Abstract

The present invention relates to compositions comprising iodotrifluoromethane and an effective amount of at least one stabilizer selected from the group consisting of hindered phenols, thiophosphates, butylated triphenylphosphorothionates, organo phosphates, phosphites, aryl alkyl ethers, terpenes, terpenoids, epoxides, fluorinated epoxides, oxetanes, ascorbic acid, thiols, lactones, thioethers, amines, nitromethane, alkylsilanes, benzophenone derivatives, aryl sulfides, divinyl terephalic acid, diphenyl terephalic acid, ionic liquids, and mixtures thereof. These stabilized iodotrifluoromethane compositions may be useful as working fluids in multiple applications including cooling apparatus, such as refrigeration, air-conditioning, chillers, and heat pumps.
