Description
Mittel mit insektizider, fungizider und bakterizider Wirkung Es ist bekannt, daß man Chloral mit P'henolen, wie Phenol, Anisol, Phenetol, Resorcin, in Anwesenheit von katalytisch wirkenden Substanzen, wie z. B. Schwefelsäure, zu Kondensationsprodukten der allgemeinen Formel C C13 * C H (ROH), vereinigen kann.Means with insecticidal, fungicidal and bactericidal effects It is known that chloral can be mixed with phenols such as phenol, anisole, phenetol, resorcinol, in the presence of catalytically active substances such. B. sulfuric acid, too Condensation products of the general formula C C13 * C H (ROH) can combine.
Es wurde nun gefunden, daß derartige Kondensationsprodukte aus Chloral und aromatischen Oxyverbindungen sehr wirksame Schädlingsbekämpfungsmittel, insbesondere gegen Pflanzenkrankheiten, darstellen, da sie infolge der Eigenwirkung ihrer Komponenten gleichzeitig insektizid, fungizid und auch bakterizid wirksam sind.It has now been found that such condensation products from chloral and aromatic oxy compounds are very effective pesticides, in particular against plant diseases, as they are due to the inherent effects of their components are insecticidal, fungicidal and bactericidal at the same time.
In besonders hohem Grade finden sich diese drei Eigenschaften in denjenigen Kondensationsprodukten vereinigt, die durch Umsetzung von Chloral mit Oxydiphenylen erhalten werden können. Als derartige Oxydiphenyle kommen vorzugsweise z. B. das o-Oxydiphenyl, das p-Oxydiphenyl sowie die Dioxydiphenyle und die Substitutionsprodukte und sonstigen Derivate der Oxydiphenyle, insbesondere ihre halogenhaltigen Derivate, in Betracht.These three qualities are to be found in them to a particularly high degree Combined condensation products obtained by reacting chloral with oxydiphenylene can be obtained. As such oxydiphenyls are preferably such. B. that o-Oxydiphenyl, p-Oxydiphenyl and the dioxydiphenyls and the substitution products and other derivatives of oxydiphenyls, in particular their halogen-containing derivatives, into consideration.
Die Herstellungsweise der Kondensationsprodukte unterscheidet sich nicht von der bereits aus der Fachliteratur bekannten Arbeitsweise der Vereinigung von Chloral mit Phenolen. Beispielsweise verläuft die Herstellung des Kondensationsprodukts aus Chloral und o-Oxydiphenyl folgendermaßen: r Mol Chloral und :2 Mol o-Oxydiphenyl werden ineinander gelöst. Zu dem Gemisch wird unter Eiskühlung und gutem Umrühren allmählich das gleiche Volumen konzentrierte Schwefelsäure zugesetzt, wobei die Temperatur nicht über 50° steigen soll. Aus dem Reaktionsgemisch, scheidet sich hierbei das rohe Kondensationsprodukt als Körper von kittartiger Beschaffenheit ab, der nach beendeter Reaktion abgetrennt und mit kaltem Wasser so lange verknetet wird, bis er fest und bröcklig geworden ist. Nach völliger Entfernung der anhaftenden Schwefelsäure wird das Produkt getrocknet und aus Eisessig umkristallisiert. Das hierbei erhaltene Reinprodukt ist kristallinisch und schmilzt bei r78°. Es hat die Konstitution eines Bis- (oxydiphenylen)-trichloräthans.The way the condensation products are manufactured is different not from the way the association works, which is already known from the specialist literature of chloral with phenols. For example, the production of the condensation product takes place from chloral and o-oxydiphenyl as follows: r moles of chloral and: 2 moles of o-oxydiphenyl are dissolved into each other. The mixture is added with ice-cooling and thorough stirring gradually the same volume of concentrated sulfuric acid is added, whereby the temperature should not rise above 50 °. From the reaction mixture separates here the crude condensation product as a body of putty-like nature from, which is separated after the reaction has ended and kneaded with cold water for so long until it becomes firm and crumbly. After complete removal of the adhering Sulfuric acid, the product is dried and recrystallized from glacial acetic acid. That The pure product obtained in this way is crystalline and melts at r78 °. It has Constitution of a bis (oxydiphenylene) trichloroethane.
Die beschriebenen Kondensationsprodukte können zur Bekämpfung von Schädlingen in jeder hierfür geeigneten Form verwendet werden, also z. B. in festem oder verflüssigtem Zustande, als Dämpfe oder Lösungen, als Pasten, als durch Aufsaugung in porösen Trägerstoffen erhaltene Pulver, als Seifen oder Salben. Sie können ferner für sich allein oder im Gemisch mit anderen Stoffen verwendet werden.The condensation products described can be used to combat Pests can be used in any suitable form, e.g. B. in solid or in a liquefied state, as vapors or solutions, as pastes, as by absorption Powders obtained in porous carriers, as soaps or ointments. You can also can be used on their own or in a mixture with other substances.
