Abstract

<B>"PROCESSO PARA PREPARAçãO DE UM SAL DE DIAMINA/áCIDO DICARBOXìLICO"<D> A presente invenção fornece um processo para fabricação direta de um sal de diamina/ácido dicarboxílico com baixo teor de água. O processo inclui a reação de uma diamina com um ácido dicarboxílico, a fim de formar um sal de diamina/ácido dicarboxílico. A reação entre a diamina e o ácido dicarboxílico é realizada na presença de cerca de 0,5% a 25% em peso de água, com base no peso da mistura da reação, fornecendo ao mesmo tempo condições tais na mistura de reação que a mistura de reação apresenta-se em forma de particulado substancialmente sólido.
