Abstract

<B>REMOçãO DE IMPUREZAS DE CARBONILA DE UM FLUXO DE PROCESSAMENTO DE CARBONILAçãO<D> Um processo para reduzir as impurezas de carbonila em uma reação de carbonilação para a produção de ácido acético é descrito. O fluxo de reciclagem do iodeto de metila é direcíonado a um reator de carbonilação para carbonilar o metanol ou acetato de metila em ácido acético, é tratado para remover as impurezas de carbonila reagindo o fluxo do iodeto de metila formado na reação com um composto aquoso amino, o qual reage com as carbonilas para formar derivados nitrogenados solúveis em água, separando a fase orgânica de iodeto de metila de uma fase aquosa derivativa e destilando a fase de iodeto de metila para remover impurezas mais pesadas. O tratamento do fluxo de reciclagem do iodeto de metila no reator de carbonilação foi encontrado como grande redutor das carbonilas presentes no produto do ácido acético. A formação de nitrila dos derivados nitrogenados durante a destilação pode ser minimizada adicíonando água ao sistema.
