sind. Selbst wenn man grosse Mengen des Spaltmaterials anwendet, gewinnt man Fettsäuren, welche erheblich heller gefärbt sind als die unter Benutzung von Spaltern aus unbehandelten Fetten oder Fettsäuren gewonnenen. Man hat gleichzeitig den Vorteil, die Spaltung erheblich abzukürzen, weil man mit wesentlich mehr Spaltmaterial (ungefähr doppelt soviel) als bisher arbeiten kann. Die gewonnenen Fettsäuren sind auch in diesem Falle ausserordentlich hell bzw. ebenso oder fast ebenso gefärbt wie das Ausgangsmaterial.
Auch das Glyzerin, welches man bei Anwendung der aus reduzierten Fettsäuren oder Fetten hergestellten sulfoaromatischen Spalter gewinnt, ist wesentlich klarer und heller, als das bei Anwendung der aus gewöhnlichen Fettsäuren erzeugten sulfoaromatischen Spalter gewonnenen. Die Reinigung des gewonnenen Glyzerins erfolgt daher in wesentlich einfacherer und billigerer Weise.
Die Herstellung des Spalters geschieht z. B. in folgender Weise : 100 kg Rizinusöl werden z. B. nach dem Paalschen Verfahren reduziert. Das Reduktionsprodukt wird mit 100 kg Naphtalin zu einem feinen Pulver vermahlen und das Gemisch allmählich unter Rühren in 400 log Schwefelsäure von 66 eingetragen. Die Temperatur soll während dieses Prozesses nicht über etwa 200 steigen. Das Rühren wird solange fortgesetzt, bis eine gleichmässige Lösung entstanden ist ; dann wird die ganze Masse in 800 1 Wasser von Zimmertemperatur eingetragen und gut durchgerührt.
Es bilden sich alsbald zwei Schichten, von welchen die untere, die eine etwa 33% ige Schwefel- säure darstellt, aus dem Verfahren entfernt wird. Die obere Schicht wird eventuell durch
Filtration von unwirksamen Bestandteilen befreit und stellt dann den Spalter dar.
Die Spaltung selbst erfolgt z. B. in folgender Weise : 1000 k. g Palmkeröl werden mit 300 kg
Wasser und 2 kg des oben beschriebenen Spalters gemischt und in das Gemenge getrockneter
Dampf eingeleitet. Nach 6 bis 8 Stunden wird der Dampf abgestellt und die Spaltung ist technisch vollendet. Man überlässt jetzt das Gemenge der Ruhe, eventuell unter Hinzufügung geringer
EMI2.1
Emulsion zu trennen. Es bilden sich zwei Schichten mit klarer spiegelnder Trennungsfläche.
Die untere stellt das Glyzerinwasser dar, welches nach Entfernung der Schwefelsäure nach be- kannter Methode ohneweiters konzentriert werden kann, die obere Schicht besteht aus den abgespaltenen Fettsäuren des Fettes oder Öles.

are. Even when using large amounts of the fission material, fatty acids are obtained which are much lighter in color than those obtained from untreated fats or fatty acids using crackers. At the same time, you have the advantage of shortening the splitting process considerably, because you can work with considerably more splitting material (about twice as much) than before. In this case, too, the fatty acids obtained are extremely light-colored or have the same or almost the same color as the starting material.
The glycerine obtained by using the sulfoaromatic breakers made from reduced fatty acids or fats is much clearer and lighter than that obtained when using the sulfoaromatic breakers made from common fatty acids. The glycerine obtained is therefore cleaned in a much simpler and cheaper way.
The production of the splitter is done, for. B. in the following way: 100 kg of castor oil z. B. reduced by the Paal method. The reduction product is ground to a fine powder with 100 kg of naphthalene and the mixture is gradually added to 400 logs of 666 sulfuric acid with stirring. The temperature should not rise above about 200 during this process. Stirring is continued until a uniform solution has formed; then the whole mass is introduced into 800 l of water at room temperature and stirred well.
Two layers soon form, of which the lower one, which is about 33% sulfuric acid, is removed from the process. The top layer will eventually go through
Filtration freed from ineffective components and then represents the splitter.
The split itself takes place z. B. in the following way: 1000 k. g of palm kerel are with 300 kg
Water and 2 kg of the breaker described above are mixed and dried in the mixture
Steam initiated. After 6 to 8 hours, the steam is switched off and the cleavage is technically complete. The mixture is now left to rest, possibly with the addition of less
EMI2.1
Separate emulsion. Two layers are formed with a clear, reflective separation surface.
The lower layer represents the glycerine water, which after removal of the sulfuric acid can be concentrated without further ado using a known method, the upper layer consists of the split off fatty acids of the fat or oil.
