Abstract

El proceso comprende: (a) realizar la destilacion azeotropica en presencia de un agente separador orgánico seleccionado entre acetato de n-propilo yacetato de iso-butilo en una zona de destilacion para producir un componente de fase líquida quec omprende dicho ácido acético con un contenido de aguareducido en comparacion con el contenido de agua de la alimentacion y un componente de fase vapor que contiene el agente separador orgánico, agua yacetato de metilo; (b) pasar elcomponente de fase vapor a una zona de separacion, opcionalmente integral con dicha zona de destilacion, y separary recuperar una parte sustancial de acetato de metilo como un vapor mientras simultáneamente se reune agua, agenteseparador y una cant idad menor de acetatode metilo como una fase líquida; (c) separar la fase líquida resultante en 1) una fase orgánica que comprende principalmente agua con una cantidad menor deacetato de metilo; y d) retornar la fase orgánicaa la zona de destilac ion.
