ABSTRACT:
Halide brine solutions that contain a dissolved salt of an alkali metal halide or alkali earth metal halide, and an anticorrosion agent comprising an alcohol diglycinate are described. The halide brine solutions may be used to treat transportation surfaces for deicing, anti-freezing, and dust suppression, among other applications. For example, methods of treating a transportation surface with a deicing composition to slow the formation of ice and snow on the surface are described. These methods may include providing the deicing composition that includes an aqueous solution of magnesium chloride, and an ethanoldiglycinate disodium salt. The deicing composition may be sprayed on the transportation surface in an amount effective to slow the formation of ice and snow on the surface.
