Description

Verfahren zur Unterdrückung des Wachstums von Mikroorganismen in zersetzlichen Materialien Es wurde gefunden, daß Verbindungen, die neben Hydroxylgruppen noch an Kohlenstoff gebundene Cyangruppen enthalten, das Wachstum von Mikroorganismen und Pilzen außergewöhnlich wirksam unterdrücken und sich für Zwecke der Konservierung zersetzlicher Materialien sowie der Desinfektion gut eignen. Unter den in Betracht kommenden Verbindungen sind namentlich die Cyanphenole mit besonderem Vorteil verwendbar. Auch Abkömmlinge von Verbindungen der gekennzeichneten Art, wie Salze, Ester, Äther oder Substitutionsprodukte, insbesondere Halogenverbindungen der Cyanphenole und -naphthole, vermögen ähnliche Wirkungen auszuüben wie die Stammverbindungen.Method of suppressing the growth of microorganisms in decomposing Materials It has been found that compounds in addition to hydroxyl groups still contain cyano groups bonded to carbon, the growth of microorganisms and mushrooms exceptionally effective in suppressing and for preservation purposes decomposable materials as well as disinfection. Among the eligible In particular, the cyanophenols can be used with particular advantage. Also derivatives of compounds of the type indicated, such as salts, esters, ethers or substitution products, in particular halogen compounds of cyanophenols and -naphthols, are able to exert effects similar to those of the parent compounds.

Die neuen Mittel haben den Vorzug, daß sie mit hoher Wirksamkeit (die Hemmungskonzentration z. B. des p-Cyanphenols gegen Penicillium glaucum und Bacterium coli beträgt 0,075 bzw. o,o6) in den weitaus meisten Fällen Geruchlosigkeit und Farblosigkeit vereinigen und im Vergleich zu ähnlich gebauten Verbindungen gut wasserlöslich sind. Sie können auch in Verbindung mit anderen Konservierungsmitteln, wie Halogenphenolen, Oxybenzoesäureestern usw., gebraucht werden. Ihre Anwendung kann sowohl in Substanz wie auch in Form von Lösungen oder Suspensionen in den verschiedensten Dispergiermitteln erfolgen.The new agents have the advantage that they combine odorlessness and colorlessness with high effectiveness (the inhibitory concentration, for example of p-cyanophenol against Penicillium glaucum and Bacterium coli, is 0.075 or 0.06) in the vast majority of cases and in comparison to compounds with a similar structure are readily soluble in water. They can also be used in conjunction with other preservatives such as halophenols, oxybenzoic acid esters, etc. They can be used both in bulk and in the form of solutions or suspensions in a wide variety of dispersants.

Beispiel i Knochenleim wird mit o,o5 °/o p-Cyanphenol versetzt. Auch nach monatelangem Stehen tritt kein Pilzbefall ein.Example i Bone glue is mixed with 0.05% p-cyanophenol. Even no fungal attack occurs after standing for months.

Beispiel e . Photographische Gelatine, die einen Zusatz von o,i °/o o-Cyanphenol erhält, bleibt frei von Mikroorganismen.Example e. Photographic gelatin containing an addition of o, i ° / o o-cyanophenol remains free of microorganisms.
