The effects of oxygenated additives (monohydric alcohols and ethers) on the operating conditions (the temperature of turbidity and octane numbers) of automobile gasoline’s have been studied. The syntheses of gasoline-alcohol compositions based on straight-run  gasoline’s, reforming gasolines and low-molecular weight alcohols and ethers have been studied through their phase of stability. It is found that the stability of gasoline-alcohol mixtures depends on the chemical composition of gasoline’s. In addition, the best solubility has been observed with ethanol because it gives more polarity with the aromatic hydrocarbons which are the basic part of reforming gasolines. To obtain the stable gasoline-alcohol mixtures, the qualities of mixtures have been studied with the surfactant nonoil additive AF-9-6, in dosages of 1–3.5%, and its effect on the temperature of turbidity of the gasoline containing no more than 10% ethanol has been studied. The results have shown a reduction up to –320C. The effect of ethers, obtained on the basis of isopropanol and butane- butylenes faction, on the octane characteristic of commercial gasoline has been studied. It is found that when adding 10% ether-additives to straight-run gasoline, the octane number has increased by 10–15 times. It is found that the uses of these oxygenated additives (alcohols and ethers) improve the octane number of gasoline and improve the environmental properties of gasoline as by reducing the benzene content, as well as by reducing exhaust emissions
