Description
Verfahren zur Herstellung bactericid wirkender ß-Phenoxyäthyl-ammoniumverbindungen Es ist bekannt, daß Aryloxyalkyl-ammoniumverbindungen, die sich von zweiwertigen Phenolen ableiten, desinfizierende Eigenschaften besitzen.Process for the production of bactericidal ß-phenoxyethylammonium compounds It is known that aryloxyalkyl-ammonium compounds, which differ from divalent Derive from phenols, have disinfecting properties.
Es wurde nun gefunden, daß neue, wertvolle Verbindungen erhalten werden, wenn man quaternäre Verbindungen des N-ß-Phenoxyäthyl-dimethylamins herstellt, die am quaternären Stickstoffatom einen Kohlenwasserstoffrest mit mindestens 8 Kohlenstoff atomen enthalten. Der Vorteil des vorliegenden Verfahrens besteht demnach darin, daß man einfachere Ausgangsstoffe verwendet, wobei Stoffe erhalten werden, die überraschenderweise ebenso wertvolle Eigenschaften aufweisen, wie die obengenannten Verbindungen. Erwähnt seien beispielsweise folgende Endstoffe: ß-Phenoxyäthyl-dimethyldodecyl-ammoniumbromid, ß-Phenoxyäthyl-dimethyl-dodecyl-ammoniumchlorid, ß-Phenoxyäthyldimethyl-dodecyl-p-toluolsulfonat, ß-Phenoxyäthyldimethyl-octyl-ammoniumbromid, ß-Phenoxyäthyldimethyl-äthylhexyl-ammoniumbromid oder ß-Phenoxyäthyl-dimethyl-hexadecyl-ammoniumbromid.It has now been found that new, valuable compounds are obtained, when preparing quaternary compounds of N-ß-phenoxyethyl-dimethylamine, the a hydrocarbon radical with at least 8 carbon atoms on the quaternary nitrogen atom contain atoms. The advantage of the present method is therefore: that you used simpler starting materials, substances are obtained that surprisingly have properties that are just as valuable as the compounds mentioned above. Mentioned are for example the following end products: ß-phenoxyethyl-dimethyldodecyl-ammonium bromide, ß-phenoxyethyl-dimethyl-dodecyl-ammonium chloride, ß-phenoxyethyldimethyl-dodecyl-p-toluenesulfonate, ß-phenoxyethyldimethyl-octyl-ammonium bromide, ß-phenoxyethyldimethyl-ethylhexyl-ammonium bromide or ß-phenoxyethyl-dimethyl-hexadecyl-ammonium bromide.
Die Verbindungen können dadurch hergestellt werden, daß man ß-Phenoxyäthyl-dimethyl-amin mit solchen Mitteln quaternisiert, die einen Kohlenwasserstoffrest mit mindestens 8 Kohlenstoffatomen einzuführen vermögen oder daß man ß-Phenoxyäthylamin, das am Stickstoff einen Kohlenwasserstoffrest mit mindestens 8 Kohlenstoffatomen und i WässerstoffafoM oder .-einen Methylrest enthält, mit methylierenden Mitteln behandelt. Als quaternisierende Mittel lassen sich reaktionsfähige Ester von Alkoholen mit mindestens 8 Kohlenstoffatomen# bzw. des Methanols; beispielsweise Ester der Halogenwasserstoffsäuren, aliphatischer, aroniatischer oder araliphatischer Sulfonsäuren, wie der p-I'oluolsulfonsäure, verwenden.The compounds can be prepared by adding ß-phenoxyethyl-dimethyl-amine quaternized with such agents that have a hydrocarbon radical with at least 8 carbon atoms are able to introduce or that one ß-phenoxyethylamine, which is on Nitrogen is a hydrocarbon radical with at least 8 carbon atoms and i Hydrogen afoM or - contains a methyl radical, treated with methylating agents. Reactive esters of alcohols can be used as quaternizing agents at least 8 carbon atoms or of the methanol; for example esters of hydrohalic acids, aliphatic, aromatic or araliphatic sulfonic acids, such as p-toluenesulfonic acid, use.
