Title:
METHOD FOR CONTINUOUSLY SYNTHESIZING 5-HYDROXYMETHYLFURFURAL BY USING MICROCHANNEL REACTOR
Document Type and Number:
WIPO Patent Application WO/2024/065968
Kind Code:
A1
Abstract:
A method for continuously synthesizing 5-hydroxymethylfurfural by using a micro-channel reactor, which belongs to the technical field of micro-chemical engineering. The method comprises: separately conveying an aqueous glucose solution, which contains FeCl3 and HCl, and methyl butyl ketone to a T-shaped micro-mixer, the T-shaped micro-mixer being in communication with a capillary tube; then enabling an aqueous glucose solution phase and a methyl butyl ketone phase to flow in the capillary tube in a segmented flow manner while performing an HMF synthesis reaction; and collecting a reaction product flowing out of the capillary tube, wherein HMF generated by the reaction is present in an organic phase of the reaction product. The synthesis method is easy to operate, has a controllable process, high product yield, a low by-product amount and a short synthesis period, and is a green method for efficient and continuous synthesis of HMF.
