Description

Schädlingsbekämpfungsmittel. Es wurde gefunden, daß sich Tier- und Pflanzenschädlinge jeder Art in ganz hervorragender Weise vertilgen lassen mit aromatischen Sulfosäuren bzw. ihren Salzen, deren 1,ösungen den Charakter von'Seifenlösungen, insbesondereeine hohe Netzfähigkeit, besitzen. Als solche aromatische Sulfosäuren seien an erster Stelle die ' Sulfosäuren propyl- bzw. isopropylgruppenhaltiger Verbindungen, z.'B. isopropy-lierte Benzol- oder Naphthalinsulfosäuren, oder auch solche genannt, die den Butylrest, z. B. das Radikal CHS - C H - C2H5, enthalten. Diese Verbindungen werden zweckmäßig in Form ihrer neutralen Salze, auch solcher von Schwermetallen, verwendet. Es genügt im allgemeinen schon eine Lösung von 1 ' /_, oder weniger Prozent, doch lassen sich ohne Schädigung von Pflanzen und Tieren auch stärker konzentrierte Lösungen anwenden. Ferner können auch gleichzeitig andere, für die Schädlingsbekämpfung geeignete Substanzen zugesetzt werden. Gemische, die in Wasser unlösliche, höher molekulare Alkohole oder Keton#e neben Alkalisalz#en der Tetrahydronaphthalinsulf-osäuren oder ihren Abkömmlingen enthalten, werden hier ausgenommen. Beispiel i. 3 8 4 Teile Naphthalin werden mit 4 5 o Teilen Schwefelsäure von 66' B6 in ß-Naphthalinsulfosäure übergeführt. Nach dem Abkühlen auf i2o' läßt man unterRühren einGemisch von 38o Teilen Isopropylalkohol und 265 4 Schwefelsäure 66' B6 zufaufen. Nach mehrstündigem Rühren bei dieser Temperaturläßt man erkalten, hebt die obere Schicht ab, kalkt und führt das Kalksalz in das NatriunÄsalz; über. Die Lösung wird z. B. auf 1/2 Prozent verdünnt und kann dann ohne weiteres in der üblichen Weise verwendet werden. Beispiel 2. Trockener, venhlierter oder präzipitierter Schwefel wird mit etwa 5"Prozent seines Gewichts von dem in Beispiel i erwähnten isopropylierten, naphthalinsulfosauren Natrium gut gemischt. Das Produkt benetzt sich beim Eintragen in -Wasser sofort, ebenso werden Pflanzenteile, die mit einer so hergestellten wäßrigen Schwefelsuspension bespritzt werden, vorzüglich benetzt.Pesticides. It has been found that animal and plant pests of all kinds can be exterminated in a very excellent manner with aromatic sulfonic acids or their salts, the solutions of which have the character of soap solutions, in particular high wetting properties. As such aromatic sulfonic acids in the first place the "sulfonic acids are propyl or isopropylgruppenhaltiger compounds z.'B. isopropylated benzene or naphthalenesulfonic acids, or also called those which contain the butyl radical, e.g. B. contain the radical CHS - C H - C2H5. These compounds are expediently used in the form of their neutral salts, including those of heavy metals. It is generally sufficient already a solution of 1 '/ _, or less percent, but can be no damage to plants and animals and more concentrated solutions apply. Furthermore, other substances suitable for pest control can also be added at the same time. Mixtures which contain water-insoluble, higher molecular weight alcohols or ketones in addition to alkali salts of tetrahydronaphthalenesulfonic acids or their derivatives are excluded here. Example i. 3 8 4 parts of naphthalene converted with 4 o 5 parts of sulfuric acid of 66 'B6 in beta-naphthalenesulfonic acid. After cooling to 120 ', a mixture of 38o parts of isopropyl alcohol and 265 4 of sulfuric acid 66' B6 is added with stirring. After stirring for several hours at this temperature, the mixture is allowed to cool, the upper layer is lifted off, limed and the lime salt is added to the sodium salt; above. The solution is z. B. diluted to 1/2 percent and can then readily be used in the usual manner. Example 2. Dry, powdered or precipitated sulfur is mixed well with about 5 "percent of its weight of the isopropylated, naphthalenesulfonic acid sodium mentioned in Example I. The product wets itself immediately when it is put into water aqueous sulfur suspension are sprayed, excellent wetted.

Ebenso kann man kolloidale Schwefellösungen mit aromatischen Sulfosäuren, deren Salzen oder ihren Lösungen, die den Charakter von S#eifenlösungen besitzen, versetzen.You can also use colloidal sulfur solutions with aromatic sulfonic acids, their salts or their solutions, which have the character of soap solutions, offset.
