A process for the liquid Phase oxidation of butane to produce acetic acid and a Reactor for carrying out Said process

摘要

A process for the liquid phase oxidation of butane to produce acetic acid by reacting oxygen and butane in the presence of a decobalt catalyst in a liquid reaction composition in an oxidation reaction zone, which is carried out at a temperature in the reaction zone of the order from 120 to 180 ° C,At the same time, maintain a continuous oxygen concentration in the whole reaction area equivalent to the partial oxygen pressure of more than 2 bars, and a concentrated cobalt catalyst oxidizes the composition of 0 in the liquid feedback, 12% of cobalt weight and its solubility in the liquid reaction component. Suitable reactorThe pretreatment for acetic acid includes two reaction zones, where the first reaction zone can hold the first liquid reaction and is composed in the recovery process. The second reaction zone can hold the second liquid reaction position without any gas / liquid interface and overhead current One gas / liquid interface and one gas head phaseThe first reaction zone is transformed into a gas and / or liquid entry medium and a damping medium suitable for dispersion in the gas / liquid reaction zone of the first entry medium.
