Abstract

A one-pot process for the production of 2,5-dimethylfuran from fructose by using Ru/C and a Lewis–Brønsted acid mixture as catalysts.

Abstract

An efficient catalysis system composed of a Lewis–Brønsted acid mixture and Ru/C using N, N-dimethylformamide as a solvent was developed for the one-pot conversion of fructose to 2,5-dimethylfuran (2,5-DMF) via the dehydration/hydrogenolysis sequence. The effects of various reaction parameters, such as solvent, catalyst type, catalyst loading, reaction pressure, temperature and time, on single fructose dehydration, 5-hydroxymethylfurfural (5-HMF) hydrogenolysis and the one-pot conversion of fructose to 2,5-DMF were systematically investigated. The results showed that 2,5-DMF could be successfully produced with a yield as high as 66.3 mol% by using a one-pot method directly from fructose under the optimized reaction conditions, which is by far the highest yield ever reported for the production of 2,5-DMF from fructose through a one-pot strategy. The Ru/C catalyst could be reused at least three times with a slight decrease in 2,5-DMF yield.

Simple chemical transformation of lignocellulosic biomass into furans for fuels and chemicals.

Joseph Binder, Ronald T. Raines (2009)

Lignocellulosic biomass is a plentiful and renewable resource for fuels and chemicals. Despite this potential, nearly all renewable fuels and chemicals are now produced from edible resources, such as starch, sugars, and oils; the challenges imposed by notoriously recalcitrant and heterogeneous lignocellulosic feedstocks have made their production from nonfood biomass inefficient and uneconomical. Here, we report that N,N-dimethylacetamide (DMA) containing lithium chloride (LiCl) is a privileged solvent that enables the synthesis of the renewable platform chemical 5-hydroxymethylfurfural (HMF) in a single step and unprecedented yield from untreated lignocellulosic biomass, as well as from purified cellulose, glucose, and fructose. The conversion of cellulose into HMF is unabated by the presence of other biomass components, such as lignin and protein. Mechanistic analyses reveal that loosely ion-paired halide ions in DMA-LiCl are critical for the remarkable rapidity (1-5 h) and yield (up to 92%) of this low-temperature (
