Abstract

The present disclosure relates to compositions comprising at least one fluoroolefin and an effective amount of a stabilizer comprising at least one phosphorus-containing compound selected from the group consisting of thiophosphates, butylated triphenylphosphorothionates, and organophosphates. 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.
