Abstract

Aqueous and organic solutions (ether, benzene, chloroform, pentane) of lactic acid have been submitted to gas chromatography. Besides of the peak of the monomeric compound four other peaks have been detected corresponding to condensation products. The percentage of the different components depended on the concentration of the solutions and the kind of solvent.

Zusammenfassung

Wäßrige und organische Lösungen (Äther, Benzol, Chloroform, Pentan) von Milchsäure wurden gas-chromatographisch untersucht. Dabei wurden neben dem Peak der monomeren Verbindung noch 4 weitere Peaks von Kondensationsprodukten gefunden. Der Anteil der einzelnen Komponenten am Gesamtgehalt war je nach Konzentration der untersuchten Lösung und Art des Lösungsmittels verschieden (Tabelle).
