Abstract

The present invention relates to compositions comprising at least one fluoroolefin and an effective amount of stabilizer that may be an epoxide, fluorinated epoxide or oxetane, or a mixture thereof with other stabilizers. 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.
