Description
Lagerbeständiges Ackerunkrautvemichtungsmittel Du,rch Patent 619237 ist ein Unkrautvernichtungsmittel ges-chützt, das aus einem Gemisch von wasserarmem Kupfersulfat mit den aus Chlorzink und Chlorammonium entstandenen Doppelsalzen besteht" gegebenenfalls mit einem überscIluß an Chlorzink. Das Zinkchlorid steigert dabei die an sich bekannte Wirkung des Kupferions. Solche Gemische haben volle. Wirkung auf Ackerunkraut trotz eines wesentlich geringeren Gehalts an Kupfer im Vergleich mit Kupfersujfat.Shelf-life arable weed killer Du, rch patent 619237 is a weed killer protected from a mixture of water-poor Copper sulphate with the double salts formed from chlorine zinc and chlorine ammonium " possibly with an excess of zinc chloride. The zinc chloride increases the known effect of the copper ion. Such mixtures have full. effect on field weeds despite a much lower content of copper in comparison with copper sufate.
Es ist somit gegenüber dem Kupferstill'-#i.t eine wesentlich erhöhte Wirk-samkeit erzielt worden. Die beschriebenen Produ,1,-te sind lagerbeständig. Der Gehalt des Kupfersulfats an Wasser liegt dabei unter iooilo.It is therefore a considerably higher level than the copper style Effectiveness has been achieved. The products described are storable. The water content of the copper sulphate is less than 100,000.
Es wurde nun gefunden, daß man mit gutem Erfolg an Stelle des Kupfersulfats auch wasserarm#es Kupferchlorid einzeln für sich oder im Gemisch mit Kupfersulfat verwenden kann, wobei die oben für das Gemisch gemäß Hauptpatent beschriebene steigernde Wirkung des Zinkchlorids auf das Kupferion gleichfalls eintritt.It has now been found that # also low in water with good results in place of copper sulfate can use it alone or in a mixture with copper sulfate, copper chloride alone, with the top of the mixture according to the main patent described increasing effect occurs the zinc chloride on the copper also.
Es läßt sich also das Kupfersulfat ganz oder teilweise durch Kupferchlorid ersetzen. Zweckmäßig wird eine der -zu ersetzenden Menge des Kupfersulfats äquivalente Menge von Kt#pferchlorid verwendet. Das Kupfer-.chlorid wird wie dm Kuipfersulfat gemäß dem Hauptpatent praktiscli wasserfrei oder teilweise (bis auf einen Höchstwassergehalt von io%) entwässert verwendet.So the copper sulfate can be completely or partially replaced by copper chloride substitute. Appropriately, an amount of copper sulfate to be replaced is equivalent Amount of Kt # chloride used. The copper chloride is like copper sulfate according to the main patent practically anhydrous or partially (up to a maximum water content of io%) dehydrated.
Beispielsweise erhält man lagerfähige Unkrautvernichtungsmittel, wenn man 5o Teile gepulverte Chlorzinksalmiakschmelze in gleicher Weise herstellt, wie im Beispiel des Patents 619237 angegeben, mit 5o Teilen praktisch wasserfreiem Kupferchlorid oder 5o Teile gepulverte Chlorzinksalmiaksichmelze mit 25 Teilen praktisch wasserfreiem Kupfersulfat und 25 Teilen praktisch wasserfreiem. Kupferchlorid vermischt.For example, storable weedkillers are obtained if 50 parts of powdered chlorzinc almiac melt are prepared in the same way as indicated in the example of patent 619237, with 50 parts of practically anhydrous copper chloride or 50 parts of powdered chlorzinc almiac melt with 25 parts of practically anhydrous copper sulfate and 25 parts of practically anhydrous. Copper chloride mixed.
Den Mischungen können je nach Bedarf noch i bis 3 Teile Natriumdisulfat zugesetzt werden. Depending on requirements, 1 to 3 parts of sodium disulfate can also be added to the mixtures.
Diese neuen Unkrautvertilgungsmittel be- sitzen gegenüber den bekannten Kupfersalzen die gleichen Vorteile, wie sie in dem Hauptpatent an Hand eines Beispieles für die dort genannten Mittel zahlenmäßig na-chgewiesen worden sind. Gegenüber den Mitteln des Hauptpatents haben sie den weiteren Vorteil der rascheren Wirksamkeit.These new herbicides sit loading compared to the known copper salts the same advantages as those in the main patent of an example for the mentioned there means numerically na-chgewiesen. Compared to the means of the main patent, they have the further advantage of faster effectiveness.
