Abstract:
1. A process for preparing at least one cyclic compound with Z cycles and 7 to 16 carbon atoms with a keto group, at least comprising the stages: (a1) oxidation of a composition (A), at least comprising one cyclic olefin with Z cycles and 7 to 16 carbon atoms and at least two C—C double bonds, by means of dinitrogen monoxide to give a composition (A1), at least comprising (a2) separating off the at least one cyclic olefin with Z cycles and 7 to 16 carbon atoms with at least two C—C double bonds from the composition (A1) from stage (a1) in order to obtain a composition (A2), at least comprising (b) distillative treatment of the composition (A2) from step (a2) in order to obtain a composition (B), comprising where Z can be 1, 2, 3 or 4.
