Description
Patentiert im Deutschen Reiche vom 10. Oktober 1913 ab. Längste Dauer: 25.JuIi 1927.Patented in the German Empire on October 10, 1913. Longest duration: July 25, 1927.
Bei dem Verfahren des Patents 272337 werden Fette und Öle durch Halogen wasserst offsäuren unter direkter Bildung von Glycerinhalogenhydrinen gespalten, wobei als Nebenprodukte Oxyfettsäureester gebildet werden. Da nach dem Prinzip von Le Chatelier chemische Reaktionen, insbesondere solche, bei denen gasförmige Komponenten verbraucht werden, durch Erhöhung des Druckes beschleunigt, beziehungsweise oft überhaupt erst ermöglicht werden, wurde seinerzeit die Umsetzung zwischen den Glyceriden und den Halogenwasserstoffsäuren nur unter erhöhtem Druck ausgeführt und die Anwendung von Druck auch als kennzeichnende Maßnahme im Patentanspruch besonders hervorgehoben. Es hat sich nun überraschenderweise ergeben, daß diese Reaktion auch ohne Überdruck glatt und bei genügender Einwirkungsdauer praktisch quantitativ verläuft. Es ist auch nicht nötig, die Temperatur bei der Reaktion höher zu halten, um den fehlenden Druck dadurch zu ersetzen. Durch das Arbeiten bei normalem Druck werden wesentliche Vorteile erzielt; es wird nicht nur das Druckmittel erspart, sondern auch die Apparatur wird vereinfacht und verbilligt, und die Durchführung des Verfahrens wird absolut gefahrlos. In the process of patent 272337, fats and oils are hydrogenated by halogen cleaved with direct formation of glycerol halohydrins, with as by-products Oxy fatty acid esters are formed. Since, according to the principle of Le Chatelier, chemical reactions, especially those in which gaseous components are consumed, accelerated by increasing the pressure, or are often made possible in the first place, was the implementation at the time between the glycerides and the hydrohalic acids carried out only under increased pressure and the application of Printing also highlighted as a characterizing measure in the patent claim. It has now been found, surprisingly, that this reaction can take place even without excess pressure runs smoothly and practically quantitatively with sufficient exposure time. It is it is also not necessary to keep the temperature higher during the reaction in order to avoid the missing Replace pressure with it. Working at normal pressure becomes essential Benefits achieved; it not only saves the pressure medium, but also the apparatus is simplified and cheaper, and the implementation of the procedure becomes absolutely safe.
Die Ausführung des Verfahrens geschieht in der gleichen Weise, in der gleichen Apparatur und auch unter Anwendung der gleichen Mengenverhältnisse wie bei dem Verfahren nach dem Hauptpatent. Es wird nur entsprechend länger die Einwirkung vorgenommen.The procedure is carried out in the same way, in the same apparatus and also using the same proportions as in the method according to the main patent. The effect is only carried out correspondingly longer.
