Description
Verfahren zur Darstellung von methansulfonsaurem Caleium. Es ist bekannt, dass die Alkalisalze der aliphatischen Sulfonsäuren, zum Beispiel von Methan-, Äthan- und Benzylsulf onsäure, sich leicht gewinnen lassen durch Einwir kung von Alkalisulfiten auf Ralogenalkyle, zum Beispiel auf Äthylbromid oder Benzyl- chlorid,
oder durch Einwirkung auf alkyl- schwefelsaure Alkalisalze. Gemäss dieser Re aktion konnte man das technisch wichtigere Calciumsalz der Methansulfonsäure nicht her stellen; Methylhaloid oder methylschwef el- saures Alkali wirken auf Calciumsulfit nicht ein.
Das in der Literatur beschriebene me- thansulfonsaure Calcium wird durch Neu tralisation der mehr oder weniger reinen Säure mit Kalkmilch hergestellt.
Das methansulfonsaure Calcium lässt sich nun aber technisch leicht herstellen durch Behandeln des methansulfonsauren Ammo niums mit Kalkmilch; das methansulfon- saure Ammonium war indessen bisher nicht in '-3chnisch befriedigender Weise zugä-ng- lieh gemacht.
Es wurde gefunden, dass dieses Salz leicht gewonnen werden kann durch Ein wirkung eines Methylesters der Schwefel säure, zum Beispiel von Dimethylsulfat oder methylschwefelsaurem Alkali, auf Ammo- niumsulfit. Dies zwar nicht vorauszusehen, weil Ammoniumsulfit in verschiedenen Re aktionen sich träger zeigt als Natriumsulfit, umsomehr, als erforderlich ist, in der gälte zix arbeiten, um einer Methylierung des Ammoniumradikals vorzubeugen.
Die Reaktion des Dimethylsulfates ver läuft in zwei Phasen; es reagiert zuerst unter Bildung von einem Molekül methan- sulf onsaurem Ammonium und methylschwef el- saurem Ammonium, welches in der Kälte nicht weiter reagiert. Die zweite Phase in der Wärme führt von methylschwefelsaurein Ammonium zu Ammoniumsulfat unter Bil dung eines zweiten Moleküls von methan- salfonsaurem Ammonium.
Es ist einleuch tend, dass man auf die Anwendung des Di- methylsulfates verzichten und sich auf die zweite Phase beschränken kann, indem man von dem technisch leicht herstellbaren me- thylschwefelsauren Ammonium ausgeht und von Anfang an in der Wärme arbeitet.
Neben dem Ammoniumethansulfonat enthält das Reaktionsprodukt nur überschüssiges Ammoniumsulfit und das gebildete Ammo- niumsulfat; beide Körper lassen sich in der nachfolgenden Operation mit Kalkmilch leicht beseitigen, und man erhält so eine reine, von organischen Beimischungen freie Lösung von methansulfonsaurem Calcium. Diese Lösung lässt sich für die meisten Zwecke direkt verwenden. Beim Eindampfen zur Trockne liefert sie das reine Salz.
<I>Beispiel:</I> 126 Teile reines Dimethylsulfat oder eine entsprechende Menge technischer Ware werden langsam bei 10 C in 600 Raum teile einer 26 9igen Lösung von Ammonium sulfit eingetragen; nachdem sich das Di- methylsulfat vollständig gelöst hat, versetzt man noch mit 150 Teilen einer 50 öigen kristallinischen Paste von Ammonitunsu1fit und erhitzt einige Stunden auf dem Wasser bad.
Man verdünnt auf das dreifache Vo lumen, zersetzt heiss die kleine Menge von überschüssigem Sulft mit Schwefelsäure, setzt die berechnete Menge Kalkmilch zu und kocht das Ammoniak weg. Ein allfälli ger Überschuss von Kalkmilch wird durch vorsichtigen Zusatz von Schwefelsäure be seitigt und das Reaktionsprodukt vollends mit Kalkmilch neutralisiert. Die nun von Gips abfiltrierte Lösung enthä, reines Cal ciumsalz der Methansulfonsäure und wird als solche weiter verarbeitet, oder zur Trockne verdampft.
Die #.\-usbcute ist quantitativ.
Process for the preparation of methanesulfonic acid Caleium. It is known that the alkali salts of aliphatic sulfonic acids, for example of methane, ethane and benzylsulfonic acid, can easily be obtained by the action of alkali sulfites on ralogen alkyls, for example on ethyl bromide or benzyl chloride,
or by acting on alkali metal salts of alkyl sulfuric acid. According to this reaction, the technically more important calcium salt of methanesulfonic acid could not be produced; Methyl halide or methyl sulfuric acid alkali have no effect on calcium sulfite.
The methanesulfonic acid calcium described in the literature is produced by neutralizing the more or less pure acid with milk of lime.
The methanesulfonic acid calcium can now be easily produced technically by treating the methanesulfonic acid ammonium with milk of lime; methanesulfonic acid ammonium, however, has not yet been made accessible in a technically satisfactory manner.
It has been found that this salt can easily be obtained by the action of a methyl ester of sulfuric acid, for example of dimethyl sulfate or alkali methyl sulfate, on ammonium sulfite. This cannot be foreseen, because ammonium sulphite is more sluggish than sodium sulphite in various reactions, all the more so as it is necessary to work in the cold to prevent methylation of the ammonium radical.
The reaction of the dimethyl sulfate ver runs in two phases; it first reacts to form a molecule of methanesulfonate ammonium and methylsulfonate ammonium, which does not react further in the cold. The second phase in the heat leads from methylsulfuric acid ammonium to ammonium sulfate with the formation of a second molecule of methanesulfonic acid ammonium.
It is evident that dimethyl sulfate can be dispensed with and restricted to the second phase by starting from the technically easy to manufacture methylsulfuric acid ammonium and working with heat from the start.
In addition to the ammonium ethanesulfonate, the reaction product only contains excess ammonium sulfite and the ammonium sulfate formed; Both bodies can easily be removed in the subsequent operation with milk of lime, and a pure solution of methanesulfonic acid calcium, free of organic admixtures, is obtained. This solution can be used directly for most purposes. When evaporated to dryness, it delivers the pure salt.
<I> Example: </I> 126 parts of pure dimethyl sulfate or a corresponding amount of technical goods are slowly introduced at 10 C into 600 parts of a 26 9 solution of ammonium sulfite; After the dimethyl sulfate has completely dissolved, 150 parts of a 50% crystalline ammonite sulphate paste are added and the mixture is heated on the water bath for a few hours.
It is diluted to three times the volume, the small amount of excess sulphite is decomposed while hot with sulfuric acid, the calculated amount of milk of lime is added and the ammonia is boiled away. Any excess milk of lime is eliminated by carefully adding sulfuric acid and the reaction product is completely neutralized with milk of lime. The solution now filtered from gypsum contains pure calcium salt of methanesulfonic acid and is further processed as such or evaporated to dryness.
