2,5-dimethylfuran (DMF; the abbreviation DMF is however common for the solvent dimethylformamide ) is a heteroaromatic organic - chemical compound . It consists of a furan backbone that is methylated at the carbon atoms in positions 2 and 5.
Extraction and presentation
The starting point for the production of 2,5-dimethylfuran is z. B. Biomass from sugar cane , especially fructose .
use
Dimethylfuran is seen as a potential biofuel that could replace ethanol . Dimethylfuran has a 40% higher energy density than ethanol, so it is comparable to gasoline . It is chemically stable and, unlike ethanol, does not absorb moisture from the atmosphere. It also has a lower tendency to evaporate.
