Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a corrosion inhibiting composition for use in alcohol fuels and normally liquid hydrocarbon fuels containing alcohol. The present invention also relates to alcohol fuels and alcohol-containing normally liquid hydrocarbon fuels that have improved corrosion protection by containing the above-mentioned corrosion-inhibiting compositions.

Alcohol fuels and usually liquid hydrocarbon fuels containing alcohol used in spark ignition and compression ignition internal combustion engines have strong corrosive activity. This strong corrosive activity is generally attributed to the reactivity of the alcohol, and in some cases, for example in the case of ethanol, to the presence of acidic and halogen ion-containing contaminants. That is, alcohol is particularly damaging to non-ferrous metals and metal coatings such as the tin-lead alloy coatings used on the interior surfaces of fuel tanks and the zinc-aluminum alloys used in carburetor construction.

As a result, ninety motor vehicles that use alcohol fuel or normally liquid hydrocarbon fuel containing alcohol have a fuel tank,
There was a strong tendency for corrosion in the fuel line and fuel induction system areas.

The amine salts forming the corrosion inhibitors of this invention can be prepared by simply mixing a phosphoric acid compound and an amine compound at temperatures below about 100°C. Solvents which have proven useful are hydrocarbons or polar salts such as benzene, naphtha, etc. Toluene, xylene, n-hexane, dioxane, chlorobenzene, and kerosene are fuel oils.

Usually, the ratio of both reactants used to prepare the amine salt is 1 equivalent of phosphoric acid compound per equivalent of amine compound so that all free amino groups are converted to the salt. In some cases, only one acidic hydrogen on the monoorganosubstituted phosphoric acid may be used to generate the salt.

That is, the amine salt useful in this invention is produced by reacting an amine compound with 1 to 2 equivalents of a phosphoric acid compound.

The anti-corrosion effect of the above additives was evaluated by the Gracilian Association op Te, Clinical Norms (ABNT).
It was tested according to the method of Test C. In this test, 50 parts of various metal samples (e.g., steel, brass, zinc-aluminum alloy) were immersed in commercially available hydrated ethanol at 3° C. for a continuous 144 hours. At the end of the test, each test was rinsed first with water, then with ketone or other suitable solvent, and then dried. After drying, each sample was weighed and its appearance was visually observed. The weight loss (if any) and appearance of this sample were then compared with a control gasoline consisting of 78-82 volumes of gasoline and 22-18 volumes of absolute ethanol.
It was compared with that of a sample similarly treated with an alcohol blend. In order for a corrosion-inhibiting additive to be effective, a hydration process containing the additive must be used! Both the weight loss and appearance of the samples tested with Nord should be less than 10% of that of the samples treated with the control Ganlin-alcohol blend. The corrosion inhibitors obtained in Examples 2 to 5 were tested according to this method and were found to be effective.1. ,' won. □'1 This invention also provides a fuel composition for use in internal combustion engines, which comprises at least one alcohol (1) having a carbon number of 1 to about 5 and a normally liquid hydrocarbonaceous petroleum fraction 01).
