Abstract

Official abstract text for this publication.

Azeotropic or azeotrope-like compositions are disclosed. The azeotropic or azeotrope-like compositions are mixtures of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene with a second compound selected from the group consisting of methyl formate and HFO-E-1,1,1,4,4,4-hexafluoro-2-butene. Also disclosed are processes of preparing a thermoplastic or thermoset foam by using such azeotropic or azeotrope-like compositions as blowing agents; of producing refrigeration by using such azeotropic or azeotrope-like compositions; of producing cooling; of producing heating; of using such azeotropic or azeotrope-like compositions as solvents; of producing an aerosol product by using such azeotropic or azeotrope-like compositions; of using such azeotropic or azeotrope-like compositions as heat transfer media; of extinguishing or suppressing a fire by using such azeotropic or azeotrope-like compositions; and of using such azeotropic or azeotrope-like compositions as dielectrics.

First claim

Opening claim text (preview).

What is claimed is: 1. A process comprising using an azeotropic or azeotrope-like composition as a power cycle working fluid, wherein said azeotropic or azeotrope-like composition consists essentially of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene and a second compound selected from the group consisting of methyl formate and HFO-E-1,1,1,4,4,4-hexafluoro-2-butene. 2. The process of claim 1 , wherein the second compound is methyl formate. 3. The process of claim 1 , wherein the second compound is HFO-E-1,1,1,4,4,4-hexafluoro-2-butene. 4. The process of claim 1 , wherein the second compound is present in an effective amount to form an azeotropic combination with the HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene. 5. The process of claim 1 , wherein the second compound is present in an effective amount to form an azeotrope-like combination with the HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene. 6. The process of claim 1 , wherein the azeotropic or azeotrope-like composition consists essentially of: (a) from about 11.2 mole percent to about 46.5 mole percent of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and (b) from about 53.5 mole percent to about 88.8 mole percent of methyl formate. 7. The process of claim 1 , wherein the azeotropic or azeotrope-like composition consists essentially of: (a) about 42.1 mole percent of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and (b) about 57.9 mole percent of methyl formate. 8. The process of claim 1 , wherein the azeotropic or azeotrope-like composition consists essentially of: (a) from about 1 to 99 mole percent of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and (b) from about 1 to 99mole percent of methyl formate. 9. The process of claim 1 , wherein the azeotropic or azeotrope-like composition consists essentially of: (a) from about 1 to 9 mole percent of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and (b) from about 91 to 99 mole percent of methyl formate. 10. The process of claim 1 , wherein the azeotropic or azeotrope-like composition consists essentially of: (a) from about 1 to 6 mole percent of HFO-E-1,3,4,4,4-pentafluoro-3-trifluoromethyl-1-butene; and (b) from about 94 to 99 mole percent of methyl formate.
