WATER-ACTIVATED, EXOTHERMIC CHEMICAL DEICING FORMULATIONS

摘要

Deicing compositions are provided for removing ice from a surface which include either succinic acid or succinic anhydride, or both, and a neutralizing base such as sodium hydroxide, potassium hydroxide, or ammonium hydroxide wherein the deicing compositions when mixed with water produce succinate salts in a reaction that rapidly releases sufficient heat to melt the ice on the surface and the succinate salts act as a deicer and freezing point depressant. In particular embodiments, the deicing compositions furthe r include a glycol which inhibits reformation of the ice on the deiced surface . The deicing compositions are suitable and effective for airport applications in which corrosion of aircraft alloys and concrete runways are of concern.
