Description

Verfahren zur Trennung von Lipoidgemischen Es ist bekannt, daß in organischen Lösungsmitteln kolloid verteilte Stoffe bei der Dialyse durch solche Membranen, die in wä.ßrigen Lösungsmitteln verteilte Kolloide zurückhalten, ungehindert durchgehen. Daher sind bekanntlich zur Reinigung von Organosolen durch Dialyse ganz andere Membranen erforderlich als für die Dialyse von Hydrosolen.Process for the separation of lipoid mixtures It is known that in organic solvents colloidly distributed substances during dialysis by such Membranes that hold back colloids distributed in aqueous solvents, unhindered go through. Therefore, it is known to purify organosols by dialysis all over different membranes are required than for dialysis of hydrosols.

Es hat sich nun gezeigt, daß für die Dialyse in wäßrigen organischen Lösungsmitteln wieder ganz andere Durchwanderungsgesetze gelten, und daß man solche Stoffe, die .in wäßrigen organischen Lösungsmitteln bei verschiedenem Wassergehalt der Lösungsmittel einen verschiedenen Dispersitätsgrad zeigen, durch Dialyse oder Ultrafiltration in wäßrigen organischen Lösungsmitteln von geeignetemWassergehalt voneinander trennen kann.It has now been shown that for dialysis in aqueous organic Solvents completely different laws of migration apply, and that such Substances that .in aqueous organic solvents with different water content the solvents show a different degree of dispersion, by dialysis or Ultrafiltration in aqueous organic solvents of suitable water content can separate from each other.

Beispiel i Zu einer klaren absolut alkoholischen Lösung (iooccm) eines Gemisches von Kephalin und Lecithin werden 6 ccm Wasser tropfenweise zugesetzt, so daß die vorher optisch reine Lösung beim Schütteln das Freundlich-Dieselhorstsche Schlierenphänomen zeigt. Diese wäßrige alkoholische Lösung wird nun durch ein in bekannter Weise hergestelltes kolloidales Ultrafilter durchgesaugt. Das Filtrat läßt sich durchAceton nicht mehr ausfällen und läßt auch sonst keinen Kephalingehalt mehr erkennen, enthält dagegen das gesamte Lecithin der Ausgangsmischung.Example i For a clear absolutely alcoholic solution (iooccm) one Mixtures of cephalin and lecithin are added dropwise to 6 ccm of water, so that the previously optically pure solution becomes the Freundlich-Dieselhorstsche when shaken Shows streak phenomenon. This aqueous alcoholic solution is now through an in known way produced colloidal ultrafilter sucked through. The filtrate can no longer be precipitated by acetone and does not leave any other cephalin content recognize more, however, contains all of the lecithin of the starting mixture.

Beispiel a Eine Lösung von je o,2 g Salicvlsä;ire und Stearinsäure in iooccm 7oprozentigem Alkohol wird meine in bekannter Weise hergestellte; kolloide Membran von passender Form eingebracht und gegen 70°/" Alkohol dialysiert. Nach mehrfachem Wechsel des Alkohols in der Außenphase bleibt ein Dialyserückstand in dem Säckchen, der keine Salicylsäurereaktion mehr liefert, dagegen die gesamte Stearinsäure der Ausgangslösung enthält.Example a A solution of 0.2 g each of salicvic acid and stearic acid mine is prepared in a known manner in 100% alcohol. colloids Membrane of suitable shape introduced and dialyzed against 70 ° / "alcohol. After If the alcohol is changed several times in the outer phase, a dialysis residue remains in the sachet, which no longer produces a salicylic acid reaction, has all of the stearic acid the starting solution contains.

Beispiel 3 Die Lösung eines Rohextraktes von ausgeschälten Follikeln aus Eierstöcken in 75"/" Alkohol wird durch ein 5 % Kollodiumultrafilter hindurchgesaugt. Die Ausgangslösung enthielt in qo g Trockensubstanz q.oo Mäusebrunsteinheiten, das Ultrafiltrat enthält in ,einem Gesamttrockenrückstand von 2 mg i oo Mäusebrunsteinheiten.Example 3 The solution of a crude extract from peeled follicles from ovaries in 75 "/" alcohol is sucked through a 5% collodion ultrafilter. The starting solution contained q, o g of dry matter, mouse oestrus units, that The ultrafiltrate contains in, a total dry residue of 2 mg 10 oo mouse oestrus units.

Beispiel q.Example q.

Dialysiert man die Lösung eines Kephalin-Cholesterin-Gemisches inwasserfreiem Tetrachlorkohlenstoff durch eine hinreichend dichte V Kolladiummembran, so erhält man in der Außenflüssigkeit Kephalin (gemessen am Kephalinphosphor) und Cholesterin in gleichem Verhältnis, wie es in der Innenflüssigkeit benutzt wurde. Sättigt man die Tetrachlorkohlenstofflösung des Gemisches mit Wasser,- so dialysiert nur noch das Cholesterin, während das Kephalin (vgl. hierzu auch H.Dieselhorstund H.Freundlioh, Internat. Zeitschr. .f. physik.-chem. Biologie, Bd.3, igiö, S.59) in einen anisotrop kolloiden Dispersitätszustand übergegangen ist und von der Membran zurückgehalten wird.If the solution of a cephalin-cholesterol mixture in anhydrous carbon tetrachloride is dialyzed through a sufficiently dense V colladium membrane, cephalin (measured by the cephalin phosphorus) and cholesterol are obtained in the outer fluid in the same ratio as was used in the inner fluid. If the carbon tetrachloride solution of the mixture is saturated with water, only the cholesterol is dialyzed, while the cephalin (cf. also H.Dieselhorst and H.Freundlioh, Internat. Zeitschr. .F. Physik.-chem. Biologie, Vol.3, igiö, p.59) has passed into an anisotropic colloidal state of dispersion and is retained by the membrane.
