OPTIMISED LIQUID-PHASE OXIDATION Russian patent published in 2009 - IPC B01J19/24 

FIELD: chemistry.

SUBSTANCE: invention refers to the optimised method and to the device for liquid-phase oxidation of aromatic compounds. The oxidation in liquid phase of the multiphase reaction is carried out in the bubble column reactor. The reaction zone includes the lower and upper sections. The lower section has the first maximal area of horizontal cross section, and the upper one - the second maximal area of horizontal cross section. The first maximal area of horizontal cross section is at least at approximately 10% exceeds the second maximal area of horizontal cross section which provides more efficient and economical reaction implementation at relatively low temperatures.

EFFECT: providing of more efficient and economical reaction implementation at relatively low temperatures.
