PATENTAMPATENTAM
Den Gegenstand vorliegender Erfindung bildet ein Verfahren zur Darstellung eines Doppelsalzes aus milchsaurem und salicylsaurem Natron. Dieses Verfahren besteht in Folgendem: 1000 g Salicylsäure werden in so viel heifsem Wasser gelöst, dafs eine möglichst concentrirte Lösung entsteht. Hierzu setzt man Milchsäure in einer Menge, welche je nach dem gewünschten Gehalt des anzufertigenden Präparates an milchsaurem Natron gröfser oder kleiner sein kann. Dieses Gemisch neutralisirt man mit kohlensaurem Natron oder Aetznatron. Es lassen sich dann weitere Mengen von Salicylsäure und Milchsäure in ' der Flüssigkeit auflösen, welche man wiederum neutralisirt. In gleicher Weise fährt man fort, bis man schliefslich eine concentrirte Lösung von salicyl- und milchsaurem Natron besitzt. Diese Lösung wird im Wasserbade abgedampft. Man erhält daraus ein trockenes Doppelsalz,· das salicylmilchsaure Natron, welches mit »Salactol« bezeichnet werden mag. Anstatt das Natron der Salicyl- und Milchsäurelösung zuzusetzen, kann man auch in eine Natronlösung Salicyl- und-Milchsäure eintragen. Natürlich können auch Gemische aus Lösungen des salicyl- und des milchsauren Natrons, welche bekanntlich fertig im Handel zu haben sind, zur Trockne abgedampft werden.The subject matter of the present invention is a method for the preparation of a Double salt made from lactic acid and salicylic acid baking soda. This procedure consists of the following: 1000 g of salicylic acid are dissolved in so much hot water that one is as concentrated as possible Solution emerges. To do this, lactic acid is used in an amount that depends on the desired Lactic acid soda content of the preparation to be made is greater or greater can be smaller. This mixture is neutralized with carbonate of soda or caustic soda. Further amounts of salicylic acid and lactic acid can then be dissolved in the liquid, which in turn is neutralized. In the same way one continues until one finally has a concentrated solution of salicylic and lactic acid soda. This solution is evaporated in a water bath. A dry double salt is obtained from it, salicyllactic acid Soda, which may be called "Salactol". Instead of the soda the Salicylic and lactic acid solutions can also be added to a soda solution of salicylic and lactic acid enter. Of course, mixtures of solutions of the salicylic and des lactic acid soda, which is known to be readily available in stores, is evaporated to dryness will.
Dafs auf solche Weise ein Doppelsalz und kein blofses mechanisches Gemenge entsteht, geht aus Folgendem hervor:That in this way a double salt and not a mere mechanical mixture is produced, emerges from the following:
Aus einer Lösung der gemischten Salze (salicylsaures und milchsaures Natron) in 5oprocentigem Alkohol krystallisirten beim langsamen Verdunsten kreisförmige Gruppirungen von langen Nädelchen aus, die sich nach möglichstem Entfernen der Mutterlauge als aus beiden Componenten, dem milch- und salicylsauren Natron, bestehend erwiesen. Diese Nädelchen waren auch beim mikroskopischen Betrachten als einheitliche Krystallbildungen zu erkennen, denen keine anderweitigen Krystallformationen beigemischt waren. Aus Obigem mufs demnach gefolgert werden, dafs diese Krystalle als Doppelsalz und nicht als mechanisches Gemenge des milch- und salicylsauren Natrons aufzufassen sind. Zur Bestätigung diente die quantitative Bestimmung, die ein bestimmtes moleculares Verhältnifs zwischen den Componenten, dem milch- und salicylsauren Natron, nachwies. Danach bestanden die Nädelchen aus 2 MoIecülen salicylsaurem Natron und 1 Molecül milchsaurem Natron.From a solution of the mixed salts (salicylic acid and lactic acid soda) in 5% Alcohol crystallized, on slow evaporation, in circular groups of long ones Small needles that, after removing the mother liquor as much as possible, turn out to be from both components, the lactic and salicylic acid soda, proven to exist. These little needles were even when viewed microscopically, they can be recognized as uniform crystalline formations no other crystal formations were admixed. From the above it must therefore It can be concluded that these crystals are a double salt and not a mechanical mixture of lactic and salicylic acid sodium are to be understood. The quantitative was used for confirmation Determination that a certain molecular ratio between the components, the lactic and salicylic acid baking soda. The needles then consisted of 2 molecules salicylic acid baking soda and 1 mol of lactic acid baking soda.
Ein derartiges Doppelsalz hat alle Eigenschaften des salicyl- und des milchsauren Natrons, nur ist es nicht mehr hygroskopisch. Dafs dies thatsächlich der Fall ist, ist in der folgenden Weise nachgewiesen.Such a double salt has all the properties of salicylic and lactic acid Natrons, only it's no longer hygroscopic. That this is actually the case is shown in the following way.
Die eine Schale einer Waage wurde mit trockenem salicyl-milchsauren Natron beschüttet, .eben dem neuen Doppelsalz, die andere mit milchsaurem Natron. Beide Stoffe waren in trockener Form. Schon nach kurzer Zeit begann die mit dem milchsauren Natron beschüttete der beiden vorher mittelst Gewichte ausbalancirten Schalen zu sinken.One of the bowls of a balance was poured with dry salicylic lactic acid sodium bicarbonate, next to the new double salt, the other with lactic acid baking soda. Both fabrics were in dry form. After a short time, the lactic acid soda poured in began of the two bowls previously balanced by weights.