Eine andere Ausführungsform des Verfahrens besteht darin, daß man ß-Oxyäthyl-dimethyl-ammoniuniverbindungen, die am quaternären @Stickstoffatoin einen Kohlenwasserstoffrest mit mindestens 8 Kohlenstoffatomen aufweisen, bzw. ihre reaktionsfähigen Derivate mit Phenol, bzw. seinen funktionellen reaktionsfähigen Abkömmlingen umsetzt. So kann man z. B. ß-Halogenäthyl-ammoniumverbindungen mit Phenol oder aber ß-Oxyäthyl-aminoniumverbindungen mit einem entsprechenden Ilalogenberizol zur Reaktion bringen. Die zur Umsetzung verwendeten ß-Oxyäthyl-amttonitimverbindungen bzw. ihre reaktionsfähigen Derivate lassen ,ich, sofern sie nicht bekannt sind, in an sich üblicher Weise herstellen.Another embodiment of the method is that one ß-Oxyäthyl-dimethyl-ammoniuniverbindungen, which at the quaternary @Stickstoffatoin a Have hydrocarbon radicals with at least 8 carbon atoms, or their reactive ones Reacts derivatives with phenol or its functionally reactive derivatives. So you can z. B. ß-Haloethyl-ammonium compounds with phenol or ß-Oxyäthyl-aminoniumverbindungen react with an appropriate ilalogenberizole. The implementation ß-Oxyäthyl-amttonitimverbindungen or their reactive derivatives used let me, if they are not known, made in a conventional manner.
Die neuen Verbindungen können ferner auch gewonnen werden, indem man reaktionsfähige Ester des ß-Phenoxyäthanols, insbesondere Ester der Halogenwasserstoffsäuren, auf Dimethylamine, die ain Stickstoff durch einen Kohlenwasserstoffrest finit mindestens 8 Kohlenstoffatomen substituiert sind, einwirken läßt. Zur Herstellung dieser zur Umsetzung verwendeten Ester kann man z. B. von Phenol und reaktionsfähigen Estern des Glykols ausgehen.The new compounds can also be obtained by reactive esters of ß-phenoxyethanol, especially esters of hydrohalic acids, on dimethylamines, which are finite at least in nitrogen through a hydrocarbon residue 8 carbon atoms are substituted, can act. To produce this for Implementation used esters can be, for. B. of phenol and reactive esters run out of glycol.
Die verfahrensgemäß erhaltenen Stoffe sind in Wasser lösliche und zum Teil gut kristallisierende Verbindungen. Sie besitzen gut desinfizierende und konservierende Eigenschaften und können daher auf den verschiedensten Gebieten als Desinfektions- und Konservierungsmittel Verwendung finden. So sind sie geeignet für die Desinfektion der Haut, z. B. der Hände, von Instrumenten, Verbandstoffen, Wäsche od. dgl., sowie auch zur Desinfektion bzw. Konservierung von Nahrungs- oder Futtermitteln. Sie können allein öder gemischt in Lösung oder als Emulsion und/oder mit anderen wirksamen oder inerten Stoffen wie Salben oder auch in Form von Trockenpulvern zur Anwendung kommen. $eispiel i Teile ß-Phenoxyäthyl-dimethylainin werden 2 :Stunden im kochenden Wasserbad mit i i Teilen Dodecylbromid erwärmt. Man erhält in guter Ausbeute ß-Phenoxyätltyl-dimethyl-dodecyl-ammoniumbromid, das nach dem Umkristallisieren aus Aceton bei 112° schmilzt. Es ist ein weißes Kristallpulver, das gut und mit neutraler Reaktion in Wasser löslich ist.The substances obtained according to the process are soluble in water and compounds that crystallize well in some cases. They have good disinfectant and preservative properties and can therefore be used in a wide variety of areas Disinfectants and preservatives are used. So they are suitable for disinfecting the skin, e.g. B. hands, instruments, bandages, Laundry or the like, as well as for the disinfection or preservation of food or Feed. They can be used alone or mixed in solution or as an emulsion and / or with other active or inert substances such as ointments or in the form of dry powders come into use. Example i parts of ß-phenoxyethyl-dimethylamine are 2 hours warmed in a boiling water bath with i i parts of dodecyl bromide. You get in good Yield ß-Phenoxyätltyl-dimethyl-dodecyl-ammonium bromide, which after recrystallization from acetone melts at 112 °. It is a white crystal powder that is good and with neutral reaction is soluble in water.
