Description

Schönen von Trauben-, Obst- und Beerenweinen und -mosten Durch das Patent 679 646 wird ein Verfahren zum Schönen von Trauben-, Obst- und Beerenweinen und -mosten geschützt, das gekennzeichnet ist durch die Verwendung solcher amorpher Eisenoxyde, die durch Erhitzen von Eisenhydroxyden bis zur weitgehenden Entwässerung hergestellt worden sind.Beautiful of grape, fruit and berry wines and musts Patent 679,646 describes a process for enhancing grape, fruit and berry wines and must protected, which is characterized by the use of such amorphous Iron oxides, which by heating iron hydroxides to extensive dehydration have been manufactured.

Es wurde nun* gefunden, daß sich das Arsen und Blei aus den genannten Getränken in besonders vorteilhafter Weise auch dadurch entfernen lassen, daß dieselben mit kristallinen aktiven Eisenoxyden behandelt werden, die in bekannter Weise durch vorsichtige Entwässerung aus ausgeprägt kristallinen, natürlichen oder künstlichen Eisenoxydhydraten hergestellt sind.It has now been found that make the arsenic and lead from said beverages in a particularly advantageous way, thereby removing that are the same treated with crystalline active iron oxides prepared the crystalline in a known manner by the careful dewatering of pronounced natural or artificial Eisenoxydhydraten are.

Geeignete künstliche Eisenoxydhydrate können beispielsweise erhalten werden, wenn man ihre Bildung aus Eisen oder Eisenverbindungen in an sich bekannter Weise so leitet, daß durch die an sich bekannten Maßnahmen zur Herabsetzung der Häufungsgeschwindigkeit und Erhöhung der Ordnungsgeschwindigkeit die Entstehung kristalliner Verbindungen bevorzugt wird. Das so erhaltene Material zeigt infolge seiner kristallinen Struktur keine Neigung, beim Trocknen zu harten Scheiben zusammenzuschrumpfen. Es läßt sich infolgedessen vermittels vorsichtiger weitgehendere Entwässerung, z. B. durch Erhitzen in einem inerten Gasstrom oder im Vakuum zwischen 2oo° und 4oo°, in ein Oxyd überführen, dessen besonderer Vorzug darin liegt, daß es sich mühelos äußerst fein dispergieren läßt. In dieser Form entfaltet es eine bedeutende Oberflächenaktivität, die selektiven Absorptionscharakter gegenüber Arsenverbindungen zeigt. Als vorteilhaft hat es sich gezeigt, wenn die zur Verwendung gelangenden Eisenoxyde einen Gehalt -an Aluminiumoxyd aufweisen.Suitable artificial iron oxide hydrates can be obtained, for example if one considers their formation from iron or iron compounds in per se Way so that by the known measures to reduce the Accumulation speed and increase in the rate of order the emergence crystalline compounds is preferred. The material thus obtained shows as a result its crystalline structure has no tendency to shrink into hard disks when drying. It can consequently by means of more careful more extensive drainage, z. B. by heating in an inert gas stream or in a vacuum between 2oo ° and 4oo °, converted into an oxide, the particular advantage of which is that it can be easily removed Can be dispersed extremely finely. In this form it develops a significant surface activity, which shows selective absorption character towards arsenic compounds. As beneficial it has been shown when the iron oxides used have a content -an aluminum oxide.

Durch die Behandlung von Most oder Wein mit solchen Eisenoxyden wird eine praktisch vollständige Entfernung des Arsens und des Bleis erreicht, ohne daß der Geschmack des Weines durch diese Behandlung wesentlich leidet und ohne daß praktisch störende Mengen Eisen hierbei in Lösung gehen.By treating must or wine with such iron oxides achieved a practically complete removal of arsenic and lead without the taste of the wine suffers considerably as a result of this treatment and without being practical disruptive amounts of iron go into solution here.

Beispiel r In einen arsenhaltigen Wein wird ein auf die beschriebene Weise hergestelltes kristallines Eisenoxyd in einer Menge von Zoo g/hl eingetragen. Im Verlauf von 8 Tagen wird durch mehrfaches Umrühren für möglichst gute Verteilung gesorgt. Alsdann wird der Wein abgestochen und durch ein Anschwemmfilter filtriert, In Geschmack und Farbe ist der Wein nicht wesentlich verändert. Eisen ist nicht in Lösung gegangen. Beispiel z In einem bleihaltigen Apfelsaft werden 5oo g eines auf die beschriebene Weise hergestellten Eisenoxyds pro Hektoliter suspendiert. Bei täglich zweimaligem Aufrühren bleibt der Saft 6 Tage stehen. Darauf wird von Eisenoxyd abfiltriert. Die analytische Untersuchung ergibt nur noch geringe Spuren von Blei, die nicht mehr gesundheitsschädlich sind.Example r In a wine containing arsenic one is described on the Wise produced crystalline iron oxide entered in an amount of zoo g / hl. Over the course of 8 days, stir several times for the best possible distribution taken care of. Then the wine is tapped and filtered through a precoat filter, The taste and color of the wine have not changed significantly. Iron is not gone into solution. Example z Be in a leaded apple juice 500 g of an iron oxide prepared in the manner described per hectolitre suspended. If stirred twice a day, the juice will stand for 6 days. This is followed by Iron oxide filtered off. The analytical examination shows only small traces of lead, which are no longer harmful to health.
