Abstract

"PROCESSO PARA A PREPARAçãO DE POLIAMINAS DA SéRIE DIFENILMETANO COM BAIXA PROTONIZAçãO". A presente invenção refere-se a um processo para a preparação de poliaminas da série difenilmetano, no qual a) anilina e formaldeído são reagidos em uma razão molar de 1,5:1 até 6:1 na presença de um catalisador ácido a temperaturas de 20<198>C até 100<198>C, sendo ajustado um teor de água na mistura de reação ácida de < 20% em peso e um grau de protonização de < 15% e b) a temperatura da reação é elevada para valores de 110<198>C até 250<198>C, quando a razão das partes em peso de p-aminobenzilanilina para 4,4<39>-MDA na mistura de reação ácida não alcança um valor de 1,00.
