Abstract
The present invention relates to a production of 1,3-butadiene and methacrolein simultaneously by catalytic oxidation of mixed butenes composed of butene-1, cis-2-butene, trans-2-butene (unless otherwise mentioned, these three butenes will referred to as n-butenes hereinafter) and iso-butylene more particularly, this invention relates to a process for preparing 1, 3-butadiene and methacrolein simultaneously in high yields by oxidizing the mixed butenes mainly composed of n-butenes and isobutylene with molecular oxygen at an elevated temperature in the presence of a catalyst having the empirical formula:
