Description

Verfahren zur Herstellung konzentrierter Lösungen des Trimercuri-diaceton-hydrats Das von R e y n. o 1 @d s entdeckte Trimercuridiacetan-hydrat ist in Gegenwart von Alkali außerordentlich leicht polymerisierbar; dagegen ist die Verbindung ziemlich stabil, wenn man dafür Sorge trägt, daß die bei der Darstellung anwesenden Hydroxylionen rasch entfernt werden. In monomolekularer konzentrierter Form ist die Base bis jetzt nur in der Weise gewannen worden, daß man frisch gefälltes Quecksilberoxyd in Gegenwart von Bariumhydroxyd mit Aceton behandelte, alsdann den Baryt durch Kohlensäure ausfällte und aus der filtrierten Lösung durch Eindampfen das Hydrat in konzentrierter Form erhielt (Berichte der Deutschen Che.rnischen Gesellschaft, B,d. 38, S. 2677 bis 268o). Auch nach dieser Vorschrift ist eine Polymerisation schwer zu vermeiden; denn selbst wenn das Quecksilberoxyd auf das sorgfältigste alkalifrei gewaschen ist, tritt oft durch die Einwirkung des Bariurcnhydroxyds schon Polymerisativn ein, bevor die Umsetzung beendet ist.Process for the preparation of concentrated solutions of trimercuri diacetone hydrate The trimercuridiacetane hydrate discovered by R ey n. O 1 @ds is extremely easy to polymerize in the presence of alkali; on the other hand, the compound is quite stable if care is taken to remove the hydroxyl ions present in the preparation quickly. In monomolecular concentrated form the base has so far only been obtained by treating freshly precipitated mercury oxide in the presence of barium hydroxide with acetone, then precipitating the barite with carbonic acid and obtaining the hydrate in concentrated form from the filtered solution by evaporation (Reports of the German Chemical Society, B, d. 38, pp. 2677 to 268o). According to this rule, too, polymerization is difficult to avoid; for even when the mercury oxide has been carefully washed free of alkali, the action of the barium hydroxide often causes polymerisation to take place before the reaction has ended.

In stark verdünnter Lösung wurde das Trimercuri-diaceton-hydrat auch schon in der Weisse erhalten, daß eine verdünnte Quecksilberchloridlösung nut einem Gemisch von Aceton und überschüssiger Kalilauge versetzt und sodann dialysiert wurde (Zeitschrift für Chemie, Bld.7, S.254 bis 255). So dargestellte Lösungen gelatinieren bei einen Gehalt von 8 Prozent bereits nach wenigen Stunden und sind in sehr starker Verdünnung und bei Abwesenheit von Fremdstoffen einige Zeit haltbar.Trimercuri-diacetone hydrate was also found in a very dilute solution already received in the white that a dilute mercury chloride solution only one Mixture of acetone and excess potassium hydroxide solution was added and then dialyzed (Journal of Chemistry, Vol. 7, pages 254 to 255). Gelatinize the solutions presented in this way with a salary of 8 percent already after a few hours and are very strong Dilution and stable for some time in the absence of foreign matter.

Es wunde nun gefunden, daß man in einfacher und sicherer Weise zu konzentrierten Lösungen .der monomeren Base gelangt, wenn man konzentrierte Sub.limatlösungen in Gegenwart von Aceton und von Kochsalz mit Alkali behandelt, einen etwaiggen geringen Überschuß des. letzteren sogleich mit Säure fortnimmt und das Salz, sowohl das ursprünglich zugesetzte wie,das während der Reaktion entstandene in der Lösung beläßt.It sore now found that one can in a simple and safe manner too concentrated solutions of the monomeric base are obtained when using concentrated sub-limate solutions Treated with alkali in the presence of acetone and common salt, possibly a small amount Excess of the latter is immediately taken away with acid, and the salt, both the original added such as that which has arisen during the reaction is left in the solution.

Beispiel i Man löst 27 kg Sublämat unter Zusatz von Ekg Kochsalz in 5o l Wasser, fügt 12 bis 151 Aceton hinzu und gießt die Mischung unter Rühren in 5o1 einer auf 3o--liis 40° erwärmten vierfach normalen Natronlauge. Das ausfallende Quecksilberoxyd löst sich augenblicklich wieder auf, und man -erhält eine völlig klare Lösung, -die man sogleich mit so viel verdünnter Salzsäure versetzt, daß ein ganz geringer Niederschlag des schwerlöslicheri Salzsäuren Salzes ausfällt. Von diesem filtriert man ab und erhält so eine etwa 25prozentige haltbare Lösung der Base, die außerdem nur noch Kochsalz enthält. Salzsäure fällt aus ihr das salzsaure Salz, Natron- lauge fällt kein Quecksüberoxyd; bewirkt da- gegen nach kurzer -Zeit. T>alymerisation., Am- monsulfiid -fällt schwarzes. Quecksübersulfid. Erhitzen° auf . go. his «ioon bewirkt ebenfalls Polymerisation. Eiale noch weitere Konzen- tration muß im Vakuum bei niedrigerer Tem- peratur vorgenommen werden. Beispiel z 13,57 kg (-/2o Mol.) Quecksilberchlorid werden unter Zusatz von 5,8 lzg Natriuan- chlorid in 81 Wasser gelöst. Zu 16,661 Nor- malnatronlauge (i/10 Mol.) gibt man 51 Aceton und .gießt untergutem Umschütteln die Quecksüberchlorldlösung hinzu. Wenn nicht völlig klar, wird filtriert. Infolge der hohen, diejenige des Sublimats um das Mehrfache übertreffende bakteriziden und fungiziden Wirkung der Base und ihrer vergleichsweisen Unempfindlichkeit gegen Metalle sind derartige Lösungen für mannigfache Zwecke ider Desinfektion und Pilzbekämpfung gut verwendbar. Der Kochsalzgehalt ist dabei nicht störend.EXAMPLE 1 27 kg of sublemate are dissolved in 5o l of water with the addition of 1 kg of table salt, 12 to 151 acetone are added and the mixture is poured, with stirring, into 5o l of a four-fold normal sodium hydroxide solution heated to 30 to 40 °. The precipitated mercury oxide dissolves again immediately, and a completely clear solution is obtained, which is immediately mixed with so much dilute hydrochloric acid that a very little precipitate of the poorly soluble hydrochloric acid salt is precipitated. This is filtered off and an approximately 25 percent stable solution of the base is obtained, which also only contains common salt. Hydrochloric acid precipitates from it the hydrochloric acid salt, soda lye does not drop mercury oxide; causes there- after a short time. T> alymerisation., Am- monsulfiide -depends black. Mercury sulfide. Heat up °. go. his «ioon also effects Polymerization. Eiale even more concentration tration must be in a vacuum at a lower temperature temperature can be made. Example 13.57 kg (- / 2o moles) of mercury chloride are added with 5.8 lzg of sodium chloride dissolved in water. To 1 6,661 North Sodium hydroxide solution (1/10 mol.) is added to acetone and .pour the Quicksilver solution added. Unless completely clear, it is filtered. As a result of the high, that of the sublimate The bactericidal and fungicidal action of the base, which is several times greater, and its comparative insensitivity to metals, can be used for a variety of purposes in disinfection and fungus control. The salt content is not a problem.
