Description

Verfahren zur Herstellung eines schwefelsäurehaltigen pulverförmigen Ackerunkraut-Vernichtungsmittels Die Anwendung von Schwefelsäure als Spritzmittel zur Unkrautvernichtung ist bekannt, desgleichen die Verwendung von gemahlenem Eisenvitriol als Streumittel. In dem Patent 259 767 ist weiter ein breifürmig f S e Unkrautvernichtungsmittel aus Eisenvitriol und Schwefelsäure beschrieben. Nachstehend wird ein Verfahren zur Herstellung eines pulverförmigen Streumittels gegen Ackerunkräuter beschrieben, das Eisenvitriol und freie Schwefelsäure enthält.Process for the production of a powdered arable weed killing agent containing sulfuric acid The use of sulfuric acid as a spray for weed killing is known, as is the use of ground iron vitriol as a spreading agent. In the patent 259 767 is described a breifürmig f S e herbicides from ferrous sulphate and sulfuric acid. The following describes a process for the production of a powdered sprinkling agent against arable weeds, which contains iron vitriol and free sulfuric acid.

Man geht vom sogenannten Hochofen- oder Gichtstaub aus, der sich in Hochofenwerken als unbrauchbares Haldenmaterial ansammelt. Dieser Gichtstaub enthält neben 3o bis 5o °/o Eisen, das teilweise metallisch, teilweise in Ferro- und Ferriform vorhanden ist, noch das als Stimulans bekannte Mangan und Phosphorsäure.One assumes the so-called blast furnace or blast furnace dust, which is in Blast furnace plants accumulates as unusable dump material. This contains gout dust in addition to 3o to 5o% iron, which is partly metallic, partly in ferrous and ferrous form present, manganese and phosphoric acid, which are known as stimulants.

Bei der Umwandlung des Eisens in Sulfat wurde die überraschende Beobachtung gemacht, daß der Gichtstaub große Mengen Schwefelsäure zu binden vermag und schließlich, ohne daß er getrocknet zu werden braucht, in ein leicht zerreibbares, nicht hygroskopisches Pulver zerfällt, das sich vorzüglich streuen läßt.The surprising observation was made when the iron was converted into sulphate made that the gout dust is able to bind large quantities of sulfuric acid and finally, into an easily friable, non-hygroscopic one without needing to be dried Powder disintegrates and is easy to sprinkle.

Beispiel ioo kg Schwefelsäure von. 66° Be werden mit i 5o kg Gichtstaub gemischt. Nach dem Erkalten erhält man ein trockenes Pulver mit einem Gehalt von 28,6 % Fe S O, # 7 H20 und 31,00/, H2 S 04, das dann als Streumittel gegen Hederich usw. benutzt wird.Example 100 kg of sulfuric acid from. 66 ° Be are mixed with 15o kg of gout dust. After cooling, a dry powder with a content of 28.6 % Fe SO, # 7 H20 and 31.00 /, H2 S 04 is obtained, which is then used as a scattering agent against Hederich etc.
