Abstract
The present invention relates to compositions comprising at least one fluoroolefin, HFC-32, and an effective amount of at least one inhibitor. The stabilized compositions may be useful in cooling and heating 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.
Claims26
