(Ges. v. 15. 7. 51)(Ges. V. July 15, 51)
Als Spritzmittel im Obstbau haben sich in den letzten Jahren Präparate auf Basis von Dinitroorthokresol in größerem Umfange durchgesetzt. Diese Mittel werden mit einem Gehalt von 25% Dinitroorthokresol als Paste in den Handel gebracht. Reines Dinitroorthokresol läßt sich nicht in eine Emulsionsform überführen, sondern man verwendet die Natrium- oder Kaliumverbindung, obwohl das freie Dinitroorthokresol eine erheblich größere Wirksamkeit besitzt.In recent years, preparations based on dinitroorthocresol have proven to be a spray in fruit growing enforced on a larger scale. These funds are made with a content of 25% Dinitroorthocresol marketed as a paste. Pure dinitroorthocresol cannot be used converted into an emulsion form, but one uses the sodium or potassium compound, although the free dinitroorthocresol is considerably more potent.
Das Alkalisalz des Dinitroorthokresols ist in Alkohol und auch in Wasser ziemlich löslich und läßt sich daher leicht in Verbindung mit Seife oder Sulfitlauge in eine Paste überführen, die bei der vorgeschriebenen i°/oigen Anwendung eine klare Spritzbrühe ergibt.The alkali salt of dinitroorthocresol is quite soluble in alcohol and also in water can therefore easily be converted into a paste in conjunction with soap or sulphite liquor, which at the prescribed i ° / o application one results in a clear spray mixture.
Es wurde nun gefunden, daß sich Dinitroorthokresol sowohl in Mineral- wie auch in Teerölen bei einer Erwärmung auf etwa 6o°, also· unterhalb des Schmelzpunktes, glatt löst.It has now been found that dinitroorthocresol is found in both mineral and tar oils dissolves smoothly when heated to about 60 °, i.e. below the melting point.
In dieser Form läßt es sich mit Sulfitlauge emulgieren. Obwohl die Sulfitlauge zur Herstellung von Ölemulsionen nicht erwärmt werden darf, da sich sonst eine sogenannte umgekehrte Emulsion bildet, hat sich überraschenderweise gezeigt, daß bei dem langsamen Zugeben der warmen Dinitroorthokresollösung zu der kalten Sulfitlauge nicht, wie anzunehmen war, sich das Dinitroorthokresol durchIn this form it can be emulsified with sulphite liquor. Although the sulphite liquor for the production of oil emulsions must not be heated, because otherwise forms a so-called reverse emulsion, it has surprisingly been found that in the slowly adding the warm dinitroorthocresol solution to the cold sulphite liquor not how was assumed to be the dinitroorthocresol
die Abkühlung ausscheidet, sondern mit dem Öl und der Sulfitlauge eine völlig homogene Paste ohne Kristallbildung ergibt. Die mit dieser Paste angesetzte Spritzbrühe enthält das. Dinitroorthokresol in so feiner Verteilung, daß diese auch nach tagelangem Stehen keine Abscheidung zeigt. Der Gehalt an Dinitroorthokresol kann bis auf 50% gesteigert werden.the cooling separates, but a completely homogeneous paste with the oil and the sulphite liquor results in no crystal formation. The spray mixture prepared with this paste contains the dinitroorthocresol in such a fine distribution that it shows no separation even after standing for days. Of the Dinitroorthocresol content can be increased up to 50%.
An wen dung s bei spielApplication example
25 Teile Dinitroorthokresol werden in 35 Teilen Teeröl durch Erwärmen bis auf 6o° gelöst und mit 25 Teilen Sulfitlauge von 300 Be emulgiert. Nach der Zugabe werden noch 15 Teile Wasser zugesetzt. Man erhält eine Paste, die in üblicher Weise zum Ansetzen der Spritzbrühe benutzt wird und in der das Dinitroorthokresol eine erheblich größere Wirksamkeit besitzt als in seinen eingangs erwähnten Natrium- oder Kaliverbindungen. Diesen gegenüber besitzt die neue Mittelzusammenstellung noch den Vorzug, daß sie nicht wie jene verzinnte Transportbehälter benötigt, sondern in Pappe-, Preßspan-, Kunststoff- oder anderen Büchsen und Behältern in den Handel gebracht werden kann.25 parts dinitroorthocresol are dissolved in 35 parts of tar oil by heating up to 6o ° and emulsified with 25 parts of sulfite liquor 30 0 Be. After the addition, a further 15 parts of water are added. The result is a paste which is used in the usual way to prepare the spray liquor and in which the dinitroorthocresol is considerably more effective than its sodium or potassium compounds mentioned at the beginning. Compared to these, the new composition of funds still has the advantage that it does not need tinned transport containers like that, but can be marketed in cardboard, pressboard, plastic or other cans and containers.
