25Dimethylfuran

2,5-Dimethylfuran (2,5-DMF) is an aromatic heterocyclic compound derived from furan. Its molecular formula is C6H8O and its molecular weight is about 96.1 g/mol. The structure comprises a five-membered furan ring with methyl groups at the 2- and 5-positions, giving a colorless, volatile liquid at room temperature.

Production and sources: 2,5-DMF is mainly produced from biomass. A common route involves catalytic conversion of 5-hydroxymethylfurfural (HMF), which is formed by dehydration of sugars such as glucose and fructose. In typical sequences, HMF is hydrogenated and deoxygenated to yield 2,5-DMF. Alternative methods include hydrogenation of furfural derivatives. The renewable origin of HMF positions 2,5-DMF as a potential platform chemical for fuels and value-added chemicals.

Properties and applications: 2,5-DMF has relatively high energy content among biofuels and shows favorable octane characteristics, making it a candidate for blending with gasoline. It is also studied as a feedstock for polymers, fragrances, and specialty solvents. The compound is flammable and should be handled with standard laboratory or industrial safety practices to minimize exposure and ignition risk.
