Description
Mittel mit fungizider und insektizider Wirkung. Es ist bekannt, daß dem Furfurol, ebenso wie anderen Aldehyden, eine k-eim- und insektentötende Wirkung zukommt. Es wurde nun gefunden,daß Furfurol, seineHoniologen oder Derivate in hydriertem oder teilweise hydriertem Zustande oder in Gegenwart eines zyklischen, sauerstoffhaltigen Hydrierungsproduktes ein ausgezeichnetes Mittel mit fungizider und insektizider Wirkung darstellt.Means with fungicidal and insecticidal effects. It is known that the furfural, as well as other aldehydes, a k-germ and insecticidal effect comes to. It has now been found that furfural, its honiologues or derivatives in hydrogenated or partially hydrogenated states or in the presence of a cyclic, oxygen-containing one Hydrogenation product is an excellent agent with fungicidal and insecticidal properties Represents effect.
Zu diesem Zwecke wurde Furfurol in Gegenwart eines Katalysators mitWasserstoff behandelt. Ferner hat sich gezeigt, daß Furfurol in gleicher Weise durch einen Zusatz von hydrierten Phenolen, wie aromatischen Ketonen, haltbarer und wirksamer im genannten Sinne wird. Auch ein Zusatz von Furfuralkohol und insbesondere von hydriertem Furfuralkohol wirkt in hervorragender Weise als Schutzmittel gegen die zu leichte Verharzung des Furfurols. Es hat sich ferner auch herausgestellt, daß die Anwesenheit einer derartigen hydrierten, sauerstoffbaltigen, organischen Verbindung die keirntötende Wirkung des Furfurols erhöht.For this purpose, furfural was mixed with hydrogen in the presence of a catalyst treated. It has also been shown that furfural can be added in the same way of hydrogenated phenols, such as aromatic ketones, more durable and effective in the aforementioned Sense becomes. Also an addition of furfural alcohol and especially hydrogenated furfural alcohol acts in an excellent way as a protective agent against the too easy gumming of the Furfurols. It has also been found that the presence of such hydrogenated, oxygen-containing, organic compound has the germicidal effect of furfural increased.
In gleicher Weise kann man dem Furfurol neben den obengenannten Verbindungen auch andere Stoffe, wie Phenol, Kresol und deren Chlorierungsprodukte, Phenolate, Seifen, Naphthalin usw., zusetzen, ohne die Wirksamkeit des Furfurols zu beeinträchtigen.In the same way, one can use furfural in addition to the above-mentioned compounds also other substances such as phenol, cresol and their chlorination products, phenolates, Add soaps, naphthalene, etc., without affecting the effectiveness of the furfural.
Zur Herstellung von keim- und insektentötenden Mitteln aus Furfurol können belie-bige bekannte Verfahren benutzt werden, durch die unter Anwendung von Wasserstoff oder wasserstoffenthaltenden Gasen eine teilweise oder vollständige Hydri-erung bewirkt wird. Als Katalysatoren können dabei z. B. Paladiummohr, fein verteiltes Nickel, Platin usw. verwendet werden. Die Hydrierung kann in bekannterWeise auch in Dampfform ausgeführt werden, indem man beispielsweise die Dämpfe des Furfurols über erhitzte, mit Katalysatoren beladene Kontaktmittel leitet. Die Anlagerung von Wasserstoff läßt sich auch auf elektrochemischem Wege durchführen. Any known processes can be used to produce germicides and insecticides from furfural, by means of which partial or complete hydration is effected using hydrogen or hydrogen-containing gases. The catalysts can be, for. B. palladium black, finely divided nickel, platinum, etc. can be used. The hydrogenation can also be carried out in a known manner in vapor form, for example by passing the furfural vapors over heated catalyst-laden contact means. The addition of hydrogen can also be carried out electrochemically.
Man hat auch bereits Furfurol in Gegenwart von Säuren der Einwirkung von Wasserstoff entwickelnden Metallen ausgesetzt. Die dabei entstehenden harz- bzw. lackartigen Körper haben jedoch keine Verwendung als Schädlingsbekämpfungsmittel gefunden.One has also already had furfural in the presence of acids of the action exposed to hydrogen evolving metals. The resulting resinous However, or lacquer-like bodies have no use as pesticides found.
