A method of contact catalytic reaction by introducing a gas and a liquid into a lower part of a reaction zone comprising a liquid phase and a catalyst-packed bed held therein, where the catalyst-packed bed is a fixed bed.

Method of contact catalytic reaction

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.
