Description
Die Erfindung betrifft neue Verbindungen der allgemeinen Formel I
Die ausgeprägte biocide Wirksamkeit von Verbindungen der allgemeinen Formel I war nicht vorherzusehen und ist deshalb überraschend. So ist z.B. die nachstehend aufgeführte Verbindung der Formel III bakteriologisch praktisch wirkungslos, obwohl sie chemisch ähnlich aufgebaut ist wie die Verbindungen der Formel I.The pronounced biocidal activity of compounds of the general formula I could not be foreseen and is therefore surprising. For example, the compound of the formula III listed below is practically ineffective in bacteriological terms, although it has a similar chemical structure to the compounds of the formula I.
In Analogie zur aliphatischen Aminreihe, wo z.B. die Verbindungen Octylamin und N-Octyl-propylendiamin gleichermaßen schwache bakteriologische Wirksamkeit und Verbindungen, wie Dodecylamin und N-Dodecyl-propylendiamin, vergleichbar gute bakteriologische Wirksamkeit zeigen, hätte man nämlich für die Verbindungen der Formeln I und III entweder die gleiche bakteriologische Wirksamkeit oder Unwirksamkeit erwarten müssen.In analogy to the aliphatic amine series, where, for example, the compounds octylamine and N-octyl-propylenediamine show equally weak bacteriological activity and compounds such as dodecylamine and N-dodecyl-propylenediamine show comparably good bacteriological activity, one would have for the compounds of the formulas I and III expect either the same bacteriological effectiveness or ineffectiveness.
Überraschend ist weiterhin, dass die erfindungsgemäßen Verbindungen I, verglichen mit oberflächenaktiven Aminen oder quaternären Ammoniumverbindungen, eine erheblich niedrigere Reizwirkung auf Haut und Schleimhäute ausüben, während bei anderen Baktericiden im allgemeinen eine besonders gute Baktericidie mit besonders starker Reizwirkung gekoppelt ist.It is also surprising that the compounds I according to the invention, compared with surface-active amines or quaternary ammonium compounds, exert a considerably lower irritant effect on the skin and mucous membranes, while with other bactericides a particularly good bactericide is generally coupled with a particularly strong irritant effect.
Ein besonderer Vorteil der erfindungsgemäßen Verbindungen I ist schließlich darin zu sehen, dass sie ihre vorzüglichen baktericiden Eigenschaften bereits bei sauren pH-Werten, z.B. bei pH 4, entfalten, während z.B. quaternäre Ammoniumverbindungen oder Ampholytseifen erst bei pH-Werten > 7 voll wirksam sind. Obendrein sind die erfindungsgemäßen Verbindungen I weit weniger empfindlich gegen Eiweiß und anionische Detergentien als z.B. quaternäre Ammoniumverbindungen. Damit eignen sich die erfindungsgemäßen Verbindungen ganz besonders für Anwendungen z.B. in der Getränkeindustrie, in Molkereien, in fisch- und fleischverarbeitenden Betrieben sowie in der Human- und Veterinärmedizin.Finally, a particular advantage of the compounds I according to the invention is that they develop their excellent bactericidal properties even at acidic pH values, e.g. at pH 4, while e.g. quaternary ammonium compounds or ampholyte soaps are only fully effective at pH values> 7. In addition, the compounds I according to the invention are far less sensitive to protein and anionic detergents than, for example, quaternary ammonium compounds. The compounds according to the invention are therefore very particularly suitable for applications, for example, in the beverage industry, in dairies, in fish and meat processing plants and in human and veterinary medicine.
Die Herstellung der erfindungsgemäßen Verbindungen erfolgt vorzugsweise durch Umsetzung von 2,6-Dichlorpyridin mit 1 bis 4 Mol eines Amins der allgemeinen Formel II

Danach wird die organische flüssige Phase heiß vom anorganischen Bodenkörper dekantiert und im Vakuum nicht umgesetztes N-Propylendiamin abdestilliert. Der Destillationsrückstand, der das erfindungsgemäße Reaktionsprodukt in roher Form enthält, wird nunmehr einer sogenannten Molekulardestillation unterworfen. Dabei werden 235 g Reinprodukt, welche bei einer Heizbadtemperatur von 120 bis 125°C und 0,1 mm Hg übergehen, erhalten.2 mol of N-octylpropylenediamine (373 g), 1 mol of 2,6-dichloropyridine (148 g), 1.5 mol of NaOH and 5 ml of water are introduced into a 1 l four-necked flask equipped with a stirrer, reflux condenser and thermometer. The contents of the flask are then heated to 130 to 140 ° C. for 3 hours while stirring. The organic liquid phase is then decanted from the inorganic sediment while hot and unreacted N-propylenediamine is distilled off in vacuo. The distillation residue, which contains the reaction product according to the invention in crude form, is now subjected to what is known as molecular distillation. This gives 235 g of pure product, which pass over at a heating bath temperature of 120 to 125 ° C. and 0.1 mm Hg.
