MULTIFUNCTIONAL ADDITION AGENT FOR AUTOMOBILE GASOLINE

FIELD: petroleum processing, petroleum chemistry, automobile manufacture. ^ SUBSTANCE: invention relates to a multifunctional addition agent designated for using as a component of automobile gasoline. Multifunctional addition agent for automobile gasoline is based on products of interaction of technical alkylsalicylic acids and polyethylenepolyamines of the formula: NH2-(CH2CH2NH)nH wherein n = 1-7 taken in the mole ratio polyethylenepolyamine : technical alkylsalicylic acids = from 1:1 to 1:2 as measured for alkylsalicylic acids and an organic solvent. As an organic solvent the addition agent comprises petroleum oils or their mixtures with the kinematic viscosity value 25 mm2/c, not above, at temperature 100°C and the solidification point -15°C, not above. The addition agent improves washing, anti-oxidative, anti-corrosion and other properties of automobile gasoline and reduces the content of toxic substances in exhausted gases of cars. Using the proposed invention provides increasing production of high-quality non-ethylated gasoline. ^ EFFECT: improved and valuable properties of addition agent. ^ 5 tbl
