METHOD FOR PAVEMENT SLIPPERINESS PREVENTION, METHOD FOR DEICING AGENT OBTAINING AND DEICING AGENT TO PREVENT PAVEMENT SLIPPERINESS

FIELD: road usage, particularly methods or arrangements for preventing slipperiness of motor roads, bridges, overpasses, aerodromes, as well as deicing agents. ^ SUBSTANCE: method for pavement slipperiness prevention involves applying deicing agent on pavement. Deicing agent comprises mixture of sodium acetate and magnesium acetate taken in mass ratio of 3:1-1:3 correspondingly. The mixture is obtained by stirring of gaseous chlorine production by-product at 20-80°C temperature. The by-product contains aqueous solution of sodium hydroxide, acetic acid and brucite. Method for deicing reagent production involves mixing aqueous solution of sodium hydroxide, acetic acid and alkaline earth metal compound. The aqueous solution of sodium hydroxide is gaseous chlorine production by-product including aqueous solution of sodium hydroxide. The alkaline earth metal compound is brucite. The mixing operation is carried out at 20-80°C. Deicing agent obtained by above method contains mixture of sodium acetate and magnesium acetate taken in 3:1-1:3 mass ratio correspondingly. The deicing agent may be obtained at first by separately mixing of gaseous chlorine production by-product with acetic acid and then by mixing of obtained sodium acetate and magnesium acetate or gaseous chlorine production by-product is simultaneously mixed with acetic acid and brucite taken in stoichiometric ratio. The deicing composition comprises magnesium acetate as the alkaline earth metal acetate, wherein sodium acetate and magnesium acetate are taken in mass ratio of 3:1-1:3 correspondingly. ^ EFFECT: increased deicing properties, ecological safety and economy. ^ 5 cl, 3 ex, 1 tbl
