Description
Verfahren zur Gewinnung von Knochenfett und Leim aus Knochen. Die Sammelknochen, idie zur Herstellung von Leim und Gelatine benutzt werden sollen, enthalten außer der Knochen- und Leimsubstanz noch Fett und Wasser. Die Knochen werden infolgedessen zur Entfernung des Fettes mittels eines Lösungsmittels, Benzin, Trichloräthylen, Tetrachlorkohlensto:ff o. dgl., extrahiert. Dias Lösungsmittel greift aber nicht oder doch nur unvollkommen an, solange die Knochen noch naß sind; sie werden deshalb vor oder während der - Extraktion auf hohe Temperaturen :erhitzt, bei denen das Wasser schnell zur Verdampfung gelangt.Process for obtaining bone fat and glue from bones. the Collection bones to be used to make glue and gelatin, In addition to bone and glue, they also contain fat and water. The bones are therefore used to remove the fat using a solvent, gasoline, Trichlorethylene, carbon tetrachloride: ff or the like, extracted. Dias solvent but does not attack, or at least only imperfectly, as long as the bones are still wet; they are therefore - heated to high temperatures before or during the extraction, where the water evaporates quickly.
,Gerade die Anwendung der hohen Temperatur wirkt aber bei :Gegenwart von Wasser schädigend sauf die Beschaffenheit der Farbe des Knochenfettes und Leimes, auch mindernd auf .die Leimausbeute.However, it is precisely the application of the high temperature that has an effect on: the present from water damaging to the consistency of the color of the bone fat and glue, also reducing the glue yield.
Die in !den Knochen enthaltenen basischen Kalzium- und :Maanesiumverbdndungen wirken bei Gegenwart von Wasser bei einer Temperatur von etwa roo° C zersetzend auf die Cxlyzeri,de ein und erhöhen :deshalb,denGehalt an freien Fettsäuren bzw. an Kalkseifen in dein gewonnenen Knochenfett. Eine Erhöhung der freien Fettsäuren bedeutet aber Verlust an Glyzerin - ein Kalkstifengehalt verschlechtert id:ie Qualität ider aus dem Knochenfett gewonnenen Seife; -die Farbe des Knochenfettes wird durch die Behandlung bei der hohen Temperatur dunkler. Der aus den Knochen gewonnene Leim hat infolge der hohen Temperatur bei der Extraktion an Leimkraft verloren; aber auch ,die Ausbeute leidet, da bei Gegenwart von Wasser bei der hohen Temperatur Leimsubstanz in Lösung geht.The basic calcium and maanesium compounds contained in the bones have a decomposing effect in the presence of water at a temperature of around roo ° C on the Cxlyceri, de and increase: therefore, the content of free fatty acids or of lime soaps in your extracted bone fat. An increase in free fatty acids but means a loss of glycerine - a lime stick content deteriorates id: ie quality the soap made from bone fat; -the color of the bone fat will be through treatment at high temperature darker. The glue extracted from the bones has lost its glue strength due to the high temperature during extraction; but Also, the yield suffers because of the presence of water at the high temperature Glue substance goes into solution.
Es wurde nun festgestellt, daß diese Übelstände sich beseitigen lassen, wenn vor ider eigentlichen Extraktion ,eine Vorbehandlung mit Alkohol (Spir@ittrs) erfolgt, .der auch geringe Mengen von Benzol o. dgl. zugefügt sein können.It has now been established that these evils can be eliminated, if before the actual extraction, a pretreatment with alcohol (Spir @ ittrs) takes place, .the small amounts of benzene o. The like. May be added.
Die Knochen werden zu diesem Behufe .in einem geeigneten Extraktionsapparat einer Vorextraktion durch Alkohol (Spiritus) unterworfen. Dadurch wird bei verhältnismäßig niedriger Temperatur das Wasser aus den Knochen :entfernt; etwa in Iden Knochen schon vorhandene freie Fettsäure wird gelöst.For this purpose the bones are removed in a suitable extraction apparatus subjected to pre-extraction by alcohol (spirit). This is at proportionate low temperature the water from the bones: removed; about in Iden bones any free fatty acid that is already present is dissolved.
Die alkoholische Lösung ward destilliert und der verdünnte Alkohol :rektifiziert; ebenso wird ider in den Knochen noch vorhandene Anteil von Alkohol vor der Extraktion abgetrieben.The alcoholic solution was distilled and the diluted alcohol : rectified; Likewise, the proportion of alcohol still present in the bones becomes aborted prior to extraction.
' Dann =beginnt :die eigentliche Extraktion mit dem Fettlösungsmittel. Diese geht nun bei verhältnismäßig niedriger Temperatur glatt und schnell vonstatten. Dia kein Wasser mehr vorhanden ist, so ergibt sich ein fast neutrales kallkseifenfrenes, in Farbe helleres und .deshalb wertvolleres Fett.'Then = begins: the actual extraction with the fat solvent. This now takes place smoothly and quickly at a relatively low temperature. When there is no more water, the result is an almost neutral soap-free, Fat lighter in color and therefore more valuable.
Die nachdem Abtreibendes Lösungsmittels verbleibenden Knochen ergeben, da sie bei der Extraktion sorgfältiger ;behandelt werden, einen in. Farbe und Beschaffenheit besseren Leim, aber auch eine höhere Ausbeute.The bones remaining after the solvent is aborted result in since they are treated more carefully during extraction, one in color and texture better glue, but also a higher yield.
Es ist Ballgemein bekannt, daß ein mit etwas Wasser verdünnter Alkohol freie Fettsäuren leicht löst, aber Triglyzeride nicht, so daß man Fettstoffe zur Extraktion von freien Fettsäuren mit mäßig verdünntem Alkohol behandeln kann. Es handelt sich aber bei vorliegendem Verfahren weniger um die Lösung und Abtrennung der bereits vorhandenen freien Fettsäuren, sondern vielmehr um eine geeignete Entwässerung des Ausgangsgutes zwecks Verhinderung von Übelständen, die durch die Gegenwart von Wasser im Gute bei der üb- lichen Art der Verarbeitung entstehen.It is generally known that an alcohol diluted with a little water easily dissolves free fatty acids, but not triglycerides, so that fatty substances can be treated with moderately diluted alcohol for the extraction of free fatty acids. In the present process, however, it is less a matter of dissolving and separating the free fatty acids that are already present, but rather of suitable dehydration of the starting material in order to prevent inconveniences caused by the presence of water in the material in the usual type of processing.
