Description
Verfahren zur Zersetzung der bei der Fettspaltung sich bildenden Emulsionen Die haltbaren Emulsionen, die sich bei der Spaltung der Fette mittels hochmolekularer Sulfonsäuren bilden, müssen beider Trennung des Glycerinwassers von den Fettsäuren einer Zersetzung unterworfen werden. Durch das gewöhnlich angewendete Verfahren - Zusatz einer ziemlichen Menge von Schwefelsäure zur Emulsionsmischung am Ende des Spaltungsprozesses - wird die Emulsion zwar leicht zersetzt, doch wird dabei eine recht große Menge der Sulfonsäuren aus der wässerigen Lösung ausgeschieden (ausgesalzen) und durch die Fettsäuren gelöst, was deren Farbe verschlechtert und ihre .Reinigung, wie die des Glycerinwassers, kompliziert.Process for the decomposition of the emulsions formed during fat splitting The long-lasting emulsions that result in the breakdown of fats by means of high molecular weight Forming sulfonic acids must both separate the glycerol water from the fatty acids be subjected to decomposition. By the usual procedure - Adding a fair amount of sulfuric acid to the emulsion mixture at the end the splitting process - the emulsion is easily broken down, but it is quite a large amount of the sulfonic acids were excreted from the aqueous solution (salted out) and dissolved by the fatty acids, which worsens their color and Their cleaning, like that of glycerine water, is complicated.
Es wurde nun festgestellt, daß die permanenten Emulsionen, welche bei der Fettspaltung mittels hochmolekularer Sulfonsäuren sich bilden, durch Zusatz einer kleinen Menge von Calciumsulfat leicht und schnell zerstört werden. Dabei wird die in dem Glycerinwasser sich befindende .freie Schwefelsäure nicht neutralisiert und verhindert die Bildung der fettsauren Calciumsalze, die Sulfonsäuren jedoch bilden die entsprechenden Calciumsulfonate und werden zusammen mit dem Glycerinwasser von den Fettsäuren getrennt. Je nach der Menge der Sulfonsäuren, die man zur Spaltung der Fette verwendet, wird der Emulsion o, i bis o, 5 % Caleiumsulfat, d. h. ungefähr ein Viertel der Gewichtsmenge der Sulfonsäuren, zugesetzt.It has now been found that the permanent emulsions which are formed during fat cleavage by means of high-molecular sulfonic acids, through addition a small amount of calcium sulfate can be easily and quickly destroyed. Included the .frei sulfuric acid in the glycerine water is not neutralized and prevents the formation of the fatty acid calcium salts, but the sulfonic acids form the corresponding calcium sulfonates and are used together with the glycerol water separated from the fatty acids. Depending on the amount of sulfonic acids that are used for cleavage the fats used, the emulsion o, i to o, 5% calcium sulfate, d. H. approximately a quarter of the weight of the sulfonic acids, added.
Das abgetrennte rohe Glycerinwasser wird in der üblichen Weise gereinigt und konzentriert. Die ungelösten Calciumsulfonate können dabei leicht von dem Glycerinwasser getrennt und wieder zur Spaltung der Fette bei Gegenwart einer genügenden Menge von Schwefelsäure, bei deren Anwendung sich freie Sulfonsäuren bilden, angewendet werden.The separated raw glycerol water is purified in the usual way and focused. The undissolved calcium sulfonates can easily be removed from the glycerol water separated and again to split the fats in the presence of a sufficient amount of sulfuric acid, the application of which forms free sulfonic acids will.
