Abstract

The invention discloses a synthetic method of 2,5-furan dimethanol and an etherified product of 2,5-furan dimethanol and relates to 2,5-furan dimethanol. The synthetic method comprises the following steps of: adding organic alcohol into a reaction substrate; putting the obtained mixture as a raw material in a high pressure reaction kettle; adding a certain amount of a molecular sieve supported catalyst; and performing a heating reaction to obtain 2,5-furan dimethanol and the etherified product of 2,5-furan dimethanol. By using alcohol as a hydrogen donor and a reaction substrate, no external hydrogen source does not needed. By adjusting the acid-base property of a catalyst through an active metal component, 2,5-furan dimethanol can be obtained by selectively catalyzing transfer hydrogenation of 5-hydroxymethylfurfural or 2,5-dialkoxyl methyl furan is obtained by further etherification. The catalyst is cheap and easily available and good in repeatability, no excessively hydrogenated product exists, and the whole reaction is hydrogenated in a hydrogen environment, and the synthetic method has relatively strong operating safety of industrial production and very good industrial application potential.

Description

technical field [0001] The present invention relates to 2,5-furandimethanol, in particular to a method for synthesizing 2,5-furandimethanol and its etherified product using two-component active metal-supported molecular sieves to catalyze the transfer hydrogenation of 5-hydroxymethylfurfural . Background technique [0002] As a biomass-based furan derivative compound, 2,5-furandimethanol has a very wide application potential, and has attracted more and more attention from academia and industry in recent years. 2,5-furandimethanol can be used as a raw material to synthesize pharmaceutical intermediates, nucleoside derivatives, crown ethers and furans, and can also be used as solvents, softeners, wetting agents, binders, surfactants, synthetic plasticizers, etc. Second, it can be used as a monomer to synthesize polyester, polyurethane and other polymeric materials, reduce the content of volatile organic compounds in clothing coatings, and is expected to completely or partiall...
