FIELD: chemistry. ^ SUBSTANCE: disclosed composition contains the following mixture, wt %: potassium succinate 40-80, potassium formate 10-30, potassium acetate 10-30, of the weight of the mixture with respect to dry substance. The disclosed aqueous composition contains the following mixture, wt %: potassium succinate 60-80, potassium formate 10-20, potassium acetate 10-20, with concentration of the mixture in water of 30-60%. Overall percentage content of potassium acetate and potassium formate in said compositions is essentially the same. Preferably, the mixture is obtained at least partially from a fermentation culture medium containing a carbon source and carboxylic acid-producing microorganisms. ^ EFFECT: composition has effective anti-icing and heat-exchange properties along with resistance to flaking of the concrete of an air-strip and corrosion inhibition. ^ 23 cl, 10 dwg, 3 tbl, 17 ex |
