| description | The reaction device comprises a reaction kettle, a condenser, a stirrer, a hydrogen inlet pipe, a nitrogen inlet pipe and a pressure gauge are arranged on the reaction kettle, a hydrogen pressure reducing valve and a hydrogen regulating valve are arranged on the hydrogen inlet pipe, and an outlet of the condenser is sequentially connected with a buffer tank and two tail gas absorption tanks. Gas is exhausted from the top of the rear tail gas absorption tank, and the two tail gas absorption tanks are filled with water for absorbing ammonia gas in the tail gas; a circulating pump is arranged between the tank bottom and the tank top of each tail gas absorption tank, and the tail gas absorption tanks form an internal circulation system under the action of the circulating pumps; each connecting pipeline is provided with a control valve used for controlling opening and closing of the corresponding pipeline. By adopting the pressure deamination and exhaust device, the dialiphatic secondary amine is synthesized in on |
