  Mélanges carburants stables . 



   Cette invention se rapporte à la préparation de mélanges carburants stables ,qui, en plus d'hydrocarbures liquides divers , renferment un ou plusieurs alcools,monovalents.. 



   Il existe de nombreuses formules de tels carburants,dans lesquels en plus des corps alcooliques , entrent de l'essence de pétrole ou du benzol ou ces deux corps à la fois. 



   Ces mélanges carburants exigent des constituants pratiquement anhydres , car en présence de faibles quantités d'eau , ils présentent leplus souvent l'inconvénient de ne pas être   stables,c'est-à-dire   de donner lieu à la température ordinaire à deux couches liquides; ce phénomène peut d'ailleurs se présenter en l'absence d'eau,lorsqu'il se produit unabaissement plus ou moins marqué de température . En pratique ,un mélange carburant destiné auxmoteurs à explosion doit rester parfaitement homogène jusqu'à des températures d'environ -10 . 



   On a déjà proposé pour réaliser cette condition indispensable et pour remédier à l'introduction accidentelle d'eau d'additionner ces carburants complexes de certains corps à fonction hydroxylée ,tels que les phénols, les crésols, le terpinéol ,le cyclohexanol, les alcools isopropyliques , 

 <Desc/Clms Page number 2> 

 butyliques et amyliques. 



   Suivant l'invention il a été trouvé que la stabilité de ces carburants complexes renfermant soit du méthanol industriel, soit de l'éthanol industriel ,tels qu'ils peuvent être obtenus par les procédés de synthèseou autres actuellement connus, soit leur mélange, pouvait être également réalisée dans une large mesure par 1'introduction de produits non encore employés dans ce but jusqu'à présent.

   Ces corps sont soit l'acide oléique ,soit une base ou un mélange de bases pyridiques, la pyridine ,par exemple; ces corps peuvent d'ailleurs être utilisés seuls ou en mélange , dans cedernier c as , 1 es résultats les plus favorables sont obtenus lorsque l'acide oléique et la base pyridique se trouvent en proportions équimoléculaires , réalisant ainsi ce que l'on pourrait appeler ,par exemple dans le cas d'emploi de la pyridine , de   l'oléatc  de pyridine . 



   Ces carburants grâce à la   présence   de ces corps unisseurs nouveaux , montrent une augmentation manifeste de rendement dynamique ,ce qui est probablement dû à une carburation plus homogène . 



   Il est donné ci-dessous un exemple non limitatif de l'influence comme tiers-solvant du mélange équimoléculaire d'acide oléique et de pyridine . 



   Le mélange de 18 volumes de méthanol , de 54 volumes d'essences ordinaires de pétrole et de 18 volumes de benzol donne lieu à une séparation en deux couches si l'on introduit à la   température   ordinaire 0,5 volume d'eau ou si on le refroidit en l'absence   d'eau ,   Ces phénomènes qui présentent de graves inconvénients pratiques et restreignent considérablement les conditions d'emploi de ce mélange carburant ,sont complètement 

 <Desc/Clms Page number 3> 

 annihilés si l'on ajoute à celui-ci 0,9% volume de ce que nous avons appelé l'oléate de pyridine . L'addition supplémentaire de 9 volumes   d'alcool   éthylique augmente encore la stabi.lité  du.   mélange . 



   Les quantités de ces tiers-solvants nouveaux à employer varient évidemment avec les compositions des mélanges carburants et doivent être déterminées dans chaque cas particulier.

  Stable fuel blends.



   This invention relates to the preparation of stable fuel mixtures which, in addition to various liquid hydrocarbons, contain one or more alcohols, monovalent.



   There are many formulas of such fuels, in which in addition to alcoholic substances enter petroleum gasoline or benzol or both substances at the same time.



   These fuel mixtures require practically anhydrous constituents, because in the presence of small amounts of water, they most often have the drawback of not being stable, that is to say of giving rise at ordinary temperature to two liquid layers. ; this phenomenon can moreover occur in the absence of water, when a more or less marked drop in temperature occurs. In practice, a fuel mixture intended for internal combustion engines must remain perfectly homogeneous down to temperatures of around -10.



   To achieve this essential condition and to remedy the accidental introduction of water, it has already been proposed to add these complex fuels of certain bodies with a hydroxyl function, such as phenols, cresols, terpineol, cyclohexanol, isopropyl alcohols. ,

 <Desc / Clms Page number 2>

 butyls and amyls.



   According to the invention it has been found that the stability of these complex fuels containing either industrial methanol or industrial ethanol, such as they can be obtained by the currently known synthetic or other processes, or their mixture, could be also achieved to a large extent by the introduction of products not yet employed for this purpose until now.

   These bodies are either oleic acid or a base or a mixture of pyridic bases, pyridine, for example; these bodies can moreover be used alone or in mixture, in this last case, the most favorable results are obtained when the oleic acid and the pyridic base are in equimolecular proportions, thus achieving what one could call , for example in the case of use of pyridine, pyridine oleate.



   These fuels, thanks to the presence of these new unifying bodies, show a manifest increase in dynamic efficiency, which is probably due to a more homogeneous carburation.



   A non-limiting example of the influence as third-solvent of the equimolecular mixture of oleic acid and pyridine is given below.



   The mixture of 18 volumes of methanol, 54 volumes of ordinary petroleum spirits and 18 volumes of benzol results in a separation into two layers if 0.5 volume of water is introduced at room temperature or if one cools it in the absence of water.These phenomena which present serious practical drawbacks and considerably restrict the conditions of use of this fuel mixture, are completely

 annihilated if we add to this 0.9% volume of what we called pyridine oleate. The additional addition of 9 volumes of ethyl alcohol further increases the stability of the. mixed .



   The amounts of these novel third-solvents to be employed obviously vary with the compositions of the fuel mixtures and must be determined in each particular case.
