Description

Verfahren zur Vermeidung der Zersetzung eines benzolhaltigen oder aus Benzol bestehenden, Schwefelkohlenstoff enthaltenden, mit Bleitetraäthvl versetzten Kraftstoffes Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von lagerbeständigen, aus Benzol bestehenden oder benzolhaltigen, Schwefelkohlenstoff enthaltenden, mit Bleitetraäthyl versetzten Treibstoffen.Process to avoid the decomposition of a benzene-containing or consisting of benzene, containing carbon disulfide, mixed with lead tetraethylene Fuel The invention relates to a method for the production of storage-stable, consisting of benzene or containing benzene, carbon disulfide containing, with Tetraethyl lead added to fuels.

Wird ein Schwefelkohlenstoff enthaltendes Benzol bzw. Schwefelkohlenstoff enthaltendes Benzol-Benzin-Gemisch zur Erhöhung der Klopffestigkeit mit Bleitetraäthyl versetzt, so führt, wie gefunden wurde, der Schwefelkohlenstoff eine Zersetzung des Bleitetraäthyls herbei. Die durch diese Zersetzung entstehenden Niederschläge von Bleischwefelver-Bindungen, z. B. Bleisulfat, können zu Verstopfungen von Düsen, Verschmutzungen von Filtern usw. führen, und die Zersetzung des Bleitetraäthyls führt zu -einer Verminderung der Klopffestigkeit, so daB solche Mischungen nicht lagerbeständig waren.Becomes a benzene or carbon disulfide containing carbon disulfide containing benzene-gasoline mixture to increase the knock resistance with tetraethyl lead If added, the carbon disulfide has been found to cause decomposition of tetraethyl lead. The precipitates produced by this decomposition of lead sulfur bonds, e.g. B. lead sulfate, can clog nozzles, Soiling of filters, etc. lead, and the decomposition of the lead tetraethyl leads to a reduction in the knock resistance, so that such mixtures do not were storable.

Es wurde nun gefunden, daß die Lagerbeständigkeit herbeigeführt werden kann durch Zusatz von geringen Mengen von in para-Stellung substituierten Phenolen, z. B. p Aminophenol oder p-Dioxybenzol oder deren Subsbitutionsprodukte. Eine Zersetzung des Bleitetraäthyls durch Schwefelkohlenstoff findet dann nicht mehr statt, so daß die Klopffestigkeit erhalten bleibt und Abscheidungen von Bleiverbindungen vermieden werden.It has now been found that shelf life can be brought about can by adding small amounts of phenols substituted in the para position, z. B. p aminophenol or p-dioxybenzene or their substitution products. A decomposition of tetraethyl lead by carbon disulfide then does not find more instead, so that the knock resistance is retained and deposits of lead compounds be avoided.

Es genügt, wenn sehr kleine Mengen solcher Phenole, insbesondere p-Aminophenol, sowie dessen Subst:itutionsprodukte, wie Methyl-p-Aminophenol, Benzyl-p-Aminophenol und ähnliche Stoffe, zugesetzt werden. Auch wenn .diese Stoffe nur in Spuren zugesetzt werden, wird ein beständiger Treibstoff erzielt. Als Zusätze eignen sich auch andere in ,der para-Stellung substituierte Phenole, z. B. Hydrochinon. ' Die im Einzelfalle zu verwendende Menge des Zusatzstoffes kann an Hand einiger einfacher Vorversuche ermittelt werden, :da es nicht erforderlich ist, die Kraftstoffe wochenlang lagern zu lassen, sondern eine Erhitzung des Kraftstoffes in Druckgefäßen auf roo° binnen weniger Stunden Aufschluß über die Lagerbeständigkeit bzw. die Zersetzung des Bleitetraäthyls geben kann. Die Dauer dieser Vorversuche ist je nach dem Gehalt an Schwefelkohlenstoff und Bleitetraäthyl ungefähr 2 bis 4 Stunden. Es kann also ohne Schwierigkeit im Einzelfalle die zuzugebende Minimalmenge ermittelt werden.It is sufficient if very small amounts of such phenols, in particular p-aminophenol, and its substitution products, such as methyl-p-aminophenol, benzyl-p-aminophenol and similar substances. Even if these substances are only added in traces consistent fuel is obtained. Others are also suitable as additives in, the para-position substituted phenols, e.g. B. hydroquinone. 'In the individual case The amount of the additive to be used can be determined on the basis of a few simple preliminary tests can be determined: as it is not necessary to store the fuel for weeks to let, but heating the fuel in pressure vessels to roo ° inside a few hours information about the shelf life or the decomposition of tetraethyl lead can give. The duration of these preliminary tests depends on the carbon disulfide content and tetraethyl lead about 2 to 4 hours. So it can be done without difficulty in the The minimum amount to be added must be determined in individual cases.

