Abstract

"PROCESSO PARA A PREPARAçãO DE POLIISOCIANATOS DA SéRIE DIFENILMETANO MEDIANTE FOSGENAçãO DE POLIAMINA NãO-NEUTRALIZADA DA SéRIE DIFENILMETANO". A invenção refere-se a um processo para a preparação de poliisocianatos da série difenilmetano, no qual a) se reage anilina e formaldeído na presença de HCI para formar uma mistura de produto contendo poliaminas da série difenilmetano, HCI, anilina e água, e depois b) se remove anilina e água excessiva por destilação, sendo que se obtém uma mistura de produto contendo poliaminas da série difenilmetano, HCI bem como anilina com um teor de no máximo 10% em peso com relação às poliaminas e água com um teor de no máximo 5% em peso com relação às poliaminas, e depois c) se fosgena a mistura de produto.
