Abstract

The results of testing a bubble column reactor in the oxidation of cyclododecane by air oxygen in the presence of boric acid at a temperature of 160–165°C and atmospheric pressure are given. A characteristic feature of the multistage column reactor is a number of flow circuits organized via gas-lift pipes arranged above each other. The solid phase (catalyst) is fed at the top into the upper flow circuit and further distributed among all the flow circuits over the liquid volume. The reactor may find applications in catalytic reactions and continuous processes of dissolution, flotation, contact crystallization, and hydraulic classification.
