Abstract

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (“TFMCB”) with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).

Claims (10)

1. An azeotrope or azeotrope-like composition consisting essentially of effective amounts of 1,2,2-trifluoro-1-trifluoromethylcyclobutane and perfluoro(2-methyl-3-pentanone), wherein the azeotrope or azeotrope-like composition has a boiling point of about 48.70° C.±0.01° C. at a pressure of about 14.7 psia±0.2 psia.

2. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists essentially of from about 1 wt. % to about 20 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and from about 80 wt. % to about 99 wt. % perfluoro(2-methyl-3-pentanone).

3. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists essentially of from about 5 wt. % to about 15 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and from about 85 wt. % to about 95 wt. % perfluoro(2-methyl-3-pentanone).

4. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists essentially of from about 8 wt. % to about 12 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and from about 88 wt. % to about 92 wt. % perfluoro(2-methyl-3-pentanone).

5. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists essentially of about 10 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and about 90 wt. % perfluoro(2-methyl-3-pentanone).

6. An azeotrope or azeotrope-like composition consisting of 1,2,2-trifluoro-1-trifluoromethylcyclobutane and perfluoro(2-methyl-3-pentanone), wherein the azeotrope or azeotrope-like composition has a boiling point of about 48.70° C.±0.01° C. at a pressure of about 14.7 psia±0.2 psia.

7. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists of from about 1 wt. % to about 20 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and from about 80 wt. % to about 99 wt. % perfluoro(2-methyl-3-pentanone).

8. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists of from about 5 wt. % to about 15 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and from about 85 wt. % to about 95 wt. % perfluoro(2-methyl-3-pentanone).

9. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists of from about 8 wt. % to about 12 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and from about 88 wt. % to about 92 wt. % perfluoro(2-methyl-3-pentanone).

10. The azeotrope or azeotrope-like composition of claim 1 , wherein the azeotrope or azeotrope-like composition consists of about 10 wt. % 1,2,2-trifluoro-1-trifluoromethylcyclobutane and about 90 wt. % perfluoro(2-methyl-3-pentanone).
