    摘要: The invention relates to a method for producing at least one cyclic compound comprising Z cycles and between 7 and 16 C atoms with one carbonyl group, said method comprising at least the following steps: (a1) oxidation of a composition (A), at least containing one cyclic olefin with Z cycles and between 7 and 16 C atoms and at least two C-C double bonds, using dinitrogen monoxide, to obtain a composition (A1); (a2) isolation of the at least one cyclic olefin comprising Z cycles and between 7 and 16 C atoms with at least two C-C double bonds from the composition (A1) to obtain a composition (A2); and (b) distillatory treatment of the composition (A2) from step (a2) to obtain a composition (B) containing the at least one cyclic compound with Z cycles and between 7 and 16 C atoms with one carbonyl group and less than 1.0 wt. % of the at least one compound comprising Z-1 cycles and between 7 and 16 C atoms with at least one aldehyde group. According to the invention, Z can be 1, 2, 3 or 4.
