Description
Verfahren zur Raffination von Kohlenwasserstoffölen Es ist gelegentlich vorgeschlagen worden, mit stark alkalischer Seifenlösung aus Kohlenwasserstoffölen u. dgl. dunkelgefärbte Ölanteile abzuscheiden, um die Öle dadurch bis zu -einem gewissen Grad zu entharzen und dam.it eine ausreichende Raffination. zu; erzielen. Es hat sichabergezeigt, daß diese Art der Reinigung zu. unscharf ist, weshalb sie für praktische Zwecke nicht in Betracht kommt. Dabei ist eine möglichst weitgehende. Abscheidung der Verunreinigungen von großer Bedeutung.Process for refining hydrocarbon oils It is occasional has been suggested using a strongly alkaline soap solution made from hydrocarbon oils and the like. To separate dark-colored oil components in order to thereby make the oils up to one to de-resinate to a certain extent and thus with sufficient refining. to; achieve. It has been shown, however, that this type of cleaning is too. is out of focus, which is why they is out of the question for practical purposes. This is as far as possible. Separation of the impurities is of great importance.
Als Verbesserung dient das vorliegende Verfahren, welches darin besteht, daß man die Öle durch Kombination von zwei Verfahren behandelt, und zwar i. mit stark alkalischer Seifenlösung (einschließlich der Seifen auscyclischen Fettsäuren), 2. mit einem selektiven Lösungsmittel, z. B. mit Furfurol und eventuell mit einem Zusatz von Hilfslösungsmitteln. Diese Chemikalien können gegebenenf alls getrennt oder auch vorher gemischt dem zu raffinierenden 01 zugegeben werden.The present method, which consists in treating the oils by a combination of two methods, i. with a strongly alkaline soap solution (including soaps made from cyclic fatty acids), 2. with a selective solvent, e.g. B. with furfural and possibly with the addition of auxiliary solvents. These chemicals can be added to the gegebenenf refining alls 01 separately or mixed beforehand.
Die Menge der Chemikalien und das Verhältnis derselben zueinander richtet s,ich nach der Art des zu raffinierenden Öls und nach dem gewünschten Reinheitsgrad.The amount of chemicals and their ratio to each other depends on the type of oil to be refined and the desired degree of purity.
Das Verfahren bietet folgende Vorteile: i. Von einer Waschung der behandelten öle kann man meistens absehen, da die Seife in der Regel ausgefällt wird; 2. die Menge der erforderlichen selektiven Lösungsmiittel ist gering; 3. die ölausbeute ist gut, und zwar besonders auch dann, wenn man die behandelten Öle nachträglich noch mit Schwefelsäure z. B. auf Weißöl#e verarbeitet.The process offers the following advantages: i. You can usually refrain from washing the treated oils, as the soap is usually precipitated; 2. The amount of selective solvents required is small; 3. The oil yield is good, especially when the treated oils are subsequently treated with sulfuric acid, e.g. B. processed on white oil.
Im übrigen bietet auch eine vor dem vorliegenden Verfahren ausgeführte Behandlung der Öle mit Schwefelsäure oft Vorteile, Das Verfahren ist unter anderem auch besonders geeignet für die Behandlung von gebrauchten wäe überhaupt von oxydierten Ölen.Incidentally, there is also one that was carried out before the present proceedings Treatment of oils with sulfuric acid often benefits The procedure is also particularly suitable for the treatment of used wine of oxidized oils in general.
Beispitel i ikg gebrauchtes Transformatorenöl wird bei Zimmerwärme mit iog stark alkalischer chaulmoograsatirein Natron unter intligem Rühren vermischt, worauf man unter weiterem Rühren i5g Furfurol zugibt und so viel 2ogewichtsprozentige Natronlauge hinzufügt, bis sich, die Seifenlauge von dem öl trennt. Der niedergeschlagene Schlamm wird abgetrennt, worauf man das behandelte öl in üblicher Weise bleicht. Beispiel 2 Mineralöldestillat wird in der zu Beispiel i angegebenen Weise behandelt. Nur wird an Stelle der Chaulmoograsäure Rieinusölsäure als Seifengrund-Iage benutzt.Example i ikg used transformer oil is mixed at room warmth with iog strongly alkaline chaulmoograsatirein sodium bicarbonate while stirring carefully, whereupon i5g furfural oil is added with further stirring and enough 2 weight percent sodium hydroxide solution is added until the soapy water separates from the oil. The precipitated sludge is separated off, whereupon the treated oil is bleached in the usual way. Example 2 Mineral oil distillate is treated in the manner indicated for example i. Only rieinusoleic acid is used as a soap base instead of chaulmoogric acid.
