Abstract

Procedimiento para separar parcialmente el agua contenida en mezcla de gases que se forman en la obtención de acetato de vinilo mediante la reacción de atileno con ácido acético y oxigeno en catalizadores en la fase gaseosa, y uqe como componente principales contienen ácido acético, acetato de vinilo, agua, anhídrido carbónico y etileno, caracterizado porque la mezcla de gases salientes de la zona de la reacción se introduce en una columna de destilación; porque la mezcla saliente en forma gaseosas por la cabeza de la columna de destilación se enfría hasta -20 a +50º C, y porque del producto condensado que con ello se forma y que se divide en dos fases, se retira la fase gaseosa, mientras que la fase orgánica se devuelve total o parcialmente a la columna, extrayéndose del fondo de la columna una mezcla consistente sustancialmente en acetato de vinilo, ácido acético y agua.
