| titleOfInvention | Preparation method of methacrolein |
| abstract | The present invention provides as by the oxidation of isobutylene or t- butanol vapor contact in the presence of a catalyst represented by the Mo12FeaXbYcZdOe manufacturing methacrolein, and the reaction temperature is 300 ℃ ~450 ℃, space velocity of 800hr -1 ~4,000hr - 1 Preferably 900hr -1 to 3,000hr -1 , the concentration of isobutylene or t-butanol is 3 mol.% To 8mol.%, The reaction pressure is 0.5kg to 5kg in absolute pressure, oxygen and reactants (isobutylene or t-butanol) relates to a method for producing methacrolein, in which 2 mol.% to 90 mol.%, preferably 4 mol.% to 90 mol.% of carbon dioxide is injected under conditions of 1.5 to 3.5. |
