摘要：
The invention relates to a method for the production of polyamides from amino nitriles and water, (1) by reacting aminonitriles with water at a temperature of 180 - 350 °C and a pressure of 30 - 120 bar adjusted in such a way that in addition to a liquid phase, a gaseous phase is also present in the first reaction step; (2) relaxation of the reaction mixture obtained in the first reaction step via an evaporator zone or adiabatically with removal of water and ammonia in a second reaction step and (3) post-condensation in the second reaction step at a pressure 0.1 mbar to 5 bar at a temperature of 230 - 320 °C.
