Abstract

"PROCESSO PARA A PREPARAçãO DE METILENODIANILINA PELA REAçãO DE ANILINA COM FORMALDEìDO NA PRESENçA DE CATALISADORES áCIDOS, MISTURA COMPREENDENDO METILENODIANILINA, PROCESSOS PARA A PREPARAçãO DE POLIISOCIANATOS PELA FOSGENAçãO DE POLIAMINAS, PARA A PREPARAçãO DE METILENOBIS(FENIL ISOCIANATO, E PARA A PREPARAçãO DE MDI MONOMéRICO E MDI POLIMéRICO, E, POLIISOCIANATO" Processo para a preparação de metilenodianilina pela reação de anilina com formaldeído na presença de catalisadores ácidos e que compreende, em um processo semicontínuo, introduzir anilina com ou sem o catalisador ácido, alimentar o formaldeído com ou sem o catalisador ácido através de um elemento de mistura, para um circuito no qual a anilina com ou sem o catalisador ácido e com ou sem formaldeído previamente adicionado é circulada e, após alimentar pelo menos 50 % da quantidade total do formaldeído a ser alimentado, aquecer a mistura de reação até uma temperatura acima de 75° C. Além disso a invenção está relacionada a processo para a preparação de poliisocianatos pela fosgenação de aminas que podem ser obtidas desta forma e a poliisocianatos que podem ser obtidos por este processo.
