Claims
- 1. A liquefied azeotropic composition consisting essentially of hexafluoroethane in combination with an effective amount of hydrogen chloride to form said composition.
- 2. The azeotropic composition of claim 1 consisting essentially of from about 36 to about 40 mole percent hexafluoroethane and about 64 to about 60 mole percent hydrogen chloride, said composition having a boiling point from about −60 degrees C at about 81 psia to about 10 degrees C at about 681 psia.
- 3. An azeotropic composition consisting essentially of hexafluoroethane in combination with an effective amount of hydrogen chloride to form said composition wherein said composition has a boiling point from about −60 degrees C at about 81 psia to about 10 degrees C at about 681 psia.
- 4. The composition of claim 2 or 3 wherein the vapor pressure of the composition is greater than hexafluoroethane and hydrogen chloride.
- 5. A composition consisting essentially of hexafluoroethane and hydrogen chloride wherein said composition has a boiling point from about −60 degrees C at about 81 psia to about 10 degrees C.
- 6. The composition of claim 3 or 5 wherein the amount of hydrogen chloride is from about 60 to about 64 mole percent.
- 7. The composition of claim 5 wherein said composition consists essentially of about 36 to about 40 mole percent hexafluoroethane and about 64 to about 60 mole percent hydrogen chloride.
