biomass fuel | 2,5-dimethylfuran (DMF,2,5-DMF) is a biomass-derived chemical and is the most widely studied fuel alternative. It has many excellent properties similar to gasoline. DMF can be miscible with gasoline or used alone. Compared with biofuel ethanol, which is easily soluble in water, difficult to store and has low combustion performance, DMF is considered as a biomass fuel with more development prospects. |
application prospect | 2,5-furandicarboxylic acid (FDCA) is one of the 12 "platform compounds" of the U.S. Department of Energy and has broad application prospects. Its structure is similar to that of terephthalic acid, and it is considered to replace terephthalic acid as an important raw material for the manufacture of polyester plastics, and to manufacture a new generation of polyterephthalate-like (PET) biodegradable plastics; Its structure has the characteristics of pentacyclic bifunctional groups. Compared with the six-membered ring structure of terephthalic acid, it has an asymmetric molecular arrangement, so it can also be used to synthesize optical/gas barrier special functional polymer materials; 2,5 furandicarboxylic acid can also be used as an important intermediate for other fine chemicals, drugs and pesticides. Therefore, the preparation of 2, 5-furandicarboxylic acid is considered to be a very representative sustainable biotransformation process to replace petroleum production, with great application prospects and potential. |
Preparation | At present, DMF is mainly obtained by hydrogenation/hydrogenolysis of 5-hydroxymethylfurfural (HMF) catalyzed by metal catalysts, and most of the catalysts include Palladium, ruthenium and other precious metals. In recent years, there have been some reports on the catalysis of non-precious metals such as nickel, cobalt, copper and iron. 2,5-DMF can also be efficiently produced from fructose in one pot. |
