Description

Verfahren zur Veredelung von Krakdestillatene Es ist bekannt, daß die durch Zersetzungsdestillation von schweren Kohlenwasserstoffen aus Erdöl usw. hergestellten leichten benzinähnlichen Kohlenwasserstoffe einen äußerst unangenehmen Geruch besitzen, der ihrer Verwendung zu manchen technischen Zwecken hinderlich ist, ja sie sogar für manche Zwecke gänzlich unverwendbar machen kann. Es ist auf verschiedenen Wegen versucht worden, diesen Geruch zu beseitigen, beispielsweise durch Anlagerung von Wasserstoff (Hydrierung) oder durch ,Waschen mit starker Schwefelsäure, doch bclieiterte die technische Anwendung der Verfahren teils an den Kosten, teils an den großen dabei entstehenden Verlusten.Process for refining Krakdestillatene It is known that obtained by decomposition distillation of heavy hydrocarbons from petroleum, etc. produced light petrol-like hydrocarbons an extremely unpleasant one Have a smell that hinders their use for some technical purposes is, yes, it can even make it completely unusable for some purposes. It is open Various ways have been attempted to remove this odor, for example by adding hydrogen (hydrogenation) or by washing with strong sulfuric acid, but the technical application of the process was partly due to the cost, partly in the great losses that arise in the process.

Von den Erfindern wurde nun ermittelt. daß die Beseitigung des störenden Geruches, unter gleichzeitiger Entstehung eines wohlriechenden Körpers, ohne erhebliche Kosten und Verluste möglich ist durch einfache Be-. handlung mit einer mäßig starken Schwefelsäure von etwa 1,53 spezifischem Gewicht. bei gewöhnlicher oder etwas erhöhter Temperatur.The inventors have now determined. that the removal of the unpleasant smell, with the simultaneous creation of a fragrant body, is possible without significant costs and losses by simple loading. treatment with a moderately strong sulfuric acid of about 1.53 specific gravity. at normal or slightly elevated temperature.

Die Säure wirkt auf die damit behandelten Produkte der Zersetzungsdestillation derart milde ein, daß nach dem Neutralisieren uni Abdestillieren des behandelten rohen Kohlenwasserstoffes ein wohlriechendes, wasserhelles Erzeugnis erhalten wird, welches bezüglich Farbe, Lichtbeständigkeit, Geruch und Verhalten gegen Schwefelsäure einem guten Handelsbenzin vollständig entspricht, während als Destillationsrückstand eine geringe Menge wieder rückpolymerisierten Öles entsteht, welches, nachdem es einer erneuten Zersetzungsdestillation unterworfen wurde, wiederum in den Verarbeitungsprozeß eingeführt werden kann. Durch Vergleich der Siedepunkte vor und nach der Behandlung wurde festgestellt, daß die Säure fast ausschließlich polymerisierend wirkt in der Art, daß die bei der Zersetzungsdestillation zu weit gespaltenen Kohlenwasserstoffe, soweit sie von etwa 3o bis 7o° C sieden, in solche mit höheren, hauptsächlich zwischen 70 und i5o° liegenden Siedepunkten umgelagert wurden.The acid acts so mildly on the products of the decomposition distillation treated with it that, after neutralization and distilling off the treated crude hydrocarbon, a fragrant, water-white product is obtained, which in terms of color, light resistance, odor and behavior towards sulfuric acid corresponds completely to a good commercial gasoline, while a small amount of re-polymerized oil is produced as the distillation residue, which, after it has been subjected to a renewed decomposition distillation, can be reintroduced into the processing process. By comparing the boiling points before and after the treatment, it was found that the acid has almost exclusively a polymerizing effect in the way that the hydrocarbons which are split too far in the decomposition distillation, as far as they boil from about 30 to 70 ° C., mainly change into those with higher ones boiling points between 70 and 150 ° were rearranged.

F e i s p i e 1 : joo ccm Zersetzungsdestillat aus Erdöl, eine heilbraune übelriechende Flüssigkeit, werden mit io Volumprozent Schwefelsäure von 1,53 spezifischem Gewicht zwei Stunden lang bei gewöhnlicher Temperatur im Rührwerk behandelt und alsdann zwölf Stunden lang stehengelassen: Das Zersetzungsdestillat und die Säure färben sich hierbei tief dunkelbraun, eine Erwärmung tritt nicht ein. Nach dem Abziehen der Säure und nach dein Nachwaschen des Öles wurde das behandelte Öl abdestilliert, ebenso die Waschwässer, und dabei insgesamt erhalten: 440 ccm gereinigtes Destillat von mildem, schwach würzigem Geruch sowie 30 ccm Destillationsrückstand, der zwischen aoo und 36o° siedet und einer erneuten Zersetzungsdestillation unterworfen werden kann. Bei Verwendung dünnerer Schwefelsäure empfiehlt sich Erwärinung auf -.o bis 5o° C zwecks Abkürzung der Rührdauer.Ice pie 1: 100 cc decomposition distillate from petroleum, a medicinal brown, foul-smelling liquid, are treated with 10 percent by volume sulfuric acid of 1.53 specific gravity for two hours at normal temperature in the stirrer and then left to stand for twelve hours: the decomposition distillate and the acid change color deep dark brown, heating does not occur. After removing the acid and washing the oil, the treated oil was distilled off, as was the wash water, and a total of 440 ccm of purified distillate with a mild, slightly spicy odor and 30 ccm of distillation residue boiling between aoo and 36o ° and one can be subjected to renewed decomposition distillation. When using thinner sulfuric acid, we recommend heating to -.o to 5o ° C in order to shorten the stirring time.

Es sei schließlich noch bemerkt, daß es schon ectrgeschlagen_ist, -Krakdestillate mit konzentrierter Schwefelsäure zu reinigen. Hierbei-entstanden aber dadurch große Verluste, daß die konzentrierte Schwefelsäure alle ungesättigten Verbindungen der Krakdestillate zerstörte, wobei unbrauchbare, sogenannte Brandharze entstanden. Demgegenüber sind bei dem Verfahren nach vorliegender Erfindung, das mit verdünnter Schwefelsäure arbeitet, die Verluste nur sehr gering; denn hierbei werden die Krakdestillate nicht verharzt, sondern zii flüssigen, höher molekularen, benzinartigen Kohlemwasserstoffen polvmeris iert.Finally it should be noted that it has already been beaten -Cure distillates with concentrated sulfuric acid. Here-originated but great losses because the concentrated sulfuric acid is all unsaturated Compounds of Krakdestillate destroyed, whereby unusable, so-called fire resins developed. In contrast, in the method according to the present invention, the works with dilute sulfuric acid, the losses are very small; because here the Krak distillates are not resinified, but rather liquid, higher molecular weight, gasoline-like hydrocarbons polymerized.
