| description | The invention discloses a method for preparing furyl alcohol through hydrolysis reaction in a maltol Grignard section. The method comprises the following steps: (1) injecting water into a Grignard hydrolysis elevated tank; (2) dropwise adding water into an addition reagent to carry out hydrolysis reaction at the dropwise adding speed of 150L/h for 3 hours, and controlling the reaction temperatureto be 0-30 DEG C in the reaction process; (3) carrying out hydrolysis reaction to obtain a furfuryl alcohol solution; and (4) converging all the tail gas of the whole maltol Grignard section, recovering through an absorption tower, taking water as a solvent in the absorption tower, returning tower washing water of the absorption tower to the step (1) as hydrolysis water, injecting the hydrolysis water into the Grignard hydrolysis elevated tank, and recycling. The method saves the production cost, reduces the environmental pollution and improves the conversion rate of the Grignard hydrolysis section.
