Abstract:
Highly pure triethylenediamine is obtained by a process in which triethylenediamine is freed from high boilers and then the triethylenediamine is vaporized from the mixture thus obtained and is passed into a liquid solvent. The process makes it possible in particular to obtain highly pure solutions of triethylenediamine. Crystallization is generally unnecessary.
