Abstract

The invention provides a catalyst for synthesis of 5-hydroxymethylfurfural and a preparation method of the 5-hydroxymethylfurfural. The catalyst is obtained by fully mixing activated clay and a modifier according to a certain proportion, extruding and forming, uniformly heating, grinding into powder, and sieving by a sample sieve. According to the preparation method, biomass saccharides are used as raw materials, modified activated clay is used as a catalyst, and 5-hydroxymethylfurfural is prepared through catalysis of a high-boiling-point solvent. Results prove that the method is simple and easy to operate, the yield of the 5-hydroxymethylfurfural is high, and the catalyst is environment-friendly, low in cost and easy to separate and recover, and has a good application prospect.

Description

technical field [0001] The patent of the present invention belongs to the field of biomass energy, and specifically relates to a catalyst for synthesizing 5-hydroxymethyl furfural and a preparation method of 5-hydroxymethyl furfural. Background technique [0002] As an important biomass-based monomer, 5-Hydroxymethylfurfural has furan rings, hydroxyl groups and aldehyde groups in its molecule. Many useful compounds and new polymers can be prepared through chemical reactions such as hydrogenation, oxidation, ring opening, hydrolysis and polymerization. Materials, including pharmaceuticals, resin-based plastics, diesel fuel additives, liquid fuels, etc. Therefore, 5-Hydroxymethylfurfural is considered as a bridge compound between natural biomass carbohydrate resources and the petroleum industry, and is listed as one of the ten most valuable platform compounds by the US Department of Energy. [0003] Initially, 5-hydroxymethylfurfural was synthesized from fructose or glucose t...
