Method for the prevention of post oxidation of methacrolein |
| abstract |
This invention provides a method for the prevention of oxidation of resulting methacrolein immediately after its discharge from a reaction tube upon production of the methacrolein by vapor-phase oxidation of isobutylene, tertiary butanol or methallyl alcohol with a molecular-oxygen-containing gas in the presence of a catalyst. An inert gas and/or recirculated reaction gas or a mixed gas of an inert gas and/or recirculated reaction gas and air is fed and mixed with a reaction product gas immediately after an outlet of the reaction tube. |
