Fazoobrazovaniye in system calcium nitrate – water – alcohol at negative temperatures

A study of the solubility in the ternary systems Ca(NO 3) 2 – H 2O – i-C 3H 7OH is of special fundamental and practical interest. This systems are used as low – temperature liquids for industrial refrigerating plants. In the real work as a method of sections at-5 and – 10°С solubility in three-componental systems salt – water – alcohol is investigated. Compositions of balanced liquid and solid phase have been defined, phase diagrams of solubility and positions of homogeneous solutions have been upraised.
