Abstract

El presente invento se refiere a un método para la producción continua de una solución de sales, en particular para la producción de adipato de hexametilendiamina y a un dispositivo para llevar a cabo un método de este tipo. De conformidad con la invención se propone en una primera etapa hacer reaccionar en agua una cantidad subestequiométrica de alcandiamina en relación al ácido alcandicarboxílico y en una segunda etapa consecutiva llevar a cabo una adición dosificada de alcandiamina adicional, siendo que el ajuste de las relaciones estequiométricas se efectúa por vía de una medición del valor pH a temperatura constante.
