Title:
PREPARATION OF 2,5-FURAN DIMETHANOL BY TRANSFER HYDROGENATION
Document Type and Number:
WIPO Patent Application WO/2022/178955
Kind Code:
A1
Abstract:
Disclosed is a method for preparing 2,5-furan dimethanol by transfer hydrogenation, comprising adding a hydroxymethyl functionalized carbon-based compound, a nickel monatomic catalyst, and ethanol into a stainless steel closed reactor, replacing air with nitrogen, and catalyzing 5-hydroxymethylfurfural to prepare 2,5-furan dimethanol. Conditions of catalyzing the hydroxymethyl functionalized carbon-based compound are: the reaction temperature is 130-190°C, the stirring rotating speed is 400-800 rpm, and the reaction time is 1-10 h. The ratio of the 5-hydroxymethylfurfural, the nickel monatomic catalyst, and the ethanol is 0.26 g: 0.03-0.3 g: 5-30 mL. In the present invention, a monatomic catalyst is successfully used to catalyze a carbon-based compound as an alcohol in an ethanol system for the first time, the preparation method for the catalyst used is simple and the raw materials are cheap, and then the method is easy to industrialize; renewable and nontoxic ethanol is used as a hydrogen source for reduction reaction, the reaction process is safe, green, and environmentally friendly, product selectivity is high, the reaction activity turnover frequency (TOF) exceeds those of all non-noble metal catalysts reported so far, and then the method has a great industrial application value.
