Description

Verfahren zur Herstellung von Pyrethrumextrakt-Emulsionen Für die Einulgierung von Alkaloiden, z. B. Derrisextrakt usw., kann jedes beliebige Emulsionsmittel Verwendung fin#den. Für empfindliche Substanzen, Z. B. Pvrethrumextrakt, dessen wirksame Bestanäteile aus gegen chemische Einflüsse sehr empfindlichen Estern bestehen, ist die Zahl dagegen sehr beschränkt.Process for the preparation of pyrethrum extract emulsions For the emulsification of alkaloids, e.g. B. derrise extract, etc., any emulsifying agent can be used. For sensitive substances, e.g. pvrethrum extract, the effective components of which consist of esters that are very sensitive to chemical influences, the number is very limited.

lii weiterer Ausarbeitung des Gegenstandes des Patents 431 699 wurde nun gefunden, daß man wertvolleEmulsionen vonPvrethrumextrakt von sehr guter Haltbarkeit dadurch herstellen kann, daß man als Einulgierungsz# mittel die Sulfierungsprodukte von Geinischen aromatischer Substanzen verwendet ' wie sie in einer Reihe billiger technischer Produkte vorliegen, so beispielsweise ini Edeleanuöl, welches bei der Petroleumreinigung nach dein Edeleanuverfahren gewonnen wird, oder im Solar51, einem Abfallöl bei der Bratinkohlenschwelerei. Mit Hilfe der genannten Stoffe ist es möglich, sowohl flüssige als auch feste pulverförmige Produkte herzustellen.lii further elaboration of the subject matter of the patent 431 699 has now been found that valuable emulsions can produce very good durability by vonPvrethrumextrakt that as Einulgierungsz # medium the sulfation of Geinischen aromatic substances used 'as they are present in a number less technical products, so for example ini Edeleanu oil, which is obtained from petroleum cleaning according to the Edeleanu process, or in Solar51, a waste oil from the roasting charcoal mill. With the help of the substances mentioned, it is possible to produce both liquid and solid powdery products.

Für die Anwendung werden dieselben entweder in Wasser aufgelöst und verspritzt Z, oder können als Stäubemittel in trockener Form auf die zu schützenden Pflanzenteile aufgebracht werden. NMan kann den Produkten andere Substanzen beimischen, und zwar solche von insektizidem und fungizidem Charakter, oder auch indifferente StreckLingsmittel oder solche Stoffe, welche die Haftfähigkeit und Anteigbarkeit der Produkte noch erhöhen.For use, the same are either dissolved in water and sprayed Z, or can be applied as a dust in dry form to the parts of the plant to be protected. NMan can add other substances to the products, namely those of an insecticidal and fungicidal character, or also indifferent extenders or substances which increase the adhesiveness and pourability of the products.

B e i s p i e 1 e 1. 9,5 Teile Pyrethrumextrakt werden allniMilich mit 66feilen stilfoniertem Edeleannextrakt versetzt und verrieben, bis eine gleichmäßige Emulsion entstanden ist. Mall verdünnt dann mit 24,5 Teilen Wasser.Eg p ie 1 e 1. 9.5 parts of pyrethrum extract are mixed with fine-grained Edeleannextrakt and rubbed in until a uniform emulsion is formed. Mall then diluted with 24.5 parts of water.

2. 9,5 Teile Pyrethrumextrakt werden mit 5o Teilen Natronsalz des sulfonierten Edeleanuextraktes und 40,5 Teilen Kieselgur so lange in geeigneter Weise durchgearbeitet, bis eine vollkommen hornogeneMischung entstanden ist. 2. 9.5 parts of pyrethrum extract are worked through in a suitable manner with 50 parts of the sodium salt of the sulfonated Edeleanu extract and 40.5 parts of kieselguhr until a completely hornogenic mixture is obtained.
