Description
Motortreibstoff 1?in großer Nachteil der als Treibstoffe verwendeten Benzin-Alkohol-Gemische, z. B. Benzin-Methanol- oder Benzin-Äthanol-Gemische, liegt darin. <laß sich diese Gemische, insbesondere bei tieferer Temperatur, wie sie z. B. in der kalten Jahreszeit auftritt, und hei erheblichem Alkoholgehalt, leicht entmischen und dadurch zu beträchtlichen Störungen im Motorbetrieb führen.Motor fuel 1? In great disadvantage of that used as fuels Gasoline-alcohol mixtures, e.g. B. gasoline-methanol or gasoline-ethanol mixtures is located in this. <Let these mixtures, especially at lower temperatures, like them z. B. occurs in the cold season, and when there is a considerable alcohol content, easily segregate and thereby lead to considerable malfunctions in engine operation.
I3s wurde gefunden, daß man auch bei tiefen Temperaturen und hei hohem Alkoholgehalt haltbare .'Mischungen von Benzinen und Alkoholen, z. B. Methanol, erhält, wenn inan den Benzin-All<oliol-Geinischen Acetale, d. 1i. Mono- und Dialky lätlier der aliphatischen Aldehydhydrate, insbesondere die niedrig inolekularen, zusetzt. So eignen sich z. B. besonders die Dimethyl- oder Diäthylacetale des Acetaldehyds oder des Formaldehvds.I3s has been found that one can also work at low temperatures and at high temperatures Alcohol content stable. Mixtures of gasoline and alcohol, e.g. B. methanol, received, if in the petrol-alcohol-geinischen acetals, i. 1i. Mono and dialky later of the aliphatic aldehyde hydrates, especially the low molecular weight, clogs. So are z. B. especially the dimethyl or diethyl acetals of acetaldehyde or formaldehyde.
Der Vorteil der Zugabe der Acetale besteht nicht mir darin, daß man aus den sich nicht oder nur unzulänglich ineinander lösenden Mischungsbestandteilen eine selbst bei tiefer Temperatur haltbare Lösung erhält, sondern auch darin, daß die Entmischungstemperatur der Alkohol-Benzin-Lösungen bei Gegenwart geringer Mengen Wasser wesentlich erniedrigt wird, beziehungsweise ein durch geringe Mengen Nasser zur Entmischung gebrachtes Gemisch durch Zugabe der Lösungsvermittler wieder in Lösung gebracht werden kann.The advantage of adding the acetals is not to me that one from the components of the mixture which do not dissolve or only insufficiently dissolve in one another a solution that is stable even at low temperatures, but also in that the demixing temperature of the alcohol-gasoline solutions in the presence of small amounts Water is significantly lowered, or by small amounts of water mixture brought to separation by adding the solubilizer can be brought back into solution.
Man kann 5 bis 50%, insbesondere 1o bis 30%, des Acetals dem Gemisch zusetzen. Im allgemeinen verwendet man eine solche Menge des Acetals, die ausreicht, um aus den Mischungsbestandteilen eine unter den zu verwendenden Bedingungen stets haltbare Lösung herzustellen.You can add 5 to 50%, in particular 10 to 30%, of the acetal to the mixture to add. In general, the amount of acetal used is sufficient to In order to always get one from the mixture components under the conditions to be used to produce a durable solution.
Man kann auf diese Weise beständige Benzin-Alkohol-Gemische herstellen, die io bis 50% und mehr Alkohole enthalten. Beispiel i Ein aus Erdöl durch aromatisierende Druckhydrierung gewonnenes Benzin wird mit 250/0 Methanol versetzt. Bei -f- 1y°' tritt Entmischung ein. Nach Zusatz von 20% Dimeihylacetaldeliydacetal ist das Gemisch bis -3o°'beständig.In this way you can produce stable gasoline-alcohol mixtures, which contain 10 to 50% and more alcohols. Example i A made from petroleum by flavoring Gasoline obtained by pressure hydrogenation is mixed with 250/0 methanol. At -f- 1y ° ' segregation occurs. After adding 20% Dimeihylacetaldeliydacetal the mixture is Resistant to -3o ° '.
Beispiele Ein Erdöldestillatbenzin, das mit Bleitetraäthyl auf Oktanzahl 65 eingestellt ist, wird mit Dimethylacetaldehydacetal oder Diäthylacetaldehydacetal, Methanol und Benzol vermischt, so daB die Mischung enthält: 50% Benzin, 25% Benzol, 20 % Acetal und 5"/o 1lethanol. Das Mischbenzin besitzt die Oktanzahl 74 und ist bis -3o° beständig.Examples A petroleum distillate gasoline, which with lead tetraethyl to octane number 65 is set, dimethylacetaldehyde acetal or diethylacetaldehyde acetal, Methanol and benzene mixed so that the mixture contains: 50% gasoline, 25% benzene, 20% acetal and 5 "/ o 1-ethanol. The mixed gasoline has an octane number of 74 and is Resistant to -3o °.
Beispiel 3 Ein parafhnisches Benzin wird mit Dimethylacetaldehydacetal, Methanol und Äthylalkohol gemischt, so daß die Mischung enthält: 70% Benzin, io% Acetal, io% Methanol und io% Äthanol. Das Gemisch ist bis -30° kältebeständig. An Stelle des genannten Acetals kann nian auch andere Acetale verwenden. Beispiel .I Ein Frackbenzin wird mit Dimethylacetaldehydacetal, Nfethanol und Isobutylalkohol in folgender Weise gemischt: 55°/o Benzin, 25% Acetal, 15 % Methanol und 5% Isoliutylalkohol. Das Gemisch ist bis -30° kältebeständig.Example 3 A parafhnisches gasoline is made with dimethylacetaldehyde acetal, Methanol and ethyl alcohol mixed so that the mixture contains: 70% gasoline, io% Acetal, 10% methanol and 10% ethanol. The mixture is resistant to cold down to -30 °. At Instead of the acetal mentioned, other acetals can also be used. Example .I A fracking gasoline is made with dimethylacetaldehyde acetal, nfethanol and isobutyl alcohol mixed in the following way: 55% gasoline, 25% acetal, 15% methanol and 5% isoliutyl alcohol. The mixture is resistant to cold down to -30 °.
