Embodiment 1
[0022] In a Φ30mm metal tubular reactor with a total length of 2m, 731.4g / h (10mol / h) of diethylamine, 88.1g / h (2.0mol / h) of ethylene oxide, and Catalyst zinc chloride 7g / h was added continuously, cooling water at 25°C was introduced into the jacket of the reactor, and the flow rate of cooling water was adjusted to keep the reaction temperature basically constant at 50±5°C. The composition of the final analysis reaction liquid is: DEA70.9%, catalyst 0.8%, DEEA28.1%, high boiler 0.2%.
Embodiment 2
[0024] In a Φ30mm metal tubular reactor with a total length of 2m, 731.4g / h (10mol / h) of diethylamine, 176.2g / h (4.0mol / h) of ethylene oxide, and Catalyst zinc chloride 7g / h was added continuously, cooling water at 25°C was introduced into the jacket of the reactor, and the flow rate of cooling water was adjusted to keep the reaction temperature basically constant at 50±5°C. The composition of the final analysis reaction liquid is: DEA48.6%, catalyst 0.7%, DEEA49.2%, high boiling substances 1.5%.
Embodiment 3
[0026] In a Φ30mm metal tubular reactor with a total length of 2m, 731.4g / h (10mol / h) of diethylamine, 88.1g / h (2.0mol / h) of ethylene oxide, and Catalyst ferric chloride 7g / h was added continuously, cooling water at 25°C was passed into the jacket of the reactor, and the flow rate of cooling water was adjusted to keep the reaction temperature basically constant at 50±5°C. The composition of the final analysis reaction liquid is: DEA71.1%, ethylene oxide 0.1%, catalyst 0.8%, DEEA27.8%, high boiler 0.2%.
