실험 절차
The reactor was maintained at 6 MPa, and 70° C. acetic acid containing butadiene and 70° C. nitrogen gas containing oxygen were continuously introduced into a lower part of the reactor at superficial velocities of 1.8 cm/sec and 1.5 cm/sec, respectively, and passed through the catalyst-packed bed upward. The nitrogen gas containing oxygen was introduced with a sparger so as to form fine bubbles. The liquid and gas introduction was thus continued over 2,700 hours to conduct a reaction for yielding diacetoxybutene. Thereafter, the catalyst was withdrawn through the upper part of the reactor and examined for palladium content. As a result, the palladium content had not decreased at all. Furthermore, the surface of the catalyst withdrawn was examined with an optical microscope (magnification, 50 diameters). As a result, almost no mars formed by friction were observed.
