摘要：

Phase equilibria in sections of the sodium formate-glycerol-water system at temperatures of 0 to -47 degrees C are studied by visual polythermal analysis. The ratio of sodium formate and glycerol in the sections is varied from 3 : 1 to 1 : 3. It is determined that the introduction of glycerol to the sodium formate-water system decreases both the eutectic temperature and the deicing ability of the formate-glycerol mixtures, while the latter remain satisfactory. Identification is made of mixtures that are promising as new deicing agents with good deicing ability and high efficiency at lower temperatures (below -16 degrees C) in comparison with sodium formate.
