Die neuen Verbindungen können nach an sich bekannten Verfahren erhalten werden, d. h. durch Umsetzung von (Alkylmercaptophenyl)-mercapto-methylhalogeniden mit Salzen von O,O-Dialkylthio- bzw:. -dithiophosphorsäuren. Die Reaktion wird bevorzugt bei Raumtemperatur bzw. leicht erhöhter Temperatur durch geführt und zweckmäßig in Gegenwart von inerten Lösungs- bzw. Verdünnungsmitteln vorgenommen. The new compounds can be obtained by processes known per se be, d. H. by converting (alkyl mercaptophenyl) mercapto methyl halides with salts of O, O-dialkylthio or :. -dithiophosphoric acids. The reaction is preferred at room temperature or slightly elevated temperature performed and appropriate made in the presence of inert solvents or diluents.
Die Anwendung der neuen Verbindungen geschieht in prinzipiell bekannter Weise, nämlich in Kombination mit festen oder flüssigen Streck- oder Verdünnungsmitteln. Als solche Streckmittel haben sich vor allem Kreide, Talkum, Bentonite und Kieselgur bewährt. Falls flüssige Kombinationen angewandt werden sollen, bestehen diese vorzugsweise aus wäßrigen Emulsionen, die unter Mitverwendung geeigneter Lösungshilfsmittel und handelsüblicher Emulgatoren leicht aus den vorstehenden Verbindungen hergestellt werden können. The new compounds are used in a manner that is known in principle Way, namely in combination with solid or liquid extenders or diluents. Chalk, talc, bentonite and kieselguhr have proven to be the most common such extenders proven. If liquid combinations are to be used, these preferably exist from aqueous emulsions, with the use of suitable solubilizers and commercially available emulsifiers are easily made from the above compounds can be.
