METHOD OF OXIDISING SATURATED CYCLIC HYDROCARBONS WITH OXYGEN Russian patent published in 2009 - IPC C07C27/12 C07C35/08 C07C29/50 C07C49/403 C07C45/33 C07C409/14 C07C407/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of continuous oxidation of saturated cyclic hydrocarbons using oxygen, into a mixture of hydroperoxide, alcohol and ketones. The method involves feeding into the lower part of a column and in parallel flow, a stream of oxidisable liquid hydrocarbon and a gas stream containing oxygen, and degassing the liquid phase in the upper part of the column by forming a gas dome and extraction of the degassed liquid phase. The gas containing oxygen is let into different compartments of the column, and into the dome and/or liquid phase at the level of the degassing zone, or directly above. A stream of non-oxidising gas with output sufficient for maintaining concentration of oxygen in the gas layer at the level of volume concentration, less than or equal to the upper limiting concentration of oxygen is supplied.

EFFECT: possibility of implementing a method with high selectivity on an explosion safe level.
