Abstract

Det beskrives en forbedring av metanolkarbonyleringsprosessen for fremstilling av eddiksyre. Nærmere bestemt beskrives en fremgangsmåte for å fjerne permanganafreduserende forbindelser ("PRC- forbindelser") fra den kondenserte toppsfrøm av lette forbindelser, innbefattende (a) destillasjon av i det minste en andel av de kondenserte lette forbindelser i toppsfrømmen for å danne en PRC-anriket andre toppsfrøm, (b) eksfrahering av den andre toppsfrøm med vann og utskillelse fra denne av en vandig sfrøm inneholdende PRC-forbindelser, og (c) tilbakeføring av i det minste en andel av den ekstraherte andre toppsfrøm til den andre destillasjonskolonne.
