Description
Verfahren zur Herstellung von haltbaren Pyrethrumextrakt-Emulsionen. Die Verwendung von Pyrethrumextrakt als insektizides Mittel ist seit langem bekannt. Zu diesem Zweck wird Pyrethrumextrakt unter Verwendung von Seife in Einulsionsform übergeführt und die Emulsion unter Verdünnung mit Wasser verspritzt. Die seifenhaltigen Pyrethrumextrakt-Emulsionen haben aber den großen Nachteil, daß ihre Haltbarkeit eine geringe ist. Infolge der alkalischen Reaktion der Seife wird der ini Pyrethrumextrakt enthaltende w irksame Bestandteil, welcher ein Ester ist, einer teilweisen Spaltung unterworfen, und damit geht die Wirksamkeit des Produktes zurück. Somit war bisher die Handelsfähigkeit der Pyrethrumseifenlösungen gering.Process for the production of long-life pyrethrum extract emulsions. The use of pyrethrum extract as an insecticidal agent has long been known. For this purpose, pyrethrum extract is made in an emulsion form using soap transferred and sprayed the emulsion while diluting with water. The soapy ones Pyrethrum extract emulsions have the major disadvantage that their shelf life is a minor one. As a result of the alkaline reaction of the soap, the ini becomes pyrethrum extract active ingredient containing an ester, partial cleavage subject, and thus the effectiveness of the product decreases. So it was so far the merchantability of the pyrethrum soap solutions is low.
Es wurde nun gefunden, daß man haltb ' are wasserlösliche Eniulsioneil von Pyrethruniextrakt ohne Verwendung von Seifen in ausgezeichneter Weise unter Verwendtin g sulfierter, hochmolekularer Substanzen bzw. deren Salze, ferner unter Verwendung der Ligililisulfosäure und der Ligninsiure bzw. deren Salze oder unter Benutzung der Humiiisitire bzw. deren Salze oder ähnlicher Körper herstellen kann. Derartige Emulsionen zeichnen sich nicht nur durch ausgezeichnete Homogenität und große Verdfinnungsfähigkeit aus, sondern besitzen vor allein eine vorzügliche Haltbarkeit. Die insektizide Wirkung dieser Eintilsionen erleidet daher auch nach jahrelanger Aufbewahrung keine Beeinträchtigung. Mit Hilfe der oben angeführten Stoffe ist es möglich, nicht nur flüssige Präparate herzustellen, sondern man kann auch feste, pulverförmige Produkte erhalten, die einerseits in Wasser leicht aufgelöst und verspritzt werden können, welche aber auch anderseits nach der trockenen Bestäubungsmethode für Schädlingsbekämpfungszwecke benutzbar sind. Man kann selbstverständlich den Produkten noch andere Substanzen beimischen, und zwar solche von insektizidem oder fungizidem Charakter, oder auch indifferente Streckungsmittel, wodurch eine größere Verdünnung der Präparate hervorgerufen wird, oder auch Stoffe, welche die Haftfähigkeit und Ansteigbarkeit der Substanzen noch zu erhöhen vermögen.It has now been found that HALTB 'are water-soluble Eniulsioneil of Pyrethruniextrakt without the use of soap in excellent manner Verwendtin g of sulfonated, high molecular weight substances or their salts, and also using the Ligililisulfosäure and Ligninsiure or salts thereof, or using the Humiiisitire or their salts or similar bodies can produce. Such emulsions are not only characterized by excellent homogeneity and great thinnability, but above all have an excellent shelf life. The insecticidal effect of these infiltration is therefore not impaired even after years of storage. With the help of the substances listed above, it is not only possible to produce liquid preparations, but also solid, powdery products that can be easily dissolved and sprayed in water, but which can also be used for pest control purposes using the dry pollination method. Of course, you can add other substances to the products, namely those of an insecticidal or fungicidal character, or else indifferent extenders, which cause a greater dilution of the preparations, or substances which are able to increase the adhesiveness and ability of the substances to increase.
B e i s p i e 1 e 1. 35 kg Pyrethrumextrakt werden mit 2oo kg naplitholpecbstilfosaureni Natrium in der Kugelmühle zu einer gleichmäßigen Masse verarbeitet, dann mit etwa 300kg Wasser versetzt und so lange in der 'Mühle belassen, bis eine vollkommen honiogene el Masse entstanden ist. Selbstverständlich können die in der Beschreibung genannten Enlulsionsinittel in beliebiger Weise untereinander gemischt werden, um zu Präparaten mit besonderen Eigenschaften in bezug auf Haftfähigkeit, Farbe usw. zu gelangen.Eg p ie 1 e 1. 35 kg of pyrethrum extract are processed with 2oo kg of naplitholpecbstilfosaureni sodium in the ball mill to a uniform mass, then mixed with about 300 kg of water and left in the mill until a completely honiogenic el mass is formed. It goes without saying that the emulsifying agents mentioned in the description can be mixed with one another in any desired manner in order to obtain preparations with special properties in terms of adhesiveness, color, etc.
2. 35 kg Pyrethrumextrakt werden mit 2o kg benzylnaplitlialinsulfosaurein Natrium in der Kugelmühle zu einer gleichmäßigen Masse verarbeitet, dann nochmals mit 30kg der letztgenannten Substanz versetzt und so lange in der Mühle belassen, bis ein vollkommen homogenes Pulver entstanden ist. Das Pulver wird zweckmäßig mit einer indifferenten Substanz, wie Kaolin, Kieselgur usw., weiter gestreckt.2. 35 kg of pyrethrum extract are processed with 20 kg of benzylnaplitlialinsulfosaurein sodium in the ball mill to a uniform mass, then another 30 kg of the last-mentioned substance are added and left in the mill until a completely homogeneous powder is obtained. The powder is expediently further stretched with an inert substance such as kaolin, kieselguhr, etc.
