METHOD FOR PRODUCING SOLID DEICING MATERIAL BASED ON TABLE SALT AND CALCINED CALCIUM CHLORIDE (VERSIONS) Russian patent published in 2016 - IPC C09K3/18 B01J10/00 C23F11/10 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry, namely to deicing materials with low corrosion activity. Method for producing a solid deicing material comprises a mechanical uniform mixing between a crystal of common salt stone Class I crystalline calcium chloride calcined first technical grade crystalline metal corrosion inhibitor elements, crystalline surfactant crystalline acidity regulator. During production of deicing material each element of corrosion inhibitor is saturated with heavy isotopes of carbon ¹³C such that ratio of carbon isotopes ¹³C to total amount of carbon in element makes from 0.005 to 0.75, and each element of corrosion inhibitor is also saturated with heavy isotopes of nitrogen ¹⁵N so that ratio of nitrogen isotopes ¹⁵N to total amount of nitrogen in element makes from 0.0001 to 0.1375.

EFFECT: higher efficiency of corrosion inhibitor in obtained solid deicing material.
