Method for producing unsaturated aldehyde and/or unsaturated carboxylic acid |
| abstract |
The present invention provides a method for producing an unsaturated aldehyde and/or an unsaturated carboxylic acid that can improve the effective yield even in a high-load reaction and can operate stably over a long period of time. A method for producing an unsaturated aldehyde and/or an unsaturated carboxylic acid, comprising the steps of stacking two or more catalyst layers containing a composite metal oxide catalyst in the direction of the tube axis under specific conditions to perform multi-layer filling, and the tube axis The catalyst layer closest to the gas outlet side contains a catalyst further comprising a compound represented by a specific composition formula. |
