Abstract

Fremgangsmåte for fremstilling av eddiksyre ved karbonylering av metanol og reaktive derivater av denne, i en reaksjonsblanding hvor det anvendes en rhodiumbasert katalysator og vannfattige betingelser. Det oppnås reaksjonshastigheter på minst 15 gmol/l/h. De høye reaksjonshastigheter skjer ved vannkonsentrasjoner på under 2,0 vekt%. Under bestemte betingelser holdes vannkonsentrasjonen i reaksjonsblandingen på ønsket nivå i reaksjonssystemet ved hjelp av minst ett prosesstrinn som innbefatter å tilsette en forbindelse som metylacetat, dimetyleter, eddiksyreanhydrid eller blandinger av disse. Prosesstrinnet med å tilsette disse komponenter til reaksjonsblandingen kan bli kombinert med andre prosesstrinn for å regulere vannkonsentrasjoner i reaksjonsblandinger for karbonylering av metanol.
