Abstract

Fremgangsmåte for fremstilling av en eddiksyreprosesstrom omfattende mindre enn 400 ppm propionsyre og mindre enn 1500 ppm vann, innbefattende trinnene: (a) tilførsel av metanol og/eller et reakiivt derivat derav og karbonmonoksyd lil en karbonyleringsreaktor hvori det under prosessforlopet opprettholdes en flytende reaksjonssammensetning omfattende: (i) en iridiumkarbonyleringskatalysator; (ii) metyliodid-kokatalysator; (iii) eventuelt en eller flere promotorer valgt fra gruppen bestående av ruthenium, osmium, rhenium, cadmium, kvikksølv, sink, gallium, indium og wolfram; (iv) en endelig mengde vann ved en konsentrasjon på mindre enn ca 8 vekt-%; (v) metylacetat; (vi) eddiksyre; og (a) propionsyrebiprodukt og dets forløpere, (b) fjerning av flytende reaksjonssammensetning fra karbonyleringsreaktoren og innføring av i minst n del av den fjernede flytende reaksjonssammensetningen, med eller uten tilføring av varme, i en trykkavlastningssone for dannelse av en dampfraksjon omfattende vann, eddiksyreprodukt, propionsyrebiprodukt, metylacetat, metyliodid og propionsyreforløpere, og en væskefraksjon omfattende ikke-flyktig iridiumkatalysator, ikke-flyktig eventuell promotor eller promotorer, eddiksyre og vann; (c) resirkulering av væskefraksjonen fra trykkavlastningssonen til karbonyleringsreaktoren; (d) innføring av dampfraksjonen fra trykkavlastningssonen i en første destillasjonssone; (e) fjerning fra den første destillasjonssonen ved et punkt over innføringspunktet for trykkavlastningssone-dampfraksjonen av en resirkuleringsstrøm av lettkokende dcstillasjonsbestanddeler omfattende vann, metylacetat, metyliodid, eddiksyre og propionsyreforløpere hvilken strøm resirkuleres helt eller delvis til karbonyleringsreaktoren, og (O fjerning fra den første destillasjonssonen ved et punkt under innforingspunktet for trykkavlastningssone-dampfraksjonen, av en prosesstrøm omfattende eddiksyreprodukt, propionsyrebiprodukt, og mindre enn 1500 ppm vann og , (g) dersom prosesstrømmen fjernet i trinn O omfatter mer enn 400 ppm propionsyre, innføring av nevnte strøm i en annen destillasjonskolonne, fjerning fra et punkt under innføringspunktet for strømmen fra f) av propionsyrebiprodukt og fra et punkt over innforingspunktet for strømmen fra O av en eddiksyreprosesstrøm inneholdende mindre enn 400 ppm propionsyre og mindre enn 1500
