Abstract

Metodo per la rimozione dei contaminanti acidi e salini dalla fase condensata dell'effluente di reazione in un processo per la sintesi di dimetilcarbonato, che consiste nel sottoporre detta fase a vaporizzazione parziale.Dalla suddetta vaporizzazione parziale si ottiene una corrente principale vaporizzata sostanzialmente priva di detti contaminanti ed una corrente secondaria liquida contenente gli stessi.
