Abstract
<D>"REMOçãO DE COMPOSTOS REDUTORES DE PERMANGANATO E IODETOS DE ALQUILA DE UM FLUXO DE PROCESSO DE CARBONILAçãO"<D>. é revelado um método para produção de ácido acético com elevada pureza. Embora descrita em relação àquele produzido por um processo de carbonilação com baixo teor de água a presente invenção é aplicável a outros mecanismos para produção de ácido acético que resulta na formação de compostos redutores de permanganato como impurezas de acetaldeído, ácido propiónico, e iodeto de alquila em fluxos de processo intermediário. Verificou-se que os compostos redutores de permanganato e iodetos de alquila podem ser convenientemente removidos de uma fase leve de um fluxo intermediário no processo de reação empregando um processo de destilação múltipla acoplado a uma extração opcional de acetaldeído. O processo de destilação envolve primeiramente destilar uma fase leve para concentrar os compostos redutores de permanganato, e em particular o aceltadeído, e a seguir separar os compostos redutores de permanganato e iodetos de alquila em uma segunda torre de destilação. A segunda destilação serve para retirar os compostos redutores de permanganato e iodetos de alquila de iodeto de metila, acetato de metila, e mistura de metanol. Como uma terceira etapa opcional, o fluxo destilado duas vezes pode ser orientado para um extrator para remover quaisquer quantidades restantes de iodeto de metila do fluxo de acetaldeído aquoso para obter ácido acético como produto final com pureza superior a 99%.
