Patentiert im Deutschen Reiche vom 13. September 1911 ab.Patented in the German Empire on September 13, 1911 .
Die Fett und Öl verarbeitenden Industrien haben sehr oft große Unanehmlichkeiten und Störungen in ihren Betrieben, hervorgerufen durch unfreiwillige und zum Teil sehr hartnackige Emulsionsbildung ihrer verarbeiteten Fette oder Fettsäuren, mit· den zur Reinigung oder zu anderen Zwecken angewandten wäßrigen Flüssigkeiten. In gleicher Weise halten z.B. gewisse Fettsäuren hartnäckig bei derThe fat and oil processing industries very often have great inconveniences and problems Disturbances in their operations, caused by involuntary and sometimes very persistent ones Emulsification of your processed fats or fatty acids with the cleaning agents or aqueous liquids used for other purposes. Hold in the same way e.g. certain fatty acids stubborn in the

' . ergeben haben, sind an diesen Vorgängen häufig die Eiweiß- bzw. Zellhäute schuld,-welche in jedem pflanzlichen bzw. tierischen Fette oder Öle mehr oder weniger enthalten sind. Die Fettmoleküle, besonders die der tierischen öle, wie z. B. die Trane, werden umspannt von einer äußerst dünnen Zellhaut.'. have shown, the protein or cell membranes are often to blame for these processes contained more or less in any vegetable or animal fats or oils are. The fat molecules, especially those of animal oils, such as. B. the Trane encompassed by an extremely thin cell membrane.
Diese Zellgewebe verursachen gleichfalls die unangenehme Emulsionsbildung. Beweis für die Richtigkeit dieser Auffassung ist der Umstand, daß sich dieEmulsionen lösen, sobald dieselben mit konzentrierter Schwefelsäure behandelt und auf diese Wreise die Zellhäute zum Verkohlen gebracht werden. Dieses Verfahren läßt sich natürlich mit Rücksicht auf die Farbe der Fettsäuren nur in den seltensten Fällen anwenden. Besonders dort, wo es sich darum handelt, aus den Fettsäuren eingeschlossenes Glycerinwasser zur Abscheidung zu bringen, kann diese Methode nicht benutzt werden. Auf Grund obiger Beobachtung ist es nun gelungen, in dem Formaldehyd und seinen polymeren Modifikationen ein Mittel zu finden, welches die Eiweißbzw. Zellgewebe rasch zum Coagulieren bringt, ohne daß die Fettstoffe bzw. das Glycerin schädlich beeinflußt werden. Je nach dem Eiweißgehalt der Fette ist eine mehr oder weniger große Menge von Formaldehyd anzuwenden. In der Regel genügt selbst bei hartnäckigsten Emulsionen ein Zusatz von 0,3 Prozent Formaldehyd, um eine rasche und glatte Trennung zu bewirken.These cell tissues also cause the unpleasant formation of emulsions. Proof of the correctness of this view is the fact that solving The emulsions when they are treated with concentrated sulfuric acid, and r in this w ay the cell membranes are made to charring. Of course, this method can only be used in the rarest of cases, taking into account the color of the fatty acids. This method cannot be used, especially where it is a question of separating glycerine water from the fatty acids. On the basis of the above observation, it has now been possible to find a means in formaldehyde and its polymeric modifications which removes the protein and Brings cell tissue to coagulate quickly without damaging the fatty substances or glycerine. Depending on the protein content of the fats, a more or less large amount of formaldehyde must be used. As a rule, even with the most stubborn emulsions, an addition of 0.3 percent formaldehyde is sufficient to achieve a quick and smooth separation.
