Description
Verfahren zur Verhinderung der Harzbildung in zur Harzbildung neigenden Spaltbenzinen Die Spaltbenzine, insbesondere die Dampfphasenspaltbenzine, neigen bekanntlich sehr zur Harzbildung. Zur Beseitigung dieses übelstandes hat man bereits vorgeschlagen, solchen Benzinen geringe Mengen gewisser organischer Verbindungen, nämlich Phenole, Kresole, Naphthylamine, Diphenylamine und schließlich auch Aminophenole, zuzusetzen.Process for preventing resin formation in those prone to resin formation Cracked gasoline The cracked gasoline, especially the vapor-phase cracked gasoline, has a tendency known to be very good for resin formation. To remedy this evil one has already suggested adding small amounts of certain organic compounds to such gasoline, namely phenols, cresols, naphthylamines, diphenylamines and finally aminophenols, to add.
Es wurde nun die überraschende Beobachtung gemacht, daß Benzylaminophenol in ungleich höherem Maße die Fähigkeit besitzt, eine solche Harzbildung zu verhindern als die bisher für diesen Zweck vorgeschlagenen Verbindungen und beispielsweise um. mehr als das Achtfache wirksam ist als die nicht substituierten Aminophenole. Die Erfindung kann auch bei solchen stark gekrackten Motorbrennstoffen Anwendung finden, die durch besonders energische bzw. bei hoher Temperatur durchgeführte Krackung oder andere destruktive Destillation bituminöser Stoffe, wie Kohle, Torf, Lignit o. dgl., hergestellt sind.The surprising observation has now been made that benzylaminophenol has the ability to prevent such resin formation to a disproportionately greater extent than the compounds previously proposed for this purpose and for example around. is more than eight times as effective as the unsubstituted aminophenols. The invention has application to such highly cracked motor fuels find, the cracking carried out by particularly vigorous or at high temperature or other destructive distillation of bituminous substances such as coal, peat, lignite o. The like. Are made.
Bei dem neuen Verfahren werden raffinierte Spaltbenzine, die beim Lagern zur Harzbildung oder Verharzung neigen, mit einer kleinen Menge von Benzylaminophenol versetzt. Dieses wird im allgemeinen in Mengen von weniger als o, i %, zweckmäßiger weniger als 0,o50;o, verwendet, und diese Mengen sind praktisch ausreichend, um die Erzeugnisse gegen Harzbildung und Verharzung sowie gegen Verlust der Antiklopfwirkung zu stabilisieren.The new process uses refined mineral spirits that are used in Stores are prone to gumming or gumming with a small amount of benzylaminophenol offset. This is generally more expedient in amounts of less than 0.1% less than 0, o50; o, is used, and these amounts are practically sufficient to the products against resin formation and gumming as well as against loss of the anti-knock effect to stabilize.
Gegebenenfalls kann die Antiklopfwirkung des nach dem neuen Verfahren hergestellten Motorbetriebsstoffes durch Zusatz von geringen Mengen von Bleitetraäthyl oder anderen Antiklopfmitteln noch erhöht werden.If necessary, the anti-knock effect of the according to the new process engine fuel produced by adding small amounts of tetraethyl lead or other anti-knock agents.
