The present disclosure relates to compositions comprising at least one fluoroolefin and an effective amount of a stabilizer comprising at least one ascorbic acid, terephthalate, or nitromethane, or mixtures thereof. The stabilized compositions may be useful in cooling apparatus, such as refrigeration, air-conditioning, chillers and heat pumps, as well as in applications as foam blowing agents, solvents, aerosol propellants, fire extinguishants, and sterilants.
A composition comprising:
A method for stabilizing a composition comprising at least one fluoroolefin, said method comprising adding an effective amount of a stabilizer comprising at least one compound selected from the group consisting of terephthalates and nitromethan to the composition comprising at least one fluoroolefin.
A method for reducing degradation of a composition comprising at least one fluoroolefin, wherein said degradation is caused by the presence of inadvertent air in a refrigeration, air-conditioning or heat pump system, said method comprising adding an effective amount of at least one compound selected from the group consisting of terephthalates and nitromethan to the composition comprising at least one fluoroolefin.
