Abstract:
A preparation method of an acidic and hydrophobic Pd/C catalytic material comprises performing a simple treatment with chlorosulfonic acid and trimethylchlorosilane, washing and drying a treatment product to obtain a modified Pd/C catalytic material. A method for preparing 2,5-methylfuran by catalyzing a carbohydrate with modified Pd/C comprises: dissolving the carbohydrate in alcohol, allowing a reaction to proceed with modified Pd/C as a catalyst and polymethylhydrosiloxane as a hydrogen donor at a temperature of 80˜140° C. for 1-5 hours, and performing centrifugation to separate the catalyst from the product. The content of the modified Pd/C content is 1-3 mol % relative to the carbohydrate; the polymethylhydrosiloxane amount is equivalent to 4-10 times the carbohydrate amount, and the carbohydrate concentration in the alcohol is 2-6 wt %. The method overcomes the defect of being difficult to prepare the 2,5-methylfuran by directly catalyzing the carbohydrate, and features moderate reaction conditions and high activity.

Claim (Index 11):
The method of preparing 2,5-methylfuran by directly catalyzing carbohydrates with modified Pd/C according to  claim 7 , wherein the mixture solution further comprises an alcohol as a solvent, and an concentration of the carbohydrates relative to the alcohol is about 2-6 wt %.
