Description
Verfahren zur Herstellung von wasserlöslichen Schädlingsbekämpfungsmitteln in fester Form. In dem Patent 43 0 7 12, Anspruch 3, ist ein Verfahren zur Herstellung für die Schädlingsbekämpfung geeigneter Staffe beschrieben, das dadurch gekennzeichnet ist, daß man Lösungen von Metalloidverbindungen in durch Säure zersetzbarer Form mit den Alkaliverbindungen solcher hochmolekularen Säuren versetzt, welche aus fossilen Brennstoffen, gegebenenfalls nach deren Oxydation, nach bekannten Methoden gewonnen werden.Process for the preparation of water-soluble pesticides in solid form. Patent 43 0 7 12, claim 3, describes a process for the production of pest control suitable stuffing, which is characterized in that solutions of metalloid compounds in acid-decomposable form are mixed with the alkali compounds of such high molecular weight acids, which are derived from fossil fuels , optionally after their oxidation, are obtained by known methods.
Bei der weiteren Bearbeitung hat sich nun gezeigt, daß man an Stelle der dort genannten unlöslichen Produkte wasserlösliche Produkte in fester Form gewinnen kann, welche die Metalloide enthalten, wenn man statt der Alkaliverbindungen der genannten hochmolekularen Säuren diese Säuren selbst ohne Zusatz einer stärkeren Säure verwendet.In further processing it has now been shown that one in place of the insoluble products mentioned there obtain water-soluble products in solid form can, which contain the metalloids if, instead of the alkali compounds, the called high molecular acids these acids themselves without the addition of a stronger one Acid used.
So kann man z. B. aus Alkalipolysulfiden mittels dieser Säure Schwefel, aus Sulfoarseniaten Schwefelarsen, aus Aluminaten Alunüniurnoxydhydrat in wasserlöslicher Form gewinnen. Die so gewonnenen Produkte sind in fester Form luftbeständig und im kalten Wasser leicht löslich. Sie eignen sich in vorzüglicher Weise zur Bekämpfung von Schädlingen aller Art. B eis pi el i. Eine Lösung von 34 Teilen Schwefelammonium in 2ooTeilen Wasser wird mit Schwefel gesättigt, hierauf mit 5 5 Teilen einer durch Oxydation von Braunkohle erhältlichen hochmolekularen Säure versetzt und zur Trockne gedampft. Der feste braune Rückstand löst sich leicht in Wasser und ist ein sehr wirksames Fungizid. Beispiel 2. 55Teile Aluminiumsulfat werden in 1500 Teilen Wasser gelöst und 4oTeile Atznatron in 5oo Teilen Wasser zugefügt. In der erhaltenen Natriumaltiminatlösung werden unter gutem Rühren 6oTeile der durch Extraktion (nach vorheriger Oxydation) von Torf erhaltenen hochmolekularen Säuren gelöst und die Masse zur Trockne verdampft. DerRückstand löst sich leicht in Wasser. So you can z. B. from alkali polysulfides by means of this acid sulfur, from sulfoarseniates arsenic sulfur, from aluminates Alunüniurnoxydhydrat in water-soluble form. The products obtained in this way are air-resistant in solid form and easily soluble in cold water. They are particularly suitable for combating pests of all kinds. B eis pi el i. A solution of 34 parts of sulfur ammonium in 2oo parts of water is saturated with sulfur, 5 5 parts of a high molecular acid obtainable by oxidation of lignite are then added and the mixture is evaporated to dryness. The solid brown residue dissolves easily in water and is a very effective fungicide. Example 2. 55 parts of aluminum sulfate are dissolved in 1500 parts of water and 40 parts of caustic soda in 500 parts of water are added. 60 parts of the high molecular weight acids obtained by extraction (after previous oxidation) of peat are dissolved in the sodium aliminate solution obtained, and the mass is evaporated to dryness. The residue easily dissolves in water.
