Abstract
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 further 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.
