AZEOTROPE-LIKE COMPOSITIONS OF PENTAFLUOROPROPANE AND A PERFLUORINATED FLUOROCARBON HAVING 5 TO 7 CARBON ATOMS OR N-METHYLPERFLUOROMORPHOLINE OR N-ETHYLPERFLUOROMORPHOLINE

摘要

Azeotrope-like compositions comprising pentafluoropropane and a perfluorocarbon having 5 to 7 carbon atoms or N-methylperfluoromorpholine or N-ethylperfluoromorpholine are stable and have utility as refrigerants for heating and cooling, blowing agents, solvents and fire extinguishing agents.
