ABSTRACT:
The invention is directed to a liquid phase oxidation process, wherein a first oxygen-containing gas is injected into the lower portion of a bubble column reactor vessel containing an oxidizeable organic liquid. A second oxygen-containing gas is further injected into the reactor at a point or points wherein the liquid is substantially depleted in dissolved oxygen prior to said injection. Oxygen from both the first and second oxygen-containing gases is used to oxidize the organic liquid.
