Abstract

processo para a corrodução de anidrido acético e de ácido acético. é exposto um processo para a coprodução de ácido acético e de anidrido acético através da produção, em um primeiro reator de carbonilação, de uma mistura de produto de carbonilação contendo o anidrido acético, removendo a mistura de carbonilação do primeiro reator de carbonilação, contactando a mistura de carbonilação com metanol, de um modo a que reaja com e converta certa quantidade ou todo o anidrido acético contido na mistura de ácido acético e de acetato de metila, alimentando a composição de reação resultante a um segundo reator de carbonilação e contactando a composição de reação para carbonilação.
