JUL. ATHENSTÄDT in BAD ESSEN bei OSNABRÜCK. ..Verfahren zur Darstellung von essig-milchsaurer und essig-citronensaurer Thonerde. JUL. ATHENSTÄDT in BAD ESSEN near OSNABRÜCK. ..Process for the preparation of acetic-lactic and acetic-citric acid alumina.
Zusatz-Patent zu No. 9790 vom 21. November 1879.Patent addition to No. 9790 of November 21, 1879.
Patentirt im Deutschen Reiche vom 6. Januar 1880 ab. Längste Dauer: 20. November 1894.Patented in the German Empire on January 6, 1880. Longest duration: November 20, 1894.
Aendert man das im Patent No. 9790, beschriebene Verfahren der Bereitung essig -weinsaurer Thonerde so ab, dafs man anstatt der Weinsäure- oder Weinsäuren Thonerde - Lösung Milchsäure- oder Citronensäure-Lösung, oder auch milchsaure oder citronensäure Thonerde-Lösung anwendet, so ergeben sich Präparate, welche, je nach der verwendeten Säure, aus essigsaurer und milchsaurer, oder aus essigsaurer und citronensaurer Thonerde bestehen. Die quantitative chemische Zusammensetzung auch dieser Verbindungen ist, ebenso wie diejenige der essig-weinsauren Thonerde, nicht constant; die Essigsäure läfst sich aus ihrer Verbindung mit Thonerde durch jede der drei Säuren vollständig verdrängen.If this is changed in patent no. 9790, described Process of preparing vinegar-tartaric alumina so that instead of the Tartaric acid or tartaric acid clay solution Lactic acid or citric acid solution, or also uses lactic acid or citric acid clay solution, this results in preparations which, depending on the acid used, from acetic acid and lactic acid, or from acetic acid and citric alumina. The quantitative chemical composition too of these compounds, like that of the vinegar-tartaric clay, is not constant; acetic acid, from its combination with alumina, dissolves completely through any of the three acids push away.
Auf 5 Theile zweidrittel-essigsaurer Thonerde sind etwa 4 Theile Milchsäure von 1,20 spec. Gewicht oder 2 y2 Theile Citronensäure zur Auflösung erforderlich.For 5 parts of two-thirds of acetic acid alumina there are about 4 parts of lactic acid of 1.20 spec. Weight or 2 and 2 parts of citric acid required for dissolution.
Die als Ergebnisse des Verfahrens entstehenden beiden Präparate besitzen, ebenso wie die essigsaure-weinsaure Thonerde, eine gut antiseptische und mild adstringirende Wirkung. Die essigsaure - milchsaure Thonerde unterscheidet sich in ihrem chemischen Verhalten von den beiden anderen Verbindungen dadurch, dafs sie keine oder nur unvollständige Fällung des Albumins bewirkt; sie dürfte sich zur directen Wundbehandlung am geeignetsten erweisen. Beide Präparate bilden zerrieben ein weifses oder weifsliches Pulver von säuerlichem Geruch, und sind in demselben Verhältnifs wie die essigsaure-weinsaure Thonerde in Wasser leicht löslich.The two preparations resulting from the process, as well as the Acetic-tartaric clay, a good antiseptic and mild astringent effect. the acetic acid - lactic acid alumina differs in its chemical behavior from the two other compounds by the fact that they have no or only incomplete precipitation of the Albumin causes; it should prove to be most suitable for the direct treatment of wounds. Both preparations, when crushed, form a white or white powder with a sour odor, and are light in water in the same proportion as the acetic and tartaric alumina soluble.
