Abstract
The invention relates to a method for producing substituted monocyclic ketones C4-C20. The inventive method is based on the reaction of a liquid phase oxidation of substituted monocyclic alkenes C4-C20 by nitrogen oxide or by the mixture thereof with an inert gas. The process is carried out at a temperature ranging from 20 to 350 °C and a pressure of nitrogen oxide ranging from 0,01 to 100 atm. The inventive process ensures the high selectivity with respect to target products, the explosion safety at work and is promising for industrial use.
