohydrate in a double-liquid-phase reaction medium consisting of a low-boiling-point organic solvent-eutectic solvent by using a chlorine-containing sulfonic acid carbon-based solid acid catalyst. The used solid acid catalyst is high in surface sulfonic acid density and strong in acidity, and the used reaction medium can increase the solubility of xylose-based carbohydrate and the solvation effect on xylose. Through optimization of the catalyst and the reaction medium, the dehydration rate of xylose is effectively improved, the reaction time is shortened, and furfural is prevented from being decomposed due to long-time retention under a high-temperature acidic condition, so that the selectivity of furfural is improved.
