Copper-promoted shell catalyst for producing alkenyl carboxylic acid esters |
| 摘要 |
A method for producing a shell catalyst which is suitable for the synthesis of alkenyl carboxylic acid esters, in particular for producing vinyl acetate monomer (VAM) from ethylene or allyl acetate monomer from propylene by means of oxy-acetylation. Also, a shell catalyst that can be obtained by the method according to the invention, as well as the use of the shell catalyst produced using the method for producing alkenyl carboxylic acid esters, in particular vinyl acetate monomer (VAM) and allyl acetate monomer. |

1. A method for producing a shell catalyst, in which the following steps are carried out:
(a) applying a water-soluble acetate compound comprising acetate anions to a support body; and (b) sequentially or simultaneously applying a Pd precursor compound and an Au precursor compound to the support body obtained after step (a);wherein in one of steps (a) and (b) a Cu and/or Sn precursor compound is additionally applied to the support body. |