Es ist vorgeschlagen worden, zu solchen im wesentlichen ungesättigten Treibstoffen, die im Gasolinbereich sieden und die an sich eine Harzbildung nicht zeigen, dies jedoch dann tun, wenn Bleitetraäthyl zugegeben wird, Aminooxybenzole zuzugeben als Inhibitoren. Bei diesem Vorschlag handelt es sich nicht um eine Verhinderung einer Reaktion des Bleitetraäthyls mit etwaigen Schwefelverbindungen (des Benzins), von denen an der betreffenden Stelle jedoch nicht einmal die Rede ist, sondern um die Tatsache, daß der Autor des Vorschlages der Meinung zuneigt, in dem Äthylfluid enthaltene Stoffe wirkten im Sinne der Harzbildung, so daß der an sich bekannte Zusatz von Inhibitoren ihm selbst bei solchen Benzinen nötig erschien, die an sich, d. h. ohne Zusatz von Bleitetraäthyl, Verharzungserscheinungen nicht zeigen. Die Erfindung hingegen bezieht sich nur auf Benzol bzw. Benzin-Benzol-Mischungen, die schwefelkohlenstoffhaltig sind, da gefunden wurde, daß der Schwefelkohlenstoff zu einer Zersetzung des Bleitetraäthyls führt. Die Entfernung des Schwefelkohlenstoffs aus dem Benzol, in dem sich, je nach dem Schwefelgehalt der verkokten Kohle, wechselnde Mengen befinden, ist nur schwierig möglich, so daß es weit einfacher ist, geringe Mengen .der in para-Stellung substituierten Phenol:e zuzusetzen und dadurch mit Sicherheit eine Zersetzung des Blei'tetraäthyls zu vermeiden.It has been suggested to include those that are essentially unsaturated Fuels that boil in the gasoline range and that do not form resin per se show, but do so when tetraethyl lead is added, aminooxybenzenes to be added as inhibitors. This suggestion is not a prevention a reaction of the tetraethyl lead with any sulfur compounds (of gasoline), which are not even mentioned at the relevant point, but rather around the fact that the author of the proposal is inclined to believe in the ethyl fluid contained substances acted in the sense of resin formation, so that the known per se Addition of inhibitors seemed necessary to him even with such gasoline, which in itself, d. H. without addition of tetraethyl lead, do not show signs of resinification. the In contrast, the invention relates only to benzene or gasoline-benzene mixtures that Containing carbon disulfide, since the carbon disulfide has been found to be too decomposition of the tetraethyl lead. The removal of the carbon disulfide from benzene, in which, depending on the sulfur content of the coked coal, changes It is difficult to find quantities, so it is far easier to find small Amounts of the phenol substituted in the para position: e to be added and thereby with Safety to avoid decomposition of the lead tetraethyl.

Vergleichsversuche r. Ein Reinbenzol (Kahlbaum pro analysi) wurde mit 0.50/0 C S2/1 und o,4 ccm Bleitetraäthyl/1 versetzt. Im Druckgefäß auf zoo° erhitzt, wurde :die beginnende Zersetzung nach 4 Stunden durch Trübung sichtbar. Nach 8 Stunden war der Boden mit einer starken Schicht eines flockigen blei- und schwefelhaltigen Niederschlages bedeckt. Wurde dem gleichen Benzol neben der angegebenen Menge C S2 und Bleitetraäthyl noch o,ooz % Benzylp-Aminophenol zugegeben, blieb :das Benzol unter gleichen Verhältnissen nach 17 Stunden noch völlig blank. Eine Zersetzung des Bleitetraäthyls trat nicht ein.Comparative tests r. A pure benzene (Kahlbaum pro analysi) was made with 0.50 / 0 C S2 / 1 and 0.4 ccm of tetraethyl lead / 1 added. In the pressure vessel to zoo ° heated, became: the incipient decomposition after 4 hours visible through cloudiness. After 8 hours the floor was covered with a thick layer of a flaky lead and sulphurous precipitation covered. Was given the same benzene next to that Amount of C S2 and tetraethyl lead added 0.02% benzylp-aminophenol remained : the benzene is still completely blank after 17 hours under the same conditions. One The tetraethyl lead did not decompose.

2. Ein technisches, Bleitetraäthyl :enthaltendes Benzin-Benzol-Gemisch mit einem Gesamtschwefelgehalt von o,28 % hatte nach 7 Stunden bei r oo° einen starken, flockigen Niederschlag abgesetzt. Ein Zusatz von o,ooo5 % p-Aminophenol verhütete die Ausfällung durch Zersetzung völlig.2. A technical, tetraethyl lead: containing gasoline-benzene mixture with a total sulfur content of 0.28% had a strong, flaky precipitate deposited. An addition of o, ooo5% p-aminophenol prevented the precipitation by decomposition completely.
