Abstract

Se preparan poliamidas a partir de aminonitrilos y agua por medio de: 1) hacer reaccionar el aminonitrilo con agua a una temperatura de 180 a 350 degree C y a unapresion tal en el rango de 30 aa 120 bar, que se encuentra presente una fase gaseosa así como t ambién una fase líquida, en una primera etapa de reaccion, (2)expandir la mezcla de reaccion obtenida en la primera etapa de reaccion a través de una zona del evaporador o adiabáticamente con remocion de agua y amoníacoen una segunda etapa de reaccio n, y (3) condensar posteriormente en la segunda etapa de reaccion a desde 0,1 mbar a 5 bar y de 230 a 320 degree C.
