Abstract

"PROCESSO PARA A PRODUçãO DE DIISOCIANATO DE 2,4<39>-METILENODIFENILA MUITO PURO". A presente invenção refere-se a um processo para a produção de frações de MDI contendo 2,4<39>-MDI, e em que o componente de 2,2<39>-MDI da produção de MDA é largamente removido da mistura de isómero. Os produtos de MDI monoméricos altamente reativos podem ser produzidos desta maneira. Estes produtos de MDI são caracterizados em seu processamento por emissões significantemente reduzidas de monómeros de MDI.
