Description

Bekanntlich bietet die Schmierung der Zylinder von Benzinmotoren. dadurch gewisse Schwierigkeiten, daß die für Maschinenschmierung gebräuchlichen Schmiermittel, Mineralöle, speziell Zylinderöle, in Benzin löslich sind. Sie werden durch die Benzindämpfe von' den Wandungen der Zylinder abgelöst, und die Zylinder laufen infolgedessen trocken. Man war daher für die Schmierung der Zylinder von Benzinmotoren bisher auf die Verwendung des Rizinusöles angewiesen ; alle anderen fetten öle eignen sich für diesen Zweck nicht, weil sie bekanntlich in Benzin löslich sind.
Es ist nun gelungen, die in Benzin löslichen
As is well known, the lubrication of the cylinders of gasoline engines provides. because of certain difficulties that the lubricants commonly used for machine lubrication, mineral oils, especially cylinder oils, are soluble in gasoline. They are detached from the walls of the cylinders by the gasoline vapors, and the cylinders run dry as a result. One was therefore dependent on the use of castor oil for the lubrication of the cylinders of gasoline engines; all other fatty oils are unsuitable for this purpose because they are known to be soluble in gasoline.
We have now succeeded in solving the gasoline

fetten öle, wie Rüböl, Olivenöl, Sesamöl, Leinöl u. a. m. so umzuwandeln, daß sie ihre Benzinlöslichkeit verlieren und dadurch für den genannten Zweck verwendbar werden.fatty oils, such as rapeseed oil, olive oil, sesame oil, Linseed oil and others m. to convert in such a way that they lose their gasoline solubility and thereby for can be used for the stated purpose.

Das Verfahren besteht darin, daß man die genannten öle zunächst in üblicher Weise durch Behandeln mit Luft in der Wärme in sogenannte geblasene Öle umwandelt und durch die so vorbehandelten Öle einen Wasserdampf strom längere Zeit hindurchgehen läßt. Während die öle nach dem Behandeln mit Luft in Benzin' gut löslich sind, werden sie nach der Behandlung mit Wasserdampf in Benzin schwer löslich bis ganz unlöslich.The process consists in that the oils mentioned are first carried out in the usual way Treating with air converts the heat into so-called blown oils and through the so pretreated oils are allowed to pass through a stream of steam for a long time. While the Oils are readily soluble in gasoline after treatment with air, they become after treatment Slightly soluble to completely insoluble in gasoline with steam.

Beispiel:Example:

.2000 kg Olivenöl werden bei 150 bis 160 ° mit ·. Luft behandelt, bis die Viskosität des Rizinusöles erreicht ist. Alsdann wird jo Stunden lang ein Strom von Wasserdampf durch das Öl hindurchgeleitet. -.2000 kg of olive oil are mixed at 150 to 160 ° ·. Treated air until the viscosity of the castor oil is reached. Then jo hours will be long a stream of water vapor passed through the oil. -

Die Temperaturen, bei denen die öle mit Luft behandelt werden, liegen zwischen 100 ° und der kritischen Temperatur, d. h. derjenigen Temperatur, bei der Selbsterhitzung während des Durchblasens eintritt.The temperatures at which the oils are treated with air are between 100 ° and the critical temperature, d. H. that temperature at which self-heating during blowing through entry.

Von Vorteil ist es, statt gewöhnlichen Wasserdampf überhitzten Dampf anzuwenden und die Behandlung unter einem Drucke von 5 bis 10 Atm. vorzunehmen.It is advantageous to use superheated steam instead of normal steam and the treatment under a pressure of 5 to 10 atm. to undertake.

Die so behandelten öle besitzen neben ihrer BenzinschwerlÖslichkeit eine hohe Viskosität, die sie für Schmierzwecke besonders geeignet macht.The oils treated in this way have in addition to their Gasoline difficult solubility has a high viscosity, which makes it particularly suitable for lubrication purposes power.

Geblasene öle sind bereits in Verbindung mit Mineralölen als Schmiermittel verwendet worden. Die nach vorstehendem Verfahren behandelten öle sollen dagegen nicht mit Mineralöl zusammen, sondern allein zur Anwendung gelangen. Auch steht die Schwerlöslichkeit der so behandelten öle ihrer Mischung mit Mineralöl im Wege. In der Literatur ist erwähnt; daß auch die Mischungen von geblasenen ölen mit Mineralölen die Neigung zeigen, sich zu entmischen, jedoch ist immerhin eine einigermaßen haltbare Mischung möglich, insbesondere bei geringem Ölsäurezusatz. Die nach dem neuen Verfahren behandelten öle lassen sich aber mit Mineralölen in gewissen Verhältnissen. überhaupt nicht mischen, auch nicht auf Zusatz von geringen Mengen ölsäure.Blown oils are already used in conjunction with mineral oils as lubricants been. In contrast, the oils treated according to the above process should not be included Mineral oil together, but only to be used. The poor solubility is also available the oils treated in this way prevent them from being mixed with mineral oil. In the literature is mentioned; that the mixtures of blown oils with mineral oils also have the tendency show to separate, but at least a reasonably stable mixture is possible, especially with a low addition of oleic acid. The oils treated according to the new process but can be used with mineral oils in certain proportions. don't mix at all, too not on the addition of small amounts of oleic acid.
