Title
(PT) processo e dispositivo para preparação contínua de uma solução aquosa de sais
Abstract
(PT)
resumopatente de invenção: "processo para a preparação de uma solução aquosa de sais". a invenção refere-se a um processo para a preparação contínua de solução de sais, em particular, para a preparação de adipato de hexametilenodiamina e um dispositivo para a execução de um tal processo. de acordo com a invenção propõe-se, em uma primeira etapa reagir uma quantidade subestequiométrica de alcanodiamina em relação ao ácido alcanodicarboxílico na água e em uma subsequente segunda etapa, efetuar uma dosagem posterior com alcanodiamina, em que o ajuste das razões estequiométricas é efetuado através de uma medição do valor de ph a temperatura constante.
