OPTIMISED LIQUID-PHASE OXIDATION Russian patent published in 2010 - IPC C07C51/265 B01J10/00 B01J19/24 

FIELD: chemistry.

SUBSTANCE: method involves input of initial material to undergo oxidation, containing the compound to undergo oxidation into the reaction zone of a reactor-type bubble column through several openings for the initial material and a stream of oxidising agent containing molecular oxygen into the reaction zone of the said column through several openings for the oxidising agent, made in the channel of the bubbling chamber for oxidation. Pressure is reduced by a value not more than approximately 0.3 MPa in the said channel. In the second version of the method at least approximately 5 wt % of the said stream of oxidising agent is released from the said channel from top to bottom. The bubble column has a housing which defines the reaction zone which extends along the central axis with maximum diametre (D), the bottom and top levels of which are at maximum distance (L) from each other, and the ratio L:D equals at least approximately 3:1.

EFFECT: efficient and cheap liquid-phase oxidation of compounds.
