Description

Verfahren zur Zerlegung von Neutralöl und freie Fettsäuren enthaltenden Gemischen. Neutralöle sind auch .in konzentriertem Alkohol praktisch unlöslich. Dagegen werden nicht unerhebliche Mengen Netitralöl gelöst, wenn in dem Gemischgleichzeitig freie Fettsäuren enthalten sind. Dieses ist -ein Nachseil, der sich bei dem Enfisäuren von Fetten mittels Alkohol und ähn,l,icih wirkenden Lösungsmitteln, wie Methylalleohol, Azeton u. dlgl., -bemerkbar macht, @da das Waschmittel nicht nur,dde freien Fettsäuren., sondern auch beträchtliche Anteile des Neutralöls .aufnimmt.Process for the decomposition of neutral oil and containing free fatty acids Mix. Neutral oils are also practically insoluble in concentrated alcohol. On the other hand, not inconsiderable amounts of netitral oil are dissolved when in the mixture at the same time Free fatty acids are included. This is a drag on the defic acids of fats by means of alcohol and similar solvents, such as methyl alcohol, Acetone and the like makes it noticeable, @ because the detergent not only contains the free fatty acids., but also a considerable proportion of the neutral oil.

Diesem Mangel 'kann .man durch Ver--lünnen des Alk ohöls abhelfen, nadhdiem die Entsäu:erung stattgefunden hat. In dem verdünnten Lösungsmittel :ist nämlich, nur noch freie Fettsäure, nicht aber Neutralöl löslich, so daß sich dieses glatt .aibscheidet und .von ,der Übrigen Flüssigkeit getrennt werden kann.This deficiency can be remedied by diluting the alcohol, nadhdiem the deacidification has taken place. In the diluted solvent: is namely, only free fatty acid, but not neutral oil soluble, so that this is smoothly separated and can be separated from the rest of the liquid.

Das Verdünnen der großen Mengen Alkohol o. ,digl."die zum Entsäuern notwendig sind, ist jedoch wenig zweckmäßig, da d-i-es,es die Anwendung einer entsprechenden Wär-emenge erfordert, um das Lösungsmittel zur Befreiung von der freien Fettsäure zu verdampfen und @es dann zur Wiedergewinnung zu konzentrieren.The dilution of large amounts of alcohol or the like for deacidification are necessary, however, is not very practical, since d-i-es, it is the application of a corresponding one Amount of heat required to free the solvent from the free fatty acid to vaporize and then concentrate @es for recovery.

Die Erfindung hat nun ein Verfahren zum Gegenstande, nach, welchem es @gelingt, das Neutralölunter wesentlicher Einschränkung der verdiinnten.Flüssi:gkeit zurückzugewinnen.The invention now has a method for the subject, according to which it succeeds in using the neutral oil with substantial restriction of the diluted liquid to win back.

Zu diesem Zwecke verdampft .man Idas gesamte zur Entsäuerung !benutzte Lösungsmittel, so daß nur das Neutralfett und die freien Fettsäuren zurückbleiben. Diese wäscht man mit Alkohol, von 40 bis 5o Volumpnozent o. dgl. aus. Da zwischen Alkohol dieser Stärke und den N.eutralölen ein wesentlicher Unterschied hinsichtlich der spezifischen Gewidhte besteht, eo trennen sich letztere scharf von der Übrigen Flüssigkeit. Der für ,diese Behandlung erforderkdhe Alkohol beträgt nur ,etwa 1/lo.dies ursprünglich als Waschflüssi.gleeit verwandten.For this purpose, all of Ida's vaporizes were used for deacidification Solvent, so that only the neutral fat and the free fatty acids remain. These are washed out with alcohol, from 40 to 50 percent by volume or the like. Between Alcohol of this strength and the neutral oils make a substantial difference as to the specific devotion exists, eo the latter are sharply separated from the rest Liquid. The alcohol required for this treatment is only about 1/10 of this originally used as a washing liquid.

.Man kann: auch so verfahren, daß man von dem Lösungsmittel nuT den größeren Teil verdampft rund ,den Rückstand auf die gewünschte Stärke .durch Verdünnen mit Wasser einstellt. Zur Vereinfachung des Betr.Iebes wird es sich jedoch im allgemeinen empfehlen, in der zuerst beschriebenen Weise zu arbeiten.One can: also proceed in such a way that one uses the solvent larger part evaporates around, the residue to the desired strength. by diluting adjusts with water. In general, however, it will be used to simplify operation recommend working in the manner described first.
