Abstract

"PROCESSO PARA PRODUçãO DE DIAMINODIFENILMETANOS". A presente invenção refere-se a um processo para produção de diaminodifenilmetano (MDA), com alto conteúdo de monómeros, com um baixo conteúdo orto, por transformação catalisada em ácidos sólidos de um produto de condensação (o chamado aminal ou N,N-difenilmetilenodiamina) de anilina e formalina ou um outro agente fornecedor de grupos metileno apropriado, tal como trioxano ou p-formaldeído, caracterizado pelo fato de que é usada anilina, que contém menos de 100 ppm de aminas alifáticas.
