  Verfahren zum Schützen von Wolle, Haaren, Pelzwerk, Federn u. dgl. vor Mottenfrass. 



   Es wurde gefunden, dass halogensubstituierte Arylsulfon-oder Arylsulfoxydderivate, in denen die   S02- oder   SO-Gruppe auf der einen Seite an einen halogenierten Benzolkern, auf der andern Seite gebunden ist an R,   SR   oder   SO, R,   in denen R sein kann : Aryl, Aralkyl oder Alkyl, und wobei die unverzweigten oder verzweigten Aralkyl-oder die Alkylketten durch weitere Atome oder Atomgruppen, z. B. 



  Halogen, 0, S, SO,   S02, NH,   CO,   NH-CO   usw., substituiert bzw. unterbrochen sein können, in hervorragender Weise geeignet sind, Wolle, Haare, Federn, Pelzwerk u. dgl. dauernd vor Mottenfrass zu schützen. 



  Eine solche Wirkung dieser Schwefelderivate war keineswegs vorauszusehen, da bekanntlich der Eintritt von andern oxydierten Schwefelgruppen, wie die Sulfonsäuregruppe, in aromatischen Verbindungen ihre Giftigkeit stark herabsetzt oder ganz vernichtet. So wird das schon in kleinen Mengen giftige Martiusgelb (2. 4-Dinitro-1-naphthol) durch Überführung in die Sulfonsäure durchaus unschädlich gemacht, ein Beweis, dass die Sulfongruppe die giftige Nitrowirkung vollständig aufheben kann. Auch der Eintritt von andern, an sich indifferenten sauren Gruppen schwächt die physiologische Wirkung bedeutend oder hebt sie ganz auf. 



   Von den Verbindungen sind nachfolgend eine Anzahl erwähnt, von denen die meisten bekannt sind ; wo es sich um neue Verbindungen handelt, lassen sie sich nach bekannten Verfahren gewinnen :   4-4'- Dichlor-diphenylsulfoxyd   ; 4-4'- Dichlor-diphenyl-sulfon ;   4-4'- Dibrom-diphenylsulfoxyd   ; 
 EMI1.1 
 phenylsulfon-carbinol und seine Ester ; 3-Nitro-a-4'-chlorphenylsulfon-benzylalkohol ;   1- Thio-4-chlor-     phenyl-4'-chlorbenzolsulfonsäureester     (4-4'- Dichlor-diphenyl-disulfoxyd)   ; 4-Chlor-phenyl-sulfoessigsäurenitril. 



   4-4'-Dichlor-diphenyl-disulfon ;   4-4'- Dichlor-diphenyl-disulfon-methan,   Phenyl-2-2'-dichlor-diphe- 
 EMI1.2 
   Tri- (4-chlor-phenylsulfon)-methan   usw. 



   Schon in sehr geringen Konzentrationen eignen sich die genannten Sulfone und Sulfoxyde in hervorragender Weise zum dauernden Schutz von Wolle, Haaren, Pelzwerk, Federn u. dgl. vor Mottenfrass. Für die Verwendung kommen hauptsächlich Lösungen in billigen organischen Lösungsmitteln, wie Kohlenwasserstoffe, Chlorkohlenwasserstoffe, Alkohole, Ketone usw., oder deren Gemische in Frage. 



  Die zu schützenden Stoffe können durch Bestreichen, Bespritzen oder Eintauchen imprägniert werden. 



  Ebenso kommen diese Sulfone und Sulfoxyde in Kombination mit andern, für gleiche Zwecke schon bekannten Bekämpfungs-und Vertreibungsmittel in Betracht. 



   Beispiel : Man löst 2 Teile 4-4'-Dichlor-diphenylsulfoxyd in 998 Teilen Alkohol, behandelt Pelze, Federn oder Wolle durch Tauchen, zentrifugiert und trocknet. Die so behandelte Ware ist mottenecht ; es genügen schon verdünnter Lösungen, z. B.   l'/ooige,   um einen sehr guten Schutz zu erzielen. 



   An Stelle von   4-4'- Dichlor-diphenylsulfoxyd   können auch andre der genannten Verbindungen verwendet werden, z. B. 4-4'-Dichlor-diphenylsulfon oder   4-4'-3- Triehlor-diphenylsulfon.

  Method for protecting wool, hair, fur, feathers and the like like before moth damage.



   It has been found that halogen-substituted aryl sulfone or aryl sulfoxide derivatives in which the SO2 or SO group is bonded on one side to a halogenated benzene nucleus and on the other side to R, SR or SO, R, in which R can be: Aryl, aralkyl or alkyl, and where the unbranched or branched aralkyl or the alkyl chains are replaced by further atoms or groups of atoms, e.g. B.



  Halogen, O, S, SO, SO2, NH, CO, NH-CO, etc., can be substituted or interrupted, are excellently suited to wool, hair, feathers, fur and the like. Like. To protect permanently from moth damage.



  Such an effect of these sulfur derivatives was by no means foreseeable, since it is well known that the entry of other oxidized sulfur groups, such as the sulfonic acid group, greatly reduces or completely destroys their toxicity in aromatic compounds. Martius yellow (2, 4-dinitro-1-naphthol), which is toxic even in small amounts, is rendered harmless by converting it into sulfonic acid, proof that the sulfone group can completely cancel out the toxic effects of nitro. The entry of other, inherently indifferent, acidic groups also considerably weakens the physiological effect or completely eliminates it.



   A number of the compounds are mentioned below, most of which are known; where new compounds are involved, they can be obtained by known processes: 4-4'-dichloro-diphenylsulfoxide; 4-4'-dichloro-diphenyl-sulfone; 4-4'-dibromo-diphenylsulfoxide;
 EMI1.1
 phenylsulfon-carbinol and its esters; 3-nitro-α-4'-chlorophenylsulfon-benzyl alcohol; 1- thio-4-chlorophenyl-4'-chlorobenzenesulfonic acid ester (4-4'-dichloro-diphenyl-disulfoxide); 4-chloro-phenyl-sulfoacetic acid nitrile.



   4-4'-dichloro-diphenyl-disulfone; 4-4'-dichloro-diphenyl-disulfon-methane, phenyl-2-2'-dichloro-diphe-
 EMI1.2
   Tri- (4-chloro-phenylsulfone) -methane etc.



   Even in very low concentrations, the sulfones and sulfoxides mentioned are outstandingly suitable for the permanent protection of wool, hair, fur, feathers and the like. like before moth damage. Solutions in 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.



  These sulfones and sulfoxides can also be used in combination with other control and repellant agents which are already known for the same purposes.



   Example: 2 parts of 4-4'-dichloro-diphenylsulfoxide are dissolved in 998 parts of alcohol, furs, feathers or wool are treated by dipping, centrifuged and dried. The goods treated in this way are moth-proof; even dilute solutions are sufficient, e.g. B. l '/ oige, in order to achieve a very good protection.



   Instead of 4-4'-dichloro-diphenylsulfoxide, other of the compounds mentioned can also be used, e.g. B. 4-4'-dichloro-diphenylsulfone or 4-4'-3-trihlorodiphenylsulfone.
