| titleOfInvention | A kind of catalyst and preparation method and application thereof |
| abstract | The invention provides a preparation method of a catalyst, which comprises the following steps: calcining strontium phosphate to obtain a strontium pyrophosphate carrier; immersing the strontium pyrophosphate carrier in phosphoric acid for 4 hours, suction filtration, washing and drying to obtain a phosphoric acid modified strontium pyrophosphate carrier; After the phosphoric acid-modified strontium pyrophosphate carrier is mixed with Cs + and calcined, the catalyst of the present invention is obtained. The phosphoric acid-impregnated strontium pyrophosphate-supported cesium catalyst of the invention is simple to prepare, environmentally friendly, low in cost, high in catalytic activity, and has improved catalytic performance for the preparation of 2,3-pentanedione by lactic acid condensation reaction, and has high commercialization develop value. |
