description

Die Verteilung des Kieselsaure-Brenzcatechin-Komplexes zwischen wasrigen Losungen und verschiedenen organischen Losungsmitteln wurde in Gegenwart von organischen Basen untersucht. Dabei wurden der pH-Wert und die Konzentrationen an Brenzcatechin und an organischer Base variiert. Kieselsaure kann bei pH 9,2–9,3 mit Nitrobenzol praktisch vollstandig ausgeschuttelt werden, wenn die Brenzcatechin-Konzentration in der Wasserschicht 0,5 M und die Diphenylguanidin-Konzentration in der organischen Phase mindestens 0,25 M ist.
