Abstract

"PROCESSOS CATALISADOS POR COMPLEXO DE METAL-LIGANTE APERFEIçOADOS". Esta invenção se refere a um processo para a estabilização de um catalisador de complexo de metal-ligante de organofósforo contra a desativação em um processo que compreende a reação de um ou mais reagentes na presença de um catalisador de complexo de metal-ligante de organofósforo e, opcionalmente, ligante de organofósforo livre, para produzir um produto de reação fluido compreendendo um ou mais produtos, e em que pelo menos uma parte do processo é conduzida sob condições de separação suficientes para efetuar pelo menos alguma desativação do catalisador de complexo de metalligante de organofósforo, o processo compreendendo a condução da parte do processo que ocorre sob condições de separação na presença de um ou mais alcadienos suficientes para evitar e/ou reduzir a desativação do catalisador de complexo de metal-ligante de organofósforo.
