2,5-Dimethylfuran is a organic compound that is classified as a substituted furan. It is a colorless liquid that is insoluble in water but soluble in common organic solvents. It is obtained from furfural, an important renewable, non-food biomass, through a series of chemical reactions.

Structure and Properties[edit | edit source]

2,5-Dimethylfuran is a five-membered ring with two methyl groups attached to the 2 and 5 positions of the furan ring. The furan ring consists of four carbon atoms and one oxygen atom. The molecular formula of 2,5-dimethylfuran is C6H8O.

The compound has a boiling point of 92-93 °C and a melting point of -85.6 °C. It is less dense than water and its vapors are heavier than air.

Production[edit | edit source]

2,5-Dimethylfuran is produced from furfural through a series of chemical reactions. Furfural is obtained from lignocellulosic biomass, which is a renewable, non-food resource. The production process involves the hydrogenation of furfural to furfuryl alcohol, followed by acid-catalyzed dehydration to 2,5-dimethylfuran.

Applications[edit | edit source]

2,5-Dimethylfuran has potential applications as a biofuel. It has a higher energy density and octane rating than ethanol, making it a promising alternative fuel. It is also used as a solvent and an intermediate in the production of other chemicals.

Safety[edit | edit source]

2,5-Dimethylfuran is flammable and its vapors can form explosive mixtures with air. It can cause irritation to the eyes, skin, and respiratory tract.
