Abstract

Det beskrives en forbedring av metanolkarbonyleringsprosessen for fremstilling av eddiksyre. Nærmere bestemt beskrives en fremgangsmåte for å redusere dannelsen av alkyljodider og Cs-gkarboksylsyrer ved å fjerne permanganafreduserende forbindelser ("PRC-forbindelser) fra den lette fase av den kondenserte lettforbindelse-toppsfrøm, innbefattende (a) destillering av den lette fase for å danne en PRC-anriket toppsfrøm, og (b) eksfrahering av den fredje toppsfrøm med vann i minst to på hverandre følgende trinn og utskillelse fra denne av én eller flere vandige sfrømmer inneholdende PRC-forbindelser.
