| titleOfInvention | Vinyl acetate catalyst and preparation method thereof |
| abstract | The present invention relates to vinyl acetate catalysts, mainly solve the problems, such as that the activity and selectivity of existing vinyl acetate catalyst is low.The present invention is by using vinyl acetate catalyst, with SiO 2 、Al 2 O 3 Or mixtures thereof be carrier, load active component includes Metal Palladium, metallic gold, alkali metal acetate and at least one of the compound 1 being shown below and compound 2 dendrimer compound, and the content of palladium is 1~12g/L in catalyst, the content of gold is 0.1~10g/L, the content of alkali metal acetate is 10~100g/L, dendrimer compound content is 0.1~2.0g/L；Wherein Et 1 ~Et 16 It is independently selected from C 1 ~C 3 Alkyl；The dendrimer compound is to be added after impregnating palladium compound and gold compound in the preparation process of catalyst and before the reduction step. |
