Abstract: Continuous distillative separation of piperazine from ethylenediamine-piperazine mixture comprises subjecting the piperazine mixture into a cyclic motion, introducing the piperazine mixture into an evaporator unit at 160-170[deg]C, recycling the piperazine mixture into a distillation column and removing the piperazine from the sump of the distillation column after a retention time of approximately 30-60 minutes, where the ethylene diamine is discharged at the upper portion of the distillation column.
