Palladium/carbon dioxide cooperative catalysis for the production of diketone derivatives from carbohydrates

The one-pot production of industrially valuable diketone derivatives from carbohydrates is achieved through a bifunctional catalytic process. In particular, Pd/C-catalyzed hydrogenation of HMF in water and under CO 2 affords 1-hydroxypentane-2,5-dione with up to 77 % yield. The process is also eligible starting from fructose and inulin, affording 1-hydroxyhexane-2,5-dione with 36 % and 15 % yield, respectively. The key of the process is reversible in situ formation of carbonic acid, which is capable of assisting Pd/C during the hydrogenation reaction by promoting the dehydration of carbohydrates and the ring-opening of furanic intermediates. Interestingly, by changing the reaction medium from H2O to a H2O/THF mixture (1:9), it is possible to switch the selectivity of the reaction and to produce 2,5-hexanadione with 83 % yield. Within the framework of sustainable chemistry, reactions presented in this report show 100 % carbon economy, involve CO 2 to generate acidity, require water as a solvent, and are conducted under rather low hydrogen pressures (10 bar).

CONVERSION OF CARBOHYDRATES TO HYDROXYMETHYLFURFURAL (HMF) AND DERIVATIVES

A method of producing substantially pure HMF, HMF esters and other derivatives from a carbohydrate source by contacting the carbohydrate source with a solid phase catalyst. A carbohydrate starting material is heated in a solvent in a column and continuously flowed through a solid phase catalyst in the presence of an organic acid, or heated with the organic acid and a solid catalyst in solution to form a HMF ester. Heating without organic acid forms HMF. The resulting product is purified by filtration to remove the unreacted starting materials and catalyst. The HMF ester or a mixture of HMF and HMF ester may then be oxidized to 2,5-furandicarboxylic acid (FDCA) by combining the HMF ester with an organic acid, cobalt acetate, manganese acetate and sodium bromide under pressure. Alternatively, the HMF ester may be reduced to form a furan or tetrahydrofuran diol.
