Аннотация:The quest to achieve a sustainable supply of both energy and chemicals is one of the great challenges of this century. 5-(Hydroxymethyl)furfural (HMF), the long-known dehydration product of hexose carbohydrates, has become an important nexus for access to both liquid fuels and chemicals. One such biofuel is 2,5-dimethylfuran (DMF), which is a product of HMF hydrogenolysis and contains an energy density 40% greater than that of ethanol. In recent years, much work has been done to effect the chemical conversion of fructose, glucose, cellulose, and even lignocellulosic biomass into HMF in high yield. Here, we provide an overview of methods to access HMF from carbohydrates with the highest potential to reach an industrial scale, along with a discussion of unmet technological needs necessary for commercialization.
