摘要:
The present invention relates to a method for selective hydrogenation of furan-2,5-dialdehyde (DFF) into 2,5-di(hydroxymethyl)furan (DHMF) and into 2,5-di(hydroxymethyl)tetrahydrofuran (DHMTHF). In relation to the prior art, which uses C6 sugars or 5-hydroxymethyl furaldehyde (5-HMF) as raw materials, said method can be performed at low temperatures (lower than 120 °C, preferably 80 °C), while consuming low amounts of catalyst relative to the initial reagent (in particular less than 5 %, preferably less than 2 % relative to the weight of the reagent). The heterogeneous catalyst used can also be recycled from one reaction to another. Finally, the choice of experimental conditions enables the selective formation of DHMF or DHMTHF.
摘要:
The present invention relates to a method for synthesising 2,5-furandicarboxylic acid (FDCA) from furan-2,5-dialdehyde (DFF). Said method is industrially applicable due to the simplicity and availability of the reagents used, and due to the experimental conditions on which said method is based: the method requires low temperatures and enables a reaction under atmospheric pressure, the reaction times being relatively short. Furthermore, the method does not lead to the formation of salts that need to be treated downstream from the method, and the catalytic ratio relative to the initial product is particularly low.
