Description

Verfahren zur Neutralisation von Ölen und Fettkörpern. Gegenstand des vorliegenden Patentes bildet ein Verfahren, um öle und Fette, die einen Gehalt an freien Fettsäuren haben, zu entsäuern.Process for the neutralization of oils and fatty bodies. object of the present patent forms a method to produce oils and fats that have a content of free fatty acids have to deacidify.

Es ist bekannt, daß diese Entsäuerung mittels Alkalien in wässerigen Lösungen praktisch nicht durchführbar ist, da die entstehenden Seifen von den neutralisierten ölen und Fetten praktisch nicht zu trennen sind, da sie die öle ganz oder zum Teil emulgieren.It is known that this deacidification using alkalis in aqueous Solutions is practically not feasible because the resulting soaps are neutralized by the oils and fats can practically not be separated, since they contain the oils in whole or in part emulsify.

Man hat zu diesem Zwecke bereits vorgeschlagen, die zu neutralisierenden Fette in flüchtigen Lösungsmitteln, wie Kohlenwasserstoffen, Schwefelkohlenstoff u. dgl., aufzulösen und diesen Lösungen die Neutralisationsmittel, wie z. B. Natriumkarbonat, in Lösung oder in fester Form zuzusetzen.For this purpose it has already been suggested that those to be neutralized Fats in volatile solvents such as hydrocarbons, carbon disulfide and the like. To dissolve and these solutions the neutralizing agents, such as. B. Sodium Carbonate, to be added in solution or in solid form.

Aber auch diese Maßnahme führt nicht zu einem technisch brauchbaren Resultat. Setzt man die Neutralisationsmittel in Lösung zu, so bilden sich ebenfalls wieder Emulsionen, in die die ätherischen Lösungsmittel zum Teil ebenfalls hineingehen. Aber weiter zeigt sich als technisch schwer zu überwindender L beistand die Tatsache der Bildung eines sehr -nähen und kaum zu beseitigenden Schaumes. Der letztere fibelstand ist auch dann vorhanden, wenn die Neutralisarionsmittel, z. B. Natriumkarbonat, in trockener Form angewendet werden. Die bei der Reaktion entweichende Kohlensäure steigt in den zu neutralisierenden Flüssigkeiten auf und tritt an der Oberfläche als dicker Schaum in die Erscheinung. Der übelstand der Schaumbildung ist um so schwerwiegender, wenn man, wie dies bei der Neutralisation der in flüchtigen Lösungsmitteln gelösten Fette der Fall ist, in geschlossenen Gefäßen arbeiten muß. Einerseits ist der Schaum ein Hindernis für die Zirkulation der Flüssigkeiten, anderseits bedeutet die Notwendigkeit, die entwickelte Kohlensäure aus dem Gefäß heraufzulassen, stets Verluste an den flüchtigen Lösungsmitteln, da diese in erheblichen Mengen von der Kohlensäure mitgerissen werden.But even this measure does not lead to a technically useful one Result. If the neutralizing agents are added in solution, they also form again emulsions, some of which are also used by the ethereal solvents. But the fact continues to show as technically difficult to overcome L assist the formation of a very sewn foam that can hardly be removed. The latter fibelstand is also present when the neutralizing agents, e.g. B. Sodium Carbonate, be applied in dry form. The carbon dioxide escaping during the reaction rises in the liquids to be neutralized and occurs on the surface as thick foam in appearance. The nuisance of foaming is all the more more serious when you look at how to neutralize the in volatile solvents dissolved fats is the case, must work in closed vessels. On the one hand is the foam is an obstacle to the circulation of fluids, on the other hand means the necessity to let the developed carbonic acid out of the vessel always Loss of the volatile solvents, as these are in considerable quantities from the Carbonic acid are carried away.

Will man diese Übelstände vermeiden, so ist man genötigt, diffizile und kostspielige Kondensations- und Dephlegmationsanlagen anzuschließen. Aber selbst, wenn diese Schwierigkeit, die mit dem Entweichen der Kohlensäure verbunden ist, beseitigt wäre, so ist weiter noch sehr hinderlich, daß die Seife in sehr kompakter Form bleibt und von dem Extraktionsmittel für das Neutralfett nur außerordentlich schwer durchdrungen wird.If one wants to avoid these evils, one is forced to make difficult ones and to connect expensive condensation and dephlegmation systems. But even if this difficulty, which is connected with the escape of the carbonic acid, would be eliminated, so is still very cumbersome that the soap is very compact Form remains and of the extractant for the neutral fat only extraordinary difficult to penetrate.

Alle diese ühelstände werden von der Er-,finderin in der einfachsten Weise dadurch; umgangen, daß man mit mindestens der doppelten Menge des theoretisch notwendigen Karbonates arbeitet. Tut man dies, so wird die entwickelte Kohlensäure von dem überschüssigen, unzersetzten Karbonat unter Bildung von Bikarbonat aufgenommen. Es Endet so gut wie gar keine Kohlensäureentwicklung, also auch keine Schaumbildung statt, und das in der Seife verbleibende Bikarbonat spielt die Rolle einer Verteilungssubstanz, so daß eine Seifenmasse feinkörniger Form verbleibt, die von den Extraktionsmitteln für das Neutralfett in allen Teilen gut durchdrungen wird.All of these incapacities are made by the inventor in the simplest way Way by this; circumvented that one with at least twice the amount of the theoretical necessary carbonate works. If you do this, the developed Carbonic acid from the excess, undecomposed carbonate with the formation of bicarbonate recorded. There is almost no carbon dioxide development at all, so none at all Foaming takes place, and the bicarbonate left in the soap plays a role a distribution substance, so that a fine-grained soap mass remains, which are well penetrated in all parts by the extractants for the neutral fat will.
