Abstract

En el presente documento se proporciona un proceso para la producción y purificación de ácido acético. En particular, la presente divulgación se refiere a procesos mejorados para producir y purificar ácido acético mediante la carbonilación de metanol en presencia de un catalizador de carbonilación metálico del Grupo VIII. El proceso de producción y purificación de ácido acético descrito en el presente documento controla la formación y la composición en masa de las impurezas de acetal, tales como 1,1-dimetoxietano.
