Description
Es wurde gefunden, daß Oxime mit Vorteil als Desinfektions- und Konservierungsmittel
verwendbar sind. Diese Verbindungen zeichnen sich, durch eine hohe Wirksamkeit gegen
Mikroorganismen bei guter Beständigkeit und fast vollkommener Geruchlosigkeit aus.
Die Löslichkeit in Wasser genügt in der Regel in Anbetracht der starken Wirksamkeit
zur Erzielung der erstrebten Wirkung. Konzentrierte Lösungen kann man, wie dies auch
in anderen Fällen bekannt ist, durch Verwendung der leicht löslichen Salze der Oxime mit
anorganischen oder organischen Basen sowie auch durch Zuhilfenahme von Lösungsvermittlern
herstellen.
Unter den als Desinfektions- und/oder Konservierungsmitteln geeigneten Oximen
seien z. B. Aldoxime, wie die des Formaldehyds, Acetaldehyd«, Butyraldehyds,
Oenanthaldehyds, Palmitinaldehyds, Aeroleinis,
Crotonaldehyds, oder Ketoxime, wie die des Aceton®, Methyläthylketons, Butyrons,
Caprinons, Methylnonylketons, Stearons, Mesitylo'xyds, Phorons, Diaeetyls,
Acetylacetone, Acetonylacetons, Acetessigesters, Lävulinsäureäthyl- oder -dodecylesters,
der Meso'xal säure, des Aoetylcarbinols,
Ketobuitanols, Diacetonalkohols, Cyclohexanonis
und Ketodekahydronaphthalins genannt.
Als besonders wirksam haben sich diejenigen Oxime erwiesen, die einen aromatischen
Rest führen, so z. B. die Oxime des Benzaldehyds, p-Tolylaldehyds, p-Isopropyl-
Claims (2)
1. Verwendung von Oximen als Desinfektions-
und Konservierungsmittel.
2. Desinfektions- und Konservierungsmittel enthaltend Oxime.
