A US patent was awarded about synthesizing of 2,5-dimethylfuran
Recently, a US patent was awarded to Profs. Hu Li and Zhen Fang, entitled “Hydrophobic palladium/metal organic framework material, preparation method thereof, and application therefor for use in synthesizing 2,5-dimethylfuran” (US 11,584,729 B2, Filed: October 18, 2017, Date of Patent: February 21, 2023, Assignee: Nanjing Agricultural University, Inventors: Zhen Fang, Hu Li; https://patents.justia.com/patent/11584729).
A hydrophobic palladium/metal organic framework (MOF) material, which is a solid catalyst material obtained by taking a porous MOF as a carrier, introducing elementary palladium by means of an immersion-reduction method, and performing polydimethylsiloxane coating layer processing. A method which uses hydrophobic palladium/MOF material to selectively catalyze hexoses to prepare 2,5-dimethylfuran comprises: dissolving a hexose into an alcohol; using the hydrophobic palladium/MOF material as a catalyst and polymethylhydrosiloxane as a hydrogen donor, reacting at 70 to 130 °C. for 0.25 to 12 h under the action of an acidic additive; the concentration of the hexose in the alcohol is 0.2 to 10 wt %, and the total amount of Pd contained in the hydrophobic palladium/MOF material relative to a hexose is 0.1 to 5 mol %.
Hydrophobic palladium/metal organic framework material, preparation method thereof, and application therefor for use in synthesizing 2,5-dimethylfuran. (“疏水性钯/金属有机骨架材料，制备方法及其在合成2,5-二甲基呋喃中的应用”获美国专利)
李虎博士获美国授权发明专利
最近，方真教授和李虎博士获美国授权发明专利。方真，李虎 题为“疏水性钯/金属有机骨架材料，制备方法及其在合成2,5-二甲基呋喃中的应用”（US 11584729 B2，申请日期：2017年10月18日，专利日期：2023年2月21日，受让人：南京农业大学，发明人：方真、李虎；https://patents.justia.com/patent/11584729)。
一种疏水性钯/金属有机框架（MOF）材料，其是通过将多孔MOF作为载体，通过浸渍还原法引入元素钯，并进行聚二甲基硅氧烷涂层处理而获得的固体催化剂材料。一种使用疏水性钯/MOF材料选择性催化己糖制备2,5-二甲基呋喃的方法包括：将己糖溶解于醇中；使用疏水性钯/MOF材料作为催化剂，使用聚甲基氢硅氧烷作为氢供体，在酸性添加剂的作用下，在70至130 °C下反应0.25至12小时；醇中己糖的浓度为0.2至10wt%，并且疏水性钯/MOF材料中所含的Pd的总量相对于己糖为0.1至5mol%。
