De-icing salts such as sodium chloride or calcium chloride leach into natural waters, strongly affecting their salinity. [1] Ethylene glycol and propylene glycol are known to exert high levels of biochemical oxygen demand (BOD) during degradation in surface waters. This process can adversely affect aquatic life by consuming oxygen needed by ...
In non-aviation contexts, de-icing chemicals typically contain chloride salts, such as calcium chloride (Ca Cl 2). These are prohibited in aircraft deicing fluids due to their corrosive properties. Based on chemical analysis, the U.S. Environmental Protection Agency has identified five main classes of additives widely used among manufacturers:
Verglimit incorporates calcium chloride granules into asphalt pavement. The granules are continually exposed by traffic wear, and release calcium chloride onto the surface. This prevents snow and ice from sticking to the pavement [ 5 ] Cargill SafeLane is a proprietary pavement surface treatment that absorbs anti-icing brines, to be released ...
Calcium chloride, potassium chloride, and magnesium chloride de-icers are less harmful to plants than rock salt when used as directed. Mike Hogan Consider moving plantings away from areas where ...
Calcium chloride was apparently discovered in the 15th century but wasn't studied properly until the 18th century. [11] It was historically called "fixed sal ammoniac" (Latin: sal ammoniacum fixum [12]) because it was synthesized during the distillation of ammonium chloride with lime and was nonvolatile (while the former appeared to sublime); in more modern times (18th-19th cc.) it was called ...
Compass Minerals’ Salt Segment mines, produces, processes and distributes sodium chloride and magnesium chloride in North America and the U.K. The segment’s largest business is highway deicing, which primarily sells bulk rock salt to states, provinces, counties, municipalities and road maintenance contractors for ice control on public roadways.
