Description
Verfahren zur Herstellung von wässrigen Lösungen von Schwefel in elementarer Form. Es ist bekannt, elementaren Schwefel mit hydrierten aromatischen Aminen, wie z. B. Cyclohexylamin, Piperidin, Nikotin usw. in eine konzentrierte Lösung zu bringen, die beim Eintragen in Wasser den Schwefel in kolloidaler Form abscheidet.
Diese wässrigen Schwefellösungen haben jedoch den Nachteil, dass sie den Schwefel nur in kolloidaler Form enthalten und nur eine begrenzte Haltbarkeit aufweisen.
Es wurde nun gefunden, dass man die mit den hydrierten aromatischen Aminen erhaltenen konzentrierten Schwefellösungen dadurch in für den praktischen Gebrauch (z. B. Kosmetik, Schädlingsbekämpfung usw.) verwendbare verdünnte, wässrige echte Schwe fellösungen von unbegrenzter Haltbarkeit über führen kann, dass man die erhaltenen kon zentrierten Lösungen des Schwefels mit wäss- rigen Lösungen vermischt, die mindestens einen Lösungsvermittler enthalten. Als solche Lösungsvermittler sind z.
B. die Cyclohexyl- amin-Oleinseifen, die Alkalisalze, insbeson- dere die Kaliseifen der Ölsäure, Fettalkohol- sulfonate, Türkischrotöl und Triäthanolamin zu nennen.
Verdünnt man die konzentrierte Schwefel lösung mit Wasser, das ausser dem Lösungs vermittler noch Alkohol enthält, so erhält man eine besonders für kosmetische Zwecke geeignete, rasch verdunstende. echte Schwefel lösung.
Die erhaltenen Lösungen zeigen weit höhere aktive Eigenschaften als die bekannten kol loidalen Schwefellösungen, in denen der Schwe fel sich nicht in echter Lösung befindet, und in der er sich auch durch Zusatz anderer Lösungsvermittler nicht in eine wahre Lösung überführen lässt.
<I>Beispiel 1:</I> 10 Gewichtsteile elementarer Schwefel werden in 45 Gewichtsteilen Cyclohexylamin gelöst, worauf diese Lösung zu 45 Gewichts teilen einer wässrigen Lösung zugefügt wird, die 7 Gewichtsteile Olein und 14 Gewichts teile Cyclohexylamin enthält. <I>Beispiel 2:</I> 5 Gewichtsteile elementarer Schwefel wer den in 45 Gewichtsteilen Cyclohexylarnirr ge löst; diese Lösung wird dann weiter mit einer Lösung, bestehend aus 5 Gewichtsteilen Was ser, 10 Gewichtsteilen Triäthanolainin und 35 Gewichtsteilen Alkohol vermischt.
<I>Beispiel 3:</I> 10 Gewichtsteile elementarer Sehwefel werden in 45 Gewichtsteilen Cyelohexylamin gelöst und der Lösung 75 Gewichtsteile einer wässrigen 25 ojoigen Kaliseife zugefügt.
Die nach Beispiel 3 hergestellten Lösun gen können als solche oder mit Wasser ver dünnt bei der Bekämpfung der Pflanzenschäd- linge als Spritzbrühen verwendet werden; sie können hierbei mit Nikotin, Pyrethrum usw. gemischt werden.
Process for the preparation of aqueous solutions of sulfur in elemental form. It is known to treat elemental sulfur with hydrogenated aromatic amines, such as. B. to bring cyclohexylamine, piperidine, nicotine, etc. into a concentrated solution that separates the sulfur in colloidal form when it is added to water.
However, these aqueous sulfur solutions have the disadvantage that they only contain the sulfur in colloidal form and have only a limited shelf life.
It has now been found that the concentrated sulfur solutions obtained with the hydrogenated aromatic amines can be converted into dilute, aqueous, genuine sulfur solutions of unlimited shelf life that can be used in practice (e.g. cosmetics, pest control, etc.) by converting the The resulting concentrated solutions of sulfur are mixed with aqueous solutions which contain at least one solubilizer. As such solubilizers are z.
These include, for example, the cyclohexylamine olein soaps, the alkali salts, especially the potassium soaps of oleic acid, fatty alcohol sulfonates, Turkish red oil and triethanolamine.
If the concentrated sulfur solution is diluted with water which, in addition to the solubilizer, also contains alcohol, one obtains a rapidly evaporating one which is particularly suitable for cosmetic purposes. real sulfur solution.
The solutions obtained show much higher active properties than the known colloidal sulfur solutions, in which the sulfur is not in real solution and in which it cannot be converted into a real solution even by adding other solubilizers.
<I> Example 1: </I> 10 parts by weight of elemental sulfur are dissolved in 45 parts by weight of cyclohexylamine, whereupon this solution is added to 45 parts by weight of an aqueous solution which contains 7 parts by weight of olein and 14 parts by weight of cyclohexylamine. <I> Example 2: </I> 5 parts by weight of elemental sulfur who dissolves the in 45 parts by weight of cyclohexylamine; this solution is then further mixed with a solution consisting of 5 parts by weight of what water, 10 parts by weight of triethanolainine and 35 parts by weight of alcohol.
<I> Example 3: </I> 10 parts by weight of elemental sulfur are dissolved in 45 parts by weight of cyelohexylamine and 75 parts by weight of an aqueous 25% potassium soap are added to the solution.
The solutions prepared according to Example 3 can be used as such or diluted with water in combating plant pests as spray liquors; they can be mixed with nicotine, pyrethrum, etc.
