- Abstract
Phase equilibria in sections of the phase diagram of the sodium-acetate—sodium-formate-water ternary system with component ratios of NaCH3COO : NaHCOO varying from 3 : 1 to 1 : 3 are studied, and the anti-icing properties of the compositions based on these salts are investigated. Polythermal sections of ice crystallization and the ice-melting ability for each of the prepared compositions are calculated from the experimental data. The formulation with a 1 : 1 ratio of the considered salts has a eutectic temperature of‒22°C, which is 4-6°C lower than the eutectic temperatures of systems based on the individual salts. This formulation displays a high ice-melting ability and can be recommended for use as a de-icer in airports.
