| titleOfInvention | Zirconium silicate modified sulfonic acid grafted mesoporous silica catalyst, and preparation method and application thereof |
| abstract | The invention relates to a zirconium silicate modified sulfonic acid grafted mesoporous silica catalyst, a preparation method and application thereof. The preparation method of the zirconium silicate modified sulfonic acid grafted mesoporous silica comprises the steps of firstly adding a template agent, a structure directing agent, a silicon source and a zirconium source, carrying out two-step crystallization hydrothermal synthesis on the zirconium silicate modified mesoporous silica, and then adding the sulfonic acid source into a certain solvent for modification. The preparation process of the zirconium silicate modified sulfonic acid grafted mesoporous silicon oxide is environment-friendly, synthesized in a weak acid environment and uniform and adjustable in aperture. And the method can efficiently and stably catalyze olefin and carboxylic acid to synthesize carboxylic ester with high conversion rate and high selectivity under the conditions of small catalyst dosage, high temperature and no solvent, improve the atom utilization rate of the atom economic reaction, effectively reduce the energy consumption for separating reaction products and reduce the equipment investment. |
