Description
Verfahren zur Herstellung von Dispersionen Bekanntlich gelten als wirksamste Peptisationsmittel für zahlreiche Emulsionen wie auch gewisse Suspensionen die Galle und die gallensauren Salze.Process for the preparation of dispersions are known to apply as most effective peptizers for numerous emulsions as well as certain suspensions the bile and the bile salts.
Es hat sich nun gezeigt, daß die besonders in den Knorpelsubstanzen wie im Tracheal- -knorpel des Rindes sowie der Nasenscheidewand des Schweines und. ihm Urin des Menschen usw. vorkommende Chondroitinschwefelsäure C18 H27 N SOj7 und ihre Salze die Peptisationswirkung der Galle und der gallensauren Salze ganz besonders in Hinsicht auf die Stabilisierung von Suspensionen weitaus übertreffen. In Hinsicht auf die Peptisation und Stabilisierung von Emulsionen ist die Chondroitinschwefelsäure und deren Salze den gallensauren Salzen mindestens ebenbürtig. It has now been shown that the particularly in the cartilage substances as in the tracheal cartilage of the cattle and the nasal septum of the pig and. human urine etc. occurring chondroitin sulfuric acid C18 H27 N SOj7 and Their salts have the peptizing effect of the bile and the bile acid salts in particular far surpass them in terms of stabilizing suspensions. In terms of Chondroitin sulfuric acid is responsible for the peptization and stabilization of emulsions and their salts are at least equal to the bile salts.
Wenn man zu je IOO ccm einer hinreichend feinen Calciumoxalatsuspension (8 g Calciumoxalat pro Liter) einmal nichts hinzufügt, das andere Mal je 1 ccm einer wäßrigen Lösung von o, 250/oigem chondroitinschwefelsaurem Natrium bzw. einer 0,25 Obigen Lösung von Natriumcholat hinzufügt, so zeigte sich, daß die Flüssigkeit in dem Zylinder, welcher nur Calciumoxalatsuspension enthielt, bereits nach 15 Minuten völlig geklärt war. If you add a sufficiently fine calcium oxalate suspension to every 100 ccm (8 g calcium oxalate per liter) once does not add anything, the other time 1 ccm each aqueous solution of 0.25% sodium chondroitin sulfuric acid or a 0.25 Adding the above solution of sodium cholate, it was found that the liquid in the cylinder, which only contained calcium oxalate suspension, after 15 minutes was completely resolved.
Die Suspension in dem Natriumcholat enthaltenden Zylinder war bereits nach I Stunde in erheblichem Maße geklärt, während die Suspension, welche chondroitinschwefelsaures Natrium enthielt, noch nach etlichen Stunden völlig milchig war.The suspension in the cylinder containing sodium cholate was already after 1 hour cleared to a considerable extent, while the suspension, which is chondroitin sulfuric acid Contained sodium, was completely milky even after several hours.
Dieselben Beobachtungen zeigten sich auch bei den verschiedensten anderen Suspensionen, z. B. wäßrigen Suspensionen von Bariumsulfat, Calciumcarbonat, von etlichen schwerlöslichen oder unlöslichen Alkaloidbasen, und ebenso waren verschiedenste Emulsionen, z. B. wäßrige Emulsionen von Butter, Petroleum, Öl, Schmalz, sehr stabil beim Zusatz geringer Mengen von Chondroitinschwefelsäure. The same observations were made in the most diverse other suspensions, e.g. B. aqueous suspensions of barium sulfate, calcium carbonate, of a number of sparingly soluble or insoluble alkaloid bases, and also were the most varied Emulsions e.g. B. aqueous emulsions of butter, petroleum, oil, lard, very stable when adding small amounts of chondroitin sulfuric acid.
