METHOD OF SYNTHESIS OF REAGENT BASED ON COMPLEX CALCIUM AND MAGNESIUM COMPOUND OF GENERAL FORMULA (1,0-1,9-Ca(NO3)2Mg(NO3)28CO(NH2)2 AND ANTIGLAZE OF ICE REAGENT |
摘要 |
FIELD: chemical technology of inorganic substances. SUBSTANCE: invention relates to producing antiglaze of ice compositions. Method of synthesis of reagent based on complex calcium and magnesium compounds of the general formula: (1.0-1.9)Ca(NO3)2Mg(NO3)28CO(NH2)2 involves mixing calcium-, magnesium-, nitrate-containing raw with carbamide and surface-active substance and dolomite at ratio CaO/MgO = (1.39-1.9) is used as raw. Dolomite is calcinated, ground and treated with nonconcentrated nitric acid at ratio of solid and liquid phases = 1:(4.2-4.7). Reagent has additionally urotropin as a corrosion inhibitor taken in the amount 0.1-1.01 wt.% or fatty and sulfamic acid salts or tall acid alkyldisubstituted derivatives. Method ensures to use reagent at temperature minus 22 C. EFFECT: decreased cost, enhanced quality of reagent, decreased metal corrosion. 3 cl, 1 tbl, 3 ex |
