Latest Patents

Zhao Wenfeng holds a patent for a method of preparing 2,5-dimethylfuran by directly catalyzing carbohydrates using modified Pd/C. This preparation method involves creating an acidic and hydrophobic Pd/C catalytic material through a simple treatment with chlorosulfonic acid and trimethylchlorosilane. The process includes washing and drying the treatment product to obtain the modified Pd/C catalytic material. The method allows for the dissolution of carbohydrates in alcohol, followed by a reaction with modified Pd/C as a catalyst and polymethylhydrosiloxane as a hydrogen donor at temperatures ranging from 80 to 140 degrees Celsius for 1 to 5 hours. The catalyst is then separated from the product through centrifugation. This innovative approach overcomes previous challenges in preparing 2,5-methylfuran and features moderate reaction conditions and high activity.
