Description

Verfahren zur Entwässerung und Zersetzung von Eisenvitriol Durch das Hauptpatent 529 384 ist ein Verfahren zur Entwässerung und zur Zersetzung von Eisenvitriol geschützt, gemäß dem die Entwässerung. und Zersetzung in Gegenwart von Zersetzungsprodukten eines Eisensalzes vorgenommen wird.Process for the dehydration and decomposition of iron vitriol By the Main patent 529 384 is a process for the dehydration and decomposition of iron vitriol protected, according to which the drainage. and decomposition in the presence of decomposition products an iron salt is made.

Es wurde gefunden, daß die Menge der zuzusetzenden Zersetzungsprodukte dadurch verringert werden kann, daß man einen Teil derselben durch ganz oder teilweise entwässerten Eisenvitriol ersetzt. Beispiel Ferrosulfat mit 7 aq wird mit 5 bis io 0o Eisenoxyd (das bei der Zersetzung erhalten wurde) und -mit io bis 30 % wasserfreiem Ferrosulfat (das bei der Entwässerung erhalten wurde) vermischt und nach dem Verfahren des- Patents 529 384 einem Entwässerungs-und Zersetzungsprozeß unterworfen.It was found that the amount of the decomposition products to be added can be reduced in that one part of it by wholly or partially replaced dehydrated iron vitriol. Example ferrous sulfate with 7 aq is with 5 to io 0o iron oxide (which was obtained during the decomposition) and -with io to 30% anhydrous Ferrous sulfate (obtained from dehydration) mixed and processed des-Patent 529,384 subjected to a dehydration and decomposition process.
