Description

Kraftstoff für Vergasermotore Gegentand der Erfindung sind für Vergasermotore bestimmte Kraftstoffe mit einem Gehalt an Boraminverbindungen der allgemeinen Formel B H3' N R3, in der die drei R gleiche oder verschiedene Kohlenwasserstoffreste sind. Derartige Kraftstoffe zeichnen sich dadurch aus, daß sie Abscheidungen, die bei der Verbrennung der Kraftstoffe im Vergasermotor entstehen können, weitgehend zu verhindern vermögen. Dies gilt besonders dann, wenn die. Kraftstoffe Mittel zur Erhöhung der Klopffestigkeit enthalten, z. B. Bleiverbindungen, wie Tetraäthvlblei, oder aromatische Amine, wie Monomethvlanilin. N-l@lethyl-p-toluidin und Xylidine, bzw. deren Gemische.Fuel for carburetor engines The subject matter of the invention is for carburetor engines certain fuels with a content of boramine compounds of the general formula B H3 'N R3, in which the three Rs are identical or different hydrocarbon radicals. Such fuels are characterized by the fact that they have deposits that occur at the combustion of the fuels in the carburetor engine can largely occur able to prevent. This is especially true when the. Fuels means of Increase in the knock resistance included, z. B. lead compounds, such as tetrahedral lead, or aromatic amines such as monomethvlaniline. N-l @ lethyl-p-toluidine and xylidines, or their mixtures.

Geeignete Boraminverbindungen der angeführten Formel sind z. B. N-Trimethylborazan, N-Triäthylborazan, N-Tripropylborazan und N-Tributylborazan.Suitable boramine compounds of the formula given are, for. B. N-trimethylborazane, N-triethylborazane, N-tripropylborazane and N-tributylborazane.

Der Gehalt an den Boraminv erbindungen in den Kraftstoffen braucht nicht hoch zu sein. Im allgemeinen genügt ein Betrag von 0,01 bis 1%; er richtet sich vor allem nach dem Gehalt der in den Kraftstoffen vorhandenen Mittel zur Erhöhung der Klopffestigkeit. Zweckmäßige Mengenverhältnisse lassen sich von Fall zu Fall leicht durch Vorversuche ermitteln.The content of the boramine compounds in the fuels needs not to be high. In general, an amount of 0.01 to 1% is sufficient; built mainly according to the content of the means for increasing the fuel the knock resistance. Appropriate proportions can be determined on a case-by-case basis easily determined by preliminary tests.

Beispiel Ein Vergasermotor wird mit einem Kraftstoff, der 0.05 Volumprozent Bleitetraäthyl, 2 Volumprozent llonomethylanilin und 0,05 Volumprozent N-Triäthylborazan enthält, 25 Stunden betrieben. Nach dieser Zeit sind lediglich 120/ö der Kolbenmantelflächen mit einer im übrigen nur hauchdünnen Schicht belegt, während die Kolbenmantelflächen eines Motors, der unter vergleichbaren Bedingungen ohne Zusatz des N-Triäthylborazan.s betrieben ist, zu 47n/amiteiner verhältnismäßig dicken harzartigen Schicht überzogen sind.Example A carburetor engine runs on a fuel that is 0.05 percent by volume Tetraethyl lead, 2 percent by volume llonomethylaniline and 0.05 percent by volume N-triethylborazane contains, operated for 25 hours. After this time there are only 120 / ö of the piston surface area covered with an otherwise only wafer-thin layer, while the piston jacket surfaces of an engine, which under comparable conditions without the addition of N-Triäthylborazan.s is operated, coated to 47n / am with a relatively thick resinous layer are.

Borverbindungen sind bereits als Zusätze zu Kraftstoffen bekannt, darunter vor allem Boraminverbindungen, welche Kohlenwasserstoffreste unmittelbar an das Boratom gebunden enthalten. Gegenüber diesen, Boraminverbindungen zeichnen sich die erfindungsgemäß zu verwendenden Boraminverbindungen der allgemeinen Formel B H3 * N R.;, die keine unmittelbar an das Boratom gebundenen Kohlenwasserstoffreste enthalten, dadurch aus, daß sie beim Lagern der Treibstoffe, die mit ihnen versetzt sind und die stets Wasser enthalten, in weitaus geringerem Maße zum Zersetzen neigen.Boron compounds are already known as additives to fuels, including above all boramine compounds, which are hydrocarbon residues directly included bound to the boron atom. Opposite these, draw boramine compounds the boramine compounds of the general formula to be used according to the invention B H3 * N R.; Which have no hydrocarbon radicals directly bound to the boron atom contain, in that they store the fuels that are mixed with them and which always contain water tend to decompose to a much lesser extent.

Dies geht aus Versuchen hervor, bei denen verschiedene Borazane des erfindungsgemäß zu verwendenden Typs B H3 ' N R3 mit B-Triäthylborazan und B-n-Tripropyl-N-triäthylborazan verglichen wurden. Zur Durchführung der Vergleichsversuche wurden jeweils 2.5g Borazan in einer Mischung aus 36 ccm Ligroin und 24 ccm Benzol gelöst; anschließend wurde die Lösung mit 40 ccm Wasser versetzt und geschüttelt. Die verschiedenen Lösungen wurden 70 Stunden auf Raumtemperatur gehalten und dabei wiederholt geschüttelt. Dann wurde das inzwischen gebildete Amin mit Wasserdampf abdestilliert und die Borsäure acidimetrisch in Gegenwart von 'dannit bestimmt. Aus der nachfolgenden Tabelle ist zu ersehen, wieviel Prozent Borazan hierbei jeweils verseift waren. Boraminverbindung hydrolisiert N-Trimethylborazan .............. 0,70/0 N-Triäthylborazan ................ 0.6% N-n-Tripropylborazan ............. 1,0% 1\T-Dimethvlcvclohexvlborazan ..... 1,4% B-Triäthvlborazan ................ 25% B-n-Tripropyl-N-triäthylborazan ... fast 100% This is evident from experiments in which different borazanes of the type B H3 'N R3 to be used according to the invention were compared with B-triethylborazane and Bn-tripropyl-N-triethylborazane. To carry out the comparative experiments, 2.5 g of borazane were dissolved in a mixture of 36 cc of ligroin and 24 cc of benzene; then the solution was mixed with 40 ccm of water and shaken. The various solutions were kept at room temperature for 70 hours and repeatedly shaken. The amine which had formed in the meantime was then distilled off with steam and the boric acid was determined acidimetrically in the presence of 'dannit. The table below shows the percentage of borazane that was saponified in each case. Hydrolyzed boramine compound N-trimethylborazane .............. 0.70 / 0 N-triethylborazane ................ 0.6% Nn-tripropylborazane ............. 1.0% 1 \ T-Dimethvlcvclohexvlborazan ..... 1.4% B-triethvlborazan ................ 25% Bn-tripropyl-N-triethylborazane ... almost 100%
