Abstract

Den foreliggende oppfinnelse er rettet mot en fremgangsmåte for konsentrasjon av vandig hydrogenperoksid omfattende diskontinuerlig krystallisasjon. Ifølge foreliggende oppfinnelse er en kjøleflate anordnet i et krystallisasjonskar og fuktes først med hydrogenperoksid, avkjøles ved en høy avkjølingshastighet, ved hvilken frøkrystaller dannes. Avkjølingshastigheten er på minst 1 K/s, fortrinnsvis fra 10 til 30 K/s. Når karet er blitt fylt med HOutgangsmateriale, vil sist nevnte krystallisere startende fra frøkrystallene og danne et krystallsjikt. Når moder luten med lav HOkonsentrasjon er blitt fjernet følger en svettingsoperasjon med en langsom temperaturøkning, som et resultat derav øker HOkonsentrasjonen i krystallsjiktet ytterligere.
