METHOD FOR PRODUCING ICE-MELTING CHEMICAL Russian patent published in 2015 - IPC C09K3/18 

FIELD: chemistry.

SUBSTANCE: ice-melting chemical is applicable for motorways, bridges, overpasses, take-off runways de-icing. An ice-melting composition is produced by mixing dolomite, hydrochloric and/or acetic acids and water, with a corrosion inhibitor added thereafter. The inhibitor represents a reaction product (RP) 1 mol of fatty amine, 10-30 mol of ethylene oxide and 2 mol of a fluorine compound, or a composition containing, wt %: 5-50 of higher fatty acids, 3-20 of RP or RP mixed with oxyethylated amine (OEA) having a degree of oxyethylation 10-30 and a carbon number C₈-C₂₀, 3-20 of non-ionic surfactant and the rest - an inorganic solvent.

EFFECT: invention provides the ice-melting chemical having a high melting ability, a low corrosion activity and a low freezing temperature.
