Abstract
In yielding diacetoxybutene by feeding butadiene, acetic acid, and oxygen in the presence of a solid catalyst containing palladium, the butadiene can be efficiently reacted to produce diacetoxybutene in high yield by feeding an oxygen-containing gas containing 7 mol % or more oxygen as fine bubbles to a reaction zone containing the solid catalyst.
