Low-temperature anti-icing reagents in aqueous salt systems containing acetates and formiates

Abstract

Ice-melting polytherms in binary and ternary aqueous salt systems containing metal and ammonium acetates and formiates were studied in the temperature range of 0 to −70°C. A number of salt mixtures that form low-temperature eutectics with ice were revealed to be promising as a basis for the development of anti-icing reagents. The properties of these salt mixtures, such as ice-melting ability, the character of their action on cement concrete, and corrosion activity with respect to metals and alloys, were estimated. An efficient corrosion inhibitor was selected.
