The present invention relates to 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),
(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) in order to obtain a composition (A2), and
(b) distillative treatment of the composition (A2) from step (a2) in order to obtain a composition (B), comprising
the at least one cyclic compound with Z cycles and 7 to 16 carbon atoms with a keto group and
less than 1.0% by weight of the at least one compound with Z−1 cycles and 7 to 16 carbon atoms with at least one aldehyde group,
where Z can be 1, 2, 3 or 4.
本发明涉及一种制备至少一种具有Z个环和7到16个碳原子的含酮基的环状化合物的方法,至少包括以下阶段:(a1)将含有至少一种具有Z个环和7到16个碳原子以及至少两个C—C双键的环状烯烃的组合物(A)氧化,通过二氧化二氮,得到组合物(A1);(a2)从组合物(A1)中分离出至少一种具有Z个环和7到16个碳原子以及至少两个C—C双键的环状烯烃,以获得组合物(A2);以及(b)对来自步骤(a2)的组合物(A2)进行蒸馏处理,以获得组合物(B),包括具有Z个环和7到16个碳原子的至少一种含酮基的环状化合物,以及少于1.0%的重量的至少一种含有Z−1个环和7到16个碳原子且至少一个醛基的化合物,其中Z可以为1、2、3或4。
