Abstract:
The present invention relates to a process for purifying a composition (I) comprising at least one cyclic ketone having from 7 to 16 carbon atoms, which comprises thermal treatment of the composition (I) with a catalyst comprising at least one transition metal and further purification by means of a process selected from the group consisting of distillation, extraction and crystallization. Furthermore, the present invention relates to a process for preparing cyclododecanone, which comprises such a purification, and the use of at least one catalyst comprising at least one transition metal for purifying a composition (I) comprising at least one cyclic ketone having from 7 to 16 carbon atoms by thermal treatment of the composition (I) with a catalyst comprising at least one transition metal.
