This invention relates to motor-fuels?antler e lates more particularly to the stabilization-of tetraethyl lead in motor fuels.
mide, ethylene dichloride and other substances. in order to, increase the antiknock value of the motor fuel. Most of the gasoline now being sold contains some of this fluid, the amount varying from about 1-3 ccs. per gallon of gasoline. Fuel for special purposes such as aviation gasoline may contain even more. v
It has been found that upon storage, and especially upon exposure to sunlight, the tetraethyl lead tends to deteriorate or decompose with the production'of a haze or cloud formation in the gasoline and with subsequent deposition of a white precipitate. These lead deposits are most noticeable in sight glasses and in the glass bowls of gasoline pumps which become fouled and require frequent cleaning. Loss of the lead compound through precipitation also tends to lower the antiknock value of the motor fuel.
It has now been found that the addition of a' very small amount of the product obtained by the polymerization of alpha-beta unsaturated acid esters will stabilize the lead tetraethyl and retard deposition of deteriorated or partially decomposed tetraethyl lead, and furthermore will prevent the corrosion of metals in contact with wet fuel containing lead tetraethyl.
Polymerized alpha-beta unsaturated esters which may be employed in accordance with our invention to stabilize lead tetraethyl include polymerized esters of acrylic acid, methacrylic acid, fumaric acid, maleic acid, itaconic acid and mesaconic acid and polymerized vinyl esters of fatty acids. These polymers should have a molecular weight of 2,000 to 30,000 or even higher and should be soluble in motor fuel.
The amount of stabilizer used depends on theamount of tetraethyl lead in the gasoline. It has been found that ordinarily 0.1 to 1% by weight of the above stabilizers based on the total weight of gasoline is sufficient for most purposes.
The stabilizers may be added to the gasoline directly or, if necessary, dissolved in a suitable solvent and then added to the gasoline in desired proportions.
The stabilizers may also be added to motor fuel adjuncts such as benzene or alcohol, antioxidants, solvent oils, deactivators etc., or with metal salts of acidic cyanic compounds etc.
These stabilizers may be added directly to the ethyl fluid with additional amounts of solvent, if necessary, and sold and shipped in this form. In this way the addition of tetraethyl lead to gasoline and addition of stabilizer occur simulta.
