Abstract
Disclosed are a joint production method and device for aziridine, piperazine and triethylenediamine. The method comprises: reaction 1, preparing piperazine and triethylenediamine by taking ethanol amine as a raw material under the existence of a cyclamine catalyst; reaction 2, preparing aziridine by taking the ethanol amine as the raw material under the existence of a catalyst B; and taking heat released in the reaction 1 as a heat source of heat absorption in the reaction 2. The device comprises a reactor 1 for carrying out the reaction 1 and the heat exchange between reaction materials of the reaction 1 and the raw material of the reaction 2 and a reactor 2 for carrying out the reaction 2. According to the present invention, the same raw material, namely the ethanol amine is adopted, aziridine, piperazine and triethylenediamine can be produced in a joint manner, the heat released in the reaction 1 is used for preheating materials in the reaction 2, so that heat coupling between the reactions is implemented, energy conservation is facilitated and competitiveness of the device is improved.
