Abstract
Methacrolein is produced by catalytically oxidizing t-butyl alcohol with oxygen by using a catalyst system of MoSbBiFeNi-alkali. Propylene or isobutylene can also be catalytically oxidized with the same catalyst system to produce acrolein or methacrolein. Methacrolein and 1,3-butadiene can simultaneously be produced by catalytically oxidizing a mixture of isobutylene and n-butene with the same catalyst.
