Patentanspruch:Claim: Verfahren zur Reinigung manganhaltiger Essigsäure, wie sie vorzugsweise bei der Oxydation des Acetaldehyde durch Sauerstoff mittels Manganverbindungen erhalten wird, dadurch gekennzeichnet, daß die Rohessigsäure mit Oxalsäure bzw. Oxalaten, vorzugsweise in der Hitze, behandelt wird und das entstandene Manganoxalat von der Säure abgetrennt wird, worauf noch eine weitere Reinigung durch das an sich bekannte Ausfrieren der Essigsäure erfolgen kann.Process for purifying acetic acid containing manganese, as is preferred at the oxidation of acetaldehyde by oxygen by means of manganese compounds is, characterized in that the crude acetic acid is treated with oxalic acid or oxalates, preferably in the heat and the resulting manganese oxalate is separated from the acid, whereupon a further purification is carried out the per se known freezing of acetic acid can take place. *) Von dem Patentsucher sind als die Erfinder angegeben worden:*) The patent seeker indicated the following as the inventors: Dr. Rudolf Meingast und Dr. Martin Mugdan in München.Dr. Rudolf Meingast and Dr. Martin Mugdan in Munich.
