Description
. Verfahren zur Erhöhung der Kompressionsfestigkeit von Motortreibmitteln Es ist bekannt, daß durch Zusatz von Anilin die Klopffestigkeit von Benzinen gesteigert werden kann, so daß sie bei Verdichtungsgraden, bei denen das unvermischte Benzin bereits Klopferscheinungen zeigt, nach Anilinzusatz ohne Anstände wirtschaftlich gefahren werden können. Das Verfahren, durch Anilinzusatz klopffestere Benzine zu erzeugen, hat noch keinen Eingang in die Technik finden können, denn Anilin ist in Benzin nur zu einem geringen Prozentsatz löslich. Die Sättigungsgrenze liegt etwa bei 3 %, und über diese Grenze hinaus besteht keine Möglichkeit, die Antiklopfwirkung des Anilins auszunutzen. Auch die Verwendung geringerer Anilinmengen stößt auf Schwierigkeiten, da infolge der mangelhaften Löslichkeit auch die Auflösung geringerer Anilinmengen mit erheblichem Aufwand verbunden ist.. Process for increasing the compressive strength of engine propellants It is known that the addition of aniline increases the anti-knock properties of gasoline can be so that they at degrees of compression in which the unmixed gasoline already shows knocking, economically without hesitation after aniline addition can be driven. The process of making petrol more knock-proof by adding aniline has not yet found its way into technology, because aniline is only a small percentage soluble in gasoline. The saturation limit lies around 3%, and beyond this limit there is no possibility of the anti-knock effect of aniline. The use of smaller amounts of aniline also encounters difficulties because of the poor solubility also the dissolution of smaller amounts of aniline is associated with considerable effort.
Es sind auch Homologe des Anilins schon Treibstoffen zugesetzt worden, und ebenso ist angegeben worden, daß o-Toluidin im Gemisch mit Anilin die Kompressionsfestigkeit eines Kraftstoffes heraufsetzen kann. Es war jedoch nicht bekannt, daß andere Stoffe als o-Toluidin im Gemisch mit Anilin und anderen Aminen in der Weise günstig wirken würden, wie es nach dem Verfahren der Erfindung der Fall ist.Aniline homologues have also been added to fuels, and it has also been stated that o-toluidine mixed with aniline has the compressive strength of a fuel can increase. However, it was not known to have any other substances act as o-toluidine in a mixture with aniline and other amines in this way favorably would, as is the case with the method of the invention.
Es wird durch das Verfahren der Erfindung auf außerordentlichem und bisher unerreichtem wirtschaftlichem Wege möglich, einen allen Anforderungen genügenden Zusatzstoff zur Erzielung besserer Klopffestigkeit zu schaffen.It is made extraordinary and by the method of the invention A previously unattainable economic path is possible, one that meets all requirements To create additive to achieve better anti-knock properties.
Es wurde gefunden, daß, die Verwendung reinen Anilins untunlich ist; denn wenn man bei der Herstellung des als Antiklopfmittel Verwendung findenden Anilins nicht erst auf Reinbenzol hinarbeitet und dieses nitriert und reduziert, sondern vielmehr die Benzole, wie sie auf den Kokereien anfallen, im Originalzustand verarbeitet, erhält man ein Gemisch der verschiedensten aromatischen Amine, die in ihren Antiklopfeigenschaften dem Anilin völlig gleich sind, sich jedoch dadurch auszeichnen, daß sie im Gegensatz zu Anilin in Benzin in jedem Verhältnis löslich sind. Die Anilinhomologen, die als solche benzinlöslich sind, fallen im Verhältnis zu Anilin bei diesem Arbeitsprozeß in genügenden Mengen an, um als Lösungsvermittler zwischen Benzin und Anilin wirken zu können. Bei Durchführung dieser Arbeitsweise erspart man daher i. die Umarbeitung der anfallenden Benzole auf Reinbenzol und z. fallen die obenerwähnten Mischschwierigkeiten fort, so daß man jeden für erforderlich erachteten Anilinzusatz anwenden kann, ohne sich anderer Kohlenwasserstoffe als Lösungsvermittler bedienen zu müssen.It has been found that the use of pure aniline is impractical; because if you find aniline in the production of an anti-knock agent not first working towards pure benzene and nitrating and reducing it, but rather, the benzenes, as they occur in the coking plants, are processed in their original state, a mixture of the most varied aromatic amines is obtained, which in their anti-knock properties are exactly the same as aniline, but are distinguished by the fact that they are in contrast to aniline are soluble in gasoline in any proportion. The aniline homologues known as those that are soluble in petrol fall in relation to aniline in this work process in sufficient quantities to act as a solubilizer between gasoline and aniline to be able to. When carrying out this procedure one therefore saves i. the makeover the resulting benzenes on pure benzene and z. the above-mentioned mixing difficulties fall away, so that any aniline additive that is deemed necessary can be used without having to use other hydrocarbons as solubilizers.
