Hi, 

 

I have a patent for the oxidation of isobutylene and it suggested to operate a reactor at 330C. However, the product of the reaction, Methacrolein, has an autoignition temperature of 295C. I am wondering how can the industry operate a reactor at a temperature above the autoignition point? In addition, air is added in excess, therefore, with large amount of oxygen, it will be easier for methacrolein to ignite itself. How is it possible to operate a reactor above the product's autoignition temperature?

Maybe the excess air addition causes the reactor to be too lean to support combustion.
