Process for preparing cyclic diamines |
| abstract |
The present invention relates to a process for preparing a cyclic diamine, comprising the reaction of at least one cyclic alkene with a gas mixture (G) comprising dinitrogen monoxide to give at least one cyclic ketone and the subsequent conversion of the at least one cyclic ketone to a cyclic diamine. The invention also relates to the use of a cyclic diamine with primary and secondary amine functions thus obtained to prepare polyamides and polyurethanes. |
