Description

Verfahren zur Herstellung eines Schädlingsbekämpfungsmittels Gegenstand vorliegender Erfindung bildet ein Verfahren zur Herstellung eines Schädlingsbekämpfungsmittels, das dadurch gekennzeichnet ist, daß die Kupfer- oder Bleisalze der Ichthyolsulfosäure durch Zusatzeines Alkalisalzes einer Oxysäure und eines Alkalis "in wasserlösliche Form übergeführt werden.Method of making a pesticide article The present invention provides a process for the preparation of a pesticide, which is characterized in that the copper or lead salts of ichthyolsulfonic acid by adding an alkali salt of an oxyacid and an alkali "into water-soluble Form to be transferred.

Es ist bereits bekannt, Ichthyolsulfosäuren zusammen mit Glycerin und Seife zu einer Paste zu verrühren. Es handelt sich dabei aber um Stoffe, die an und für sich schon wasserlöslich sind.It is already known to use ichthyol sulfonic acids together with glycerin and soap to stir into a paste. But these are substances that are in and of themselves water-soluble.

Es ist auch weiter bekannt, Bariuinsalze von Sulfosäuren hochmolekularer Stoffe, insbesondere von Harz- oder Pechcharakter, in Mischung mit anderen Mitteln von fungieider und insekticider Wirkung, wie einer Schwefelkalkbrühe, als Schädlingsbekämpfungsmittel zu verwenden.It is also known to use barium salts of sulfonic acids of high molecular weight Substances, especially those of resin or pitch, mixed with other agents has a fungicidal and insecticidal effect, such as a broth of lime sulfur, as a pesticide to use.

Demgegenüber handelt es sich bei der Erfindung darum, die unlöslichen Kupfer- oder Bleisalze der Ichthyolsulfosäure löslich zu machen, und zwar durch Alkalisaize von Oxysäuren.In contrast, the invention is about the insoluble To make copper or lead salts of ichthyol sulfonic acid soluble by Alkali values of oxyacids.

An Stelle der Ichthyolsulfosäuren können auch andere in ähnlicher Weise durch Sulfonierung von Schwefel enthaltenden Mineralölen erhaltene Sulfosäuren verwendet werden. Man erhält so in wasserlöslicher Form Schädlingsbekämpfungsmittel, die einerseits die fungiciden und insekticiden Wirkungen der Ichthyolsulfosäure und andererseits die antiparasitären Wirkungen der Kupfer- oder Bleisalze haben.Instead of ichthyol sulfonic acids, others can be used in a similar manner Sulfonic acids obtained by sulfonating sulfur-containing mineral oils be used. This gives pesticides in water-soluble form, on the one hand the fungicidal and insecticidal effects of ichthyolsulfonic acid and on the other hand have the anti-parasitic effects of the copper or lead salts.

Als Salze von Oxysäuren können beispielsweise die Alkalisalze der Citronensäure oder Weinsäure verwendet werden.As salts of oxy acids, for example, the alkali salts of Citric acid or tartaric acid can be used.

Man muß weiter dafür Sorge tragen, daB das Endprodukt schwach alkalisch reagiert, was durch Zusatz von Alkali oder Ammoniak geschehen kann. Die Mengenverhältnisse der verschiedenen Stoffe müssen dabei folgende sein: Die Menge des zu verwendenden Kupfer-oder Bleisalzes entspricht der Menge, die höchstens nötig ist, um das entsprechende Sulfonat zu bilden.Care must also be taken to ensure that the end product is weakly alkaline reacts, which can happen by adding alkali or ammonia. The proportions of the different substances must be as follows: The amount of the to be used Copper or lead salt corresponds to the amount that is at most necessary to make the corresponding To form sulfonate.

Die Oxysäuresalze werden in der (geringsten) Menge zugesetzt, die zur Lösung der unlöslichen Sulfonate nötig ist. Bei der Verwendung des Kupfersalzes z. B. ist das Verhältnis des Kupfers zur Oxysäure dasselbe wie das Verhältnis einer doppelt normalen Lösung von Kupfersulfat zu einer o,9 normalen Lösung der Oxysäure. Ausführungsbeispiel Zu ioo kg Ichthyolsulfosäure gibt man 5o kg fein verteiltes Kupfersulfat, 25 kg Seignettesalz und 40 1 Ammoniak hinzu. _ Man rührt so lange, bis die Mischung homogen ist und gibt dann Natronlauge in 3o%iger Lösung hinzu, bis die Reaktion schwach alkalisch ist.The oxy acid salts are added in the (smallest) amount that is necessary to dissolve the insoluble sulfonates. When using the copper salt z. B. the ratio of copper to oxyacid is the same as the ratio of one double normal solution of copper sulfate to a 0.9 normal solution of oxyacid. Embodiment 50 kg of finely divided ichthyolsulfonic acid are added to 100 kg of ichthyolsulfonic acid Copper sulfate, 25 kg of Seignette salt and 40 liters of ammonia are added. _ One stirs so long until the mixture is homogeneous and then add sodium hydroxide solution 3o% Add solution until the reaction is weakly alkaline.
