Abstract
In a process for preparing methacrolein by oxidation of isobutane, unreacted isobutane is absorbed from a gaseous mixture by absorption in a liquid absorbent and recovered by stripping the absorbent with nitrogen or a mixture of nitrogen and oxygen. The recovered isobutane in admixture with the stripping gas is then recycled to the oxidation reaction.
