| titleOfInvention | Preparation method and catalytic application of sulfonic group covalent modified vacancy polyacid composite material |
| abstract | The invention discloses a preparation method and catalytic application of a sulfonic group covalent modified vacancy polyacid composite material. The preparation method comprises the following steps: covalently modifying (3-mercaptopropyl) trimethoxysilane to the delocalized polyacid; then tetrabutylammonium bromide is used for wrapping the vacancy polyacid for curing; and finally, oxidizing and sulfonating by using hydrogen peroxide and sulfuric acid, and converting sulfydryl into a sulfonic acid group to obtain the sulfonic acid group covalent modified vacancy polyacid composite material. The invention solves the problems that the polyacid is easy to lose in the acid catalysis process, the acidity is reduced, high temperature (100 ℃ and 220 ℃) is needed, the cost is high, the reaction time is long (>10h), and the like. The catalyst can be used as an environment-friendly acid catalyst to be applied to the conversion process of biomass resources, realizes the synthesis of biodiesel and biomass resources 5-HMF under mild conditions, has high-efficiency activity and selectivity, and realizes the high-efficiency recovery and utilization of the catalyst. |
