Abstract

PURPOSE: To continuously obtain the product from the bottom of a reactor which is equipped with a partition rotating with an agitator, by feeding p-xylene to the top and an oxygen-containing gas to the bottom of the reactor in preparing terephthalic acid by the liquid phase oxidation of the p-xylene.
