Description
Die antikryptogamen Eigenschaften der Phenole und ihrer Chlorderivate, insbesondere des Pentachlorphenols, sind bekannt.The anticryptogamic properties of phenols and their chlorine derivatives, especially pentachlorophenol, are known.
Diese Derivate werden zur Schutzbehandlung von Holz oder Zelluloseabfällen gegen Schimmel benutzt. Ein solches Produkt kann in gleicher Weise für die Winterbehandlung von Obstbäumen benutzt werden. Für diesen Zweck wurden Natriumsalze von Chlorphenolen in wässrigen Lösungen oder Lösungen von Chlorphenolen in organischen Lösungsmitteln benutzt, nachdem sie vorher eventuell mit Harzen geschmolzen wurden, um den Gebrauch von wenig kostspieligen Lösungsmitteln zu ermöglichen.These derivatives are used to protect wood or cellulose waste against mold. Such a product can be used in the same way for the winter treatment of fruit trees. For this purpose, sodium salts of chlorophenols in aqueous solutions or solutions of chlorophenols in organic solvents have been used, after possibly having previously been melted with resins in order to enable the use of less expensive solvents.
Wenn Chlorphenole in Lösung in einem organischen Lösungsmittel benutzt werden, ist diese Behandlungsweise sehr wirksam, denn das Phenol kann nicht mehr in Lösung gehen, ist also nicht abwaschbar. Jedoch ist in diesem Falle die Behandlung sehr beschwerlich. Im Gegensatz hierzu ist die Behandlung mit wässrigen Lösungen von Chlorphenolen wenig kostspielig, aber das Eindringen solcher Lösungen und die Schutzwirkung sind weniger gut.If chlorophenols are used in solution in an organic solvent, this type of treatment is very effective, because the phenol can no longer go into solution and is therefore not washable. However, in this case, the treatment is very troublesome. In contrast, the treatment with aqueous solutions of chlorophenols is not very expensive, but the penetration of such solutions and the protective effect are less good.
Es wurde nun befunden, dass verhältnismäßig konzentrierte Lösungen von Chlorphenolen und insbesondere von Pentachlorphenol in organischen Lösungsmitteln durch Hinzufügen eines geeigneten Emulsionsmittels in ein wenig Wasser emulgierbar erhalten werden können; die enthaltenen beständigen Emulsionen können im Augenblick des Gebrauchs im Wasser gelöst werden. Es wird derart eine erhebliche Ersparnis an organischen Lösungsmitteln erreicht.It has now been found that relatively concentrated solutions of chlorophenols and in particular of pentachlorophenol in organic solvents can be obtained emulsifiable by adding a suitable emulsifying agent in a little water; the contained permanent emulsions can be dissolved in water at the moment of use. A considerable saving in organic solvents is achieved in this way.
Nachstehend werden nur als Hinweis einige Ausführungsbeispiele der Erfindung genannt:A few exemplary embodiments of the invention are mentioned below as a reference only:
Beispiel 1:Example 1:
Die folgende Mischung wird in einer Kolloidmühle bereitet:The following mixture is prepared in a colloid mill:
Pentachlorphenol 5 - 15 Gewichts-%Pentachlorophenol 5 - 15% by weight
Anthrazenöl 40 - 60 Gewichts-%Anthracene oil 40 - 60% by weight
Wasser 10 - 50 Gewichts-%Water 10 - 50% by weight
Ammoniumsalz von Lignin-Ammonium salt of lignin
sulfonsäure in Pulverform 5 - 10 Gewichts-%sulfonic acid in powder form 5 - 10% by weight
Es wird eine beständige Paste erhalten, die sich vollständig in Wasser löst. Wässrige Lösungen, die 5-20% dieser Paste enthalten, werden auf das zu schützende Holz (Rüstholz oder dgl.) aufgestäubt. Das Holz wird hierdurch gut imprägniert und gegen den Schwamm ebenso wirksam geschützt, wie beim Gebrauch der viel teureren Lösungen von Pentachlorphenol in organischen Lösungsmitteln.A permanent paste is obtained which completely dissolves in water. Aqueous solutions containing 5-20% of this paste are dusted onto the wood to be protected (scaffolding wood or the like). The wood is well impregnated and protected against the sponge just as effectively as when using the much more expensive solutions of pentachlorophenol in organic solvents.
Beispiel 2:Example 2:
Pentachlorphenol 5 Gewichts-%Pentachlorophenol 5% by weight
Anthrazenöl 25 Gewichts-%Anthracene oil 25% by weight
Natrium-Abietat 10 Gewichts-%Sodium abietate 10% by weight
Abietinsäure 20 Gewichts-%Abietic acid 20% by weight
Wasser 40 Gewichts-%Water 40% by weight
werden mit Hilfe eines guten Rührwerks gemischt.are mixed with the help of a good mixer.
Beispiel 3:Example 3:
Pentachlorphenol 15 Gewichts-%Pentachlorophenol 15% by weight
Anthrazenöl 67 Gewichts-%Anthracene oil 67% by weight
Kondensationsprodukt vonCondensation product of
Äthylenoxyd mit Rizinol-Ethylene oxide with ricinol
säure 20 Gewichts-%acid 20% by weight
werden durch einfaches Rühren gemischt.are mixed by simply stirring.
Das in den vorstehenden Beispielen verwendete Anthrazenöl kann durch andere organische Produkte, die Chlorphenole lösen und nicht mit ihnen reagieren, ersetzt werden, z.B. Kreosotöl, Monochlornaphtalin oder Orthodichlorbenzol. In gleicher Weise kann man der Emulsion andere Schädlingsbekämpfungsmittel zusetzen, welche die Wirkung des Chorphenols vervollständigen, z.B. Hexachlorcyklohexan.The anthracene oil used in the above examples can be replaced by other organic products which dissolve chlorophenols and do not react with them, e.g. creosote oil, monochloronaphthalene or orthodichlorobenzene. In the same way, other pesticides can be added to the emulsion which complement the action of the chophenol, e.g. hexachlorocyclohexane.
Es können auch andere Emulsionsmittel und insbesondere auch Harzsäuresalze verwendet werden, als sie in diesen Beispielen aufgeführt sind.It is also possible to use other emulsifiers, and in particular also resin acid salts, than those listed in these examples.
Allgemein kann das Emulsionsmittel unter den Stoffen gewählt werden, welche die Phenolwirkung nicht neutralisiert.In general, the emulsifying agent can be selected from those substances which do not neutralize the phenolic action.
