The invention relates to a process for purifying an ionic liquid, which comprises the steps (a) partial crystallization of the ionic liquid from its melt and (b) separation of the crystals from the residual melt.

Purification of ionic liquids

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.

Method for purifying cyclic ketones

The present application relates to a process for reacting a composition I comprising at least one aldehyde with hydrogen in the presence of a catalyst in at least one main reactor and at least one postreactor, wherein at least 50% of the fresh hydrogen fed to the reaction system is fed into at least one postreactor. In a preferred embodiment, composition I comprises at least one further organic compound.
