Definitions

• isopropanol and heXylene glycol have been found to be satisfactory anti-icing additives but, unfortunately, for them to be effective, these additives have to be added in amounts that are often uneconomical and, furthermore, since they are Water-soluble, they tend to be removed if the fuel is broughtinto contact with water which is often present in storage tanks or ms.
• a gasoline composition has now been developed in which, to a large extent, the above disadvantages have been overcome.
• a motor gasoline at least 40%, particularly 45%, especially 50%, by volume of which distils over at 100 G, contains a small amount of an additive consisting of a substituted imidazoline having the formula I I (I) 1 ing a hydrocarbon chain having at least carbon atoms,
• X is hydrogen or a low molecular weight hydrocarbon or oxygenated hydrocarbon radical.
• the additives may of course consist of a mixture of molecules of Formula I in which R and X have different values.
• R may be the hydrocarbon residue of a fatty acid RCOOH having 11-25 carbon atoms, most suitably the residue of oleic .acid, stearic acid or coconut fatty acids (the fatty acids obtained from coconut oil).
• X is an oxygenated hydrocarbon radical having not more than five carbon atoms, especially -CH CH OH.
• the gasoline may contain instead of or in addition to a compound of Formula I, a small amount of a monocarboxylic fatty acid salt of such a compound, e.g. an oleic acid, stearic acid or coconut fatty acid salt of such a compound.
• a monocarboxylic fatty acid salt of such a compound e.g. an oleic acid, stearic acid or coconut fatty acid salt of such a compound.
• Compounds of Formula I when combined with fatty acids are effective corrosion inhibitors in fuels.
• the total amount of the additive should, in any case,
• the additives are compatible with other conventional gasoline additives such as anti-knock agents, anti-oxidants, upper cylinder lubricants or ignition control additives.
• the icing time given was, in each case, the mean of three runs.
• a motor gasoline at least 40% by volume of which distills'over at 100 C., containing from 0.00050.05%
• RCOOH having 11-25 carbon atoms and X is a hydroxyl-substituted hydrocarbon radical having 1-5 carbon atoms.
• a motor gasoline at least 40%. byvolume of which distils over at 100 C., containing from 0.00050.05 by volume of an additive consisting of, a' salt of a monocarboxylic fatty :acid' selected'from the group of monocarboxylic :fatty acids consisting of oleic acid, stearic acidand coconut: fatty acids, with a substituted imidazo line having the, formula where R is the hydrocarbon residue of a fatty acid RCOOI-I having,1125 carbon atoms and X is a hydroxylsubstituted hydrocarbon radical having 1-5 carbon atoms.
• a motor gasoline according to claim 9 in which the substituted imidazoline is 1-(2-hydroxyethyl)-2-oleylimidazoline-Z.
