1. Zastrzezenie patentowe Sposób otrzymywania wersenianu sodowo-zelazowego przez roztwarzanie elektrochemicz¬ ne zelaza metalicznego, znamienny tym, ze roztwarzanie przeprowadza sie w roztworze wodnym kwasu octowego do wyczerpania kwasu octowego, nastepnie otrzymany roztwór utlenia sie przepuszczajac przez roztwór powietrze lub tlen do zaniku wypadania z roztworu trudno rozpuszczalnego w wodzie zasadowego octanu zelazowego, który oddziela sie od roz¬ tworu, przemywa i wprowadza do zawiesiny wodnej wersenianu jednosodowego o temperaturze 70 - 90°C i utrzymuje sie w tej temperaturze ciagle mieszajac do zaniku reakcji komplekso¬ wania, a nastepnie schladza sie roztwór i poddaje krystalizacji, oddzielajac krysztaly wersenianu sodowo-zelazowego, natomiast odzyskany roztwór kwasu octowego stosuje sie do ponownej syntezy octanu zelazowego.
