  Holzkonservierungsmittel. 



   Die gute Wirkung des Arsens als Holzkonservierungsmittel ist bekannt. Anorganische Arsenverbindungen sind hier wie auch in anderen Fällen weniger wirksam als organische und 
 EMI1.1 
 
 EMI1.2 
 
 EMI1.3 
 nur solche Verwendung gefunden, die ausser dem Arsen noch andere Substituenten tragen. 



   Es wurde nun die überraschende Beobachtung gemacht, dass unsubstituierten Arsinoxyden, wie Methylarsinoxyd, Phenylarsinoxyd, Methylphenylarsinoxyd, Naplitylarsinoxyd weitaus die grösste Wirksamkeit als Holzkonservierungsmittel zukommt. Zur Verwendung werden die Verbindungen, soweit sie in Wasser   unlöslich   sind, in geeigneten   Losungsmitteln, wie   Alkohol u. a. aufgenommen und in der Weise verdünnt, dass entweder Lösungen oder Emulsionen erhalten werden. Das so behandelte Holz ist. nicht nur gegen pflanzliche, sondern auch   gegen tierische Schädlinge, wie   z. B. Termiten geschützt. 



   Beispiel 1.   20   Gewichtsteile Phenylarsinoxyd   (Annalen 201,   Seite 200) werden in 80 Gewichtsteilen Alkohol heiss gelost und mit Wasser soweit verdünnt, dass eine   0'10/oigne

Beispiel 2. Eine Lösung von 1 Gewichtsteil Phenylarsinoxyd in 5 Gewichtsteilen Alkohol wird mit 1000 Gewichtsteilen Teer verdünnt und zur Holzimprägnierung verwandt. 



   Beispiel 3. Eine Mischung aus 50 Gewichtsteilen einer 20%igen alkoholischen Lösung 
 EMI1.5 
   1-20   und 10 Gewichtsteilen eines Netzmittels, wie es z. B.   nach D. R. P. Nr.   336558 durch Einwirkung von Naphtalinsulfosäure auf Isopropylalkohol erhalten werden kann, lässt sich mit jeder beliebigen Wassermenge verdünnen und so zur   Holzimprägnierung verwenden. Durch den   Zusatz von Netzmitteln wird ein besseres Eindringen in das Holz erreicht. 



   Beispiel 4. Eine   0'004%igue   Lösung von Methylarsinoxyd in einer den   Beispipleu 1- ; 3   entsprechenden Weise hergestellt, verhindert das Wachstum von Coniophora   cerphplla unù   Ceratostomella. 



   Beispiel 5. Eine   0#006%ige Lösung von ss-Naphtylarsinoxyd,   wie in den vorigen Beispielen beschrieben hergestellt. verhindert die Entwicklung von   Coniophora cerebelia.

  Wood preservatives.



   The good effect of arsenic as a wood preservative is well known. Inorganic arsenic compounds are here as in other cases less effective than organic and
 EMI1.1
 
 EMI1.2
 
 EMI1.3
 found only those uses which carry other substituents in addition to arsenic.



   The surprising observation has now been made that unsubstituted arsine oxides, such as methylarsine oxide, phenylarsine oxide, methylphenylarsine oxide and naplitylarsine oxide are by far the most effective as wood preservatives. To use the compounds, if they are insoluble in water, in suitable solvents such as alcohol and the like. a. taken up and diluted in such a way that either solutions or emulsions are obtained. The wood so treated is. not only against vegetable, but also against animal pests, such as. B. Termites protected.



   Example 1. 20 parts by weight of phenylarsine oxide (Annalen 201, page 200) are dissolved in 80 parts by weight of hot alcohol and diluted with water to such an extent that a 0'10%
 EMI1.4
 
Example 2. A solution of 1 part by weight of phenylarsine oxide in 5 parts by weight of alcohol is diluted with 1000 parts by weight of tar and used for impregnating wood.



   Example 3. A mixture of 50 parts by weight of a 20% alcoholic solution
 EMI1.5
   1-20 and 10 parts by weight of a wetting agent, as it is e.g. B. according to D.R.P. No. 336558 can be obtained by the action of naphthalene sulfonic acid on isopropyl alcohol, can be diluted with any amount of water and used for wood impregnation. The addition of wetting agents enables better penetration into the wood.



   Example 4. A 0'004% igue solution of methylarsine oxide in one of the examples 1-; 3 produced accordingly, prevents the growth of Coniophora cerphplla unù Ceratostomella.



   Example 5. A 0 # 006% solution of β-naphthylarsine oxide prepared as described in the previous examples. prevents the development of Coniophora cerebelia.
