Abstract

The invention relates to a method for preparing 5-hydroxymethylfurfural with high efficiency, the method takes galactose or a galactose-based carbohydrate as base materials, according to special performance of the galactose aldose, a compound 5-HMF is produced by a two-step method, the method is characterized in that galactose is isomated to tagatose under alkaline environment; and 5-HMF can be degraded by talgatose under high temperature by employing acid catalysis. The test confirms that the conversion rate of 5-HMF in the method is high, the method is easy and simple to operate, energy consumption is little, cost is low, and the method has good application prospect.

Description

Technical field

[0001] The invention belongs to the technical field of biomass energy, and specifically relates to a method for preparing the platform compound 5-hydroxymethylfurfural (5-HMF) using galactose as a base material. Background technique

[0002] With the increasingly serious problems of global warming and environmental pollution caused by the extensive use of fossil energy, the development and utilization of sustainable biomass resources has attracted more and more attention. Biomass resources are organic carbon resources that exist in large quantities in nature. Through appropriate conversion methods, biomass resources can provide fuels, high-quality chemicals, new materials, etc.

[0003] Biomass is mainly composed of sugars, lignin, fatty acids, lipids and proteins, with sugars accounting for the largest proportion. Sugars use hexose and pentose as basic units, including cellulose, hemicellulose, starch, etc. Among them, the compound 5-hydroxymethylfurfural (...
