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: method for producing a solid deicing material comprises mechanical uniform mixing of a crystalline rock common salt, calcium chloride crystal, crystalline metal corrosion inhibitor elements, crystalline surfactant and crystalline acidity regulator. In the preparation of deicing material each corrosion inhibitor element is saturated with heavier isotopes of carbon ¹³C so that the ratio of carbon isotopes ¹³C to total number of carbon element is size from 0.005 to 0.75. Also, each element of the corrosion inhibitor is saturated with heavy isotopes of nitrogen ¹⁵N so that the ratio of nitrogen isotopes ¹⁵N to the total amount of nitrogen in the element amounts to 0.0001 to 0.1375.

EFFECT: provides increased efficiency of corrosion inhibitor without deteriorating properties of resulting solid deicing material.
