  Verfahren zum Vertreiben und Bekämpfen von Insekten und deren Larven. 



   Es wurde gefunden, dass man neue, wertvolle Mittel zum Vertreiben und Bekämpfen von
Insekten und deren Larven erhält, wenn man in üblicher Anwendungsweise Thianthren, dessen
Derivate oder   Substitntionsprod) 1kte,   deren zyklisch gebundener Schwefel nicht in der Oniumform vorliegt, in Lösungen oder Mischungen verwendet.

   Verbindungen solcher Art sind in grosser Zahl   bekannt. lis   folgenden seien einige derselben aufgezählt, ohne dadurch den Umfang der vorliegenden
Erfindung beschränken zu wollen :
Thianthren, 2. 6-Dimethylthianthren, 1.3. 5.   7-Tetramethylthianthren, 2-Chlorthianthren,   2. 7-Di-   chlorthianthren, 2. 7-Dichlor-3. 6-dimethylthianthren, 4. 5-Dichlor-1. 8-dimethylthianthren, Dimethoxythianthren (C. 1922, 1., 818), 2.3. 6. 7-Tetramethoxythianthren, Dinitrothianthren BI (3) 15 ;

   423, 3-Nitro-6-methylthianthren, 3-Nitro-8-methoxy-5-methylthianthren, 6-Chlor-3-nitrothianthren, 5. 8-Di-     chlor-3-nitrothianthren,   3-amino-6-methylthianthren-ehlorhydrat,   Thianthlendicarbonsäure   (C. 1922,
1., 818), Thianthrensulfonsäure (C. 1927, 1., 360), Naphthianthien usw., feiner die S-Oxyde obiger
Verbindungen, wie beispielsweise : Thianthren-S-oxyd, Thianthren-S-dioxyd, Thianthren-mono-oder - disulfon, 2. 6-Dimethylthianthren-S-oxyde, 2.3. 6.   7-Tetramethoxythianthren-S-oxyde   usw., oder die Disulfide, die sich von den Thianthrenverbindungen ableiten, beispielsweise 3.7-Dimethoxy-
2. 6-dioxythianthren-disulfid usw. Die meisten dieser Verbindungen sind im Schrifttum beschrieben ; sofern sie unbekannt sind, lassen sie sich nach üblichen Methoden herstellen. 



   Die genannten Thianthrene eignen sich beispielsweise hervorrager. d zum Schützen von Wolle,
Haaren, Pelzwerk, Federn   u. dgl.   vor Mottenfrass. Bereits in sehr geringen Konzentrationen verleihen sie der behandelten Ware zuverlässigen Schutz. Für die Verwendung kommen hauptsächlich Lösungen in Wasser oder billigen organischen Lösungsmitteln, wie Kohlenwasserstoffen, Chlorkohlenwasser- stoffen, Alkoholen, Ketonen usw. oder deren Gemischen in Frage. Die zu   schützenden   Stoffe können durch Bestreichen, Bespritzen oder Eintauchen imprägniert werden. Ausserdem können die Thianthrene in Ölen, Fetten und Cremen emulgiert oder als Zusatz zu Pulvern oder überhaupt in allen für die Zwecke der Schädlings-, insbesondere Insektenbekämpfung üblichen Anwendungsformen verwendet werden. 



   Ebenso kommen sie in Kombination mit andern, für gleiche Zwecke schon bekannten Bekämpfungs- und Vertreibungsmitteln in Betracht. 



    Beispiel l : Man lost 20 Teile Thianthren oder eine andere der oben aufgezählten Verbindungen,   beispielsweise 2. 6-Dimethylthianthren, 2.   7-Dichlor-3.   6-dimethylthianthren, oder Thianthren-S-oxyd u. a.   in 980 Teilen Alkohol, behandelt Pelze, Federn oder Wolle durch Tauchen, zentrifugieit undtroeknet.   



     Die so behandelte Ware ist mottenecht   ;   es genügen schon verdünntere Lösungen, um einen befriedi-   genden Schutz zu erzielen. 



   Beispiel 2 : Bespritzt man tierische Schädlinge aus der Klasse der Insekten, beispielsweise
Stabheuschrecken, mit Lösungen, die Thianthren oder dessen Derivate oder Substitutionsprodukte, deren cyklisch gebundener Schwefel nicht in der Oniumform vorliegt, enthalten, so werden diese in ziemlich kurzer Zeit getötet.

  Process for driving away and controlling insects and their larvae.



   It has been found that one can find new, valuable means of dispelling and fighting
Insects and their larvae are obtained if one uses thianthrene in the usual manner, its
Derivatives or substitution products, the cyclically bound sulfur of which is not in the onium form, used in solutions or mixtures.

   Compounds of this type are known in large numbers. Some of them are enumerated below, without thereby reducing the scope of the present
Wanting to restrict the invention:
Thianthrene, 2. 6-dimethylthianthrene, 1.3. 5. 7-tetramethylthianthrene, 2-chlorothianthrene, 2. 7-dichlorothianthrene, 2. 7-dichloro-3. 6-dimethylthianthrene, 4. 5-dichloro-1. 8-dimethylthianthrene, dimethoxythianthrene (C. 1922, 1., 818), 2.3. 6. 7-tetramethoxythianthrene, dinitrothianthrene BI (3) 15;

   423, 3-nitro-6-methylthianthrene, 3-nitro-8-methoxy-5-methylthianthrene, 6-chloro-3-nitrothianthrene, 5. 8-dichloro-3-nitrothianthrene, 3-amino-6-methylthianthrene chlorohydrate, thianthlene dicarboxylic acid (C. 1922,
1., 818), thianthrene sulfonic acid (C. 1927, 1., 360), naphthianthias, etc., finer the S-oxides above
Compounds such as: thianthrene S-oxide, thianthrene-S-dioxide, thianthrene mono- or disulfone, 2. 6-dimethylthianthrene-S-oxides, 2.3. 6. 7-tetramethoxythianthrene-S-oxides, etc., or the disulfides which are derived from the thianthrene compounds, for example 3.7-dimethoxy-
2. 6-dioxythianthrene disulfide, etc. Most of these compounds are described in literature; if they are unknown, they can be produced using conventional methods.



   The thianthrenes mentioned are, for example, more suitable. d to protect wool,
Hair, fur, feathers, etc. like before moth damage. Even in very low concentrations, they give the treated goods reliable protection. Solutions in water or cheap organic solvents, such as hydrocarbons, chlorinated hydrocarbons, alcohols, ketones, etc., or mixtures thereof, are mainly suitable for use. The substances to be protected can be impregnated by brushing, spraying or dipping. In addition, the thianthrenes can be emulsified in oils, fats and creams or used as an additive to powders or in all of the application forms customary for the purpose of controlling pests, in particular insects.



   They can also be used in combination with other control and repellant agents that are already known for the same purposes.



    Example 1: 20 parts of thianthrene or another of the compounds listed above, for example 2. 6-dimethylthianthrene, 2. 7-dichloro-3, are dissolved. 6-dimethylthianthrene, or thianthrene-S-oxide u. a. in 980 parts of alcohol, treated fur, feathers or wool by dipping, centrifuging and drying.



     The goods treated in this way are moth-proof; even more dilute solutions are sufficient to achieve satisfactory protection.



   Example 2: If animal pests from the class of insects are sprayed, for example
Stick insects, with solutions that contain thianthrene or its derivatives or substitution products, the cyclically bound sulfur of which is not in the onium form, these are killed in a fairly short time.
