Abstract
"PROCESSO PARA A SEPARAçãO DESTILATIVA DE 6-AMINOCAPRONITRILA DAS MISTURAS CONTENDO 6-AMINOCAPRONITRILA, ADIPODINITRILA E HEXAMETILENODIAMINA". A invenção refere-se a um método para remover, por destilação, 6-aminocapronitrila de misturas que contêm 6-aminocapronitrila, adipodinitrila e hexametilenodiamina, a) removendo-se a hexametilenodiamina da mistura enquanto obtendo-se uma mistura (I) que tenha um teor de hexametilenodiamina menor do que 1 % em peso, b) removendo-se completa ou parcialmente a 6-aminocapronitrila da mistura (I), enquanto obtendo-se uma mistura (II), cujo teor de substâncias que têm um mais elevado ponto de ebulição como 6-aminocapronitrila, sob condições de destilação, e que não podem ser formadas por reações de dimerização quando 6-aminocapronitrila é termicamente tratada, é menor do que 1 % em peso e c) removendo-se completa ou parcialmente da mistura (II) a hexametilenodiamina, que poderia estar presente, enquanto obtendo-se uma mistura (IV), cujo teor de hexametilenodiamina é mais elevado do que aquele da mistura (II) e uma mistura (V) cujo teor de hexametilenodiamina é mais baixo do que aquele da mistura (II).
