| 摘要 |
The invention relates to a method for purifying a composition (I) containing at least one cyclic ketone having 7 to 16 C atoms. The method encompasses the thermal treatment of the composition (I) with a catalyst containing at least one transition metal and the further purification by a method selected from the group consisting of destillation, extraction and crystallization. The invention also relates to a method for producing cyclododecanone, which includes a purification of this type, and to the use of at least one catalyst containing at least one transition metal for purifying a composition (I) containing at least one cyclic ketone having 7 to 16 C atoms by thermal treatment of the composition (I) with a catalyst that contains at least one transition metal. |
