First claim

Opening claim text (preview).

The invention claimed is: 1. Composition comprising from 60 to 99% by weight of E-1,1,1,4,4,4-hexafluoro-2-butene and from 1 to 40% by weight of at least one chlorotrifluoropropene, wherein the composition is azeotropic or azeotrope-like. 2. Composition comprising from 1 to 30% by weight of E-1,1,1,4,4,4-hexafluoro-2-butene and from 70 to 99% by weight of at least one chlorotrifluoropropene. 3. Composition according to claim 1 characterized in that the chlorotrifluoropropene is 1-chloro-3,3,3-trifluoropropene and 2-chloro-3,3,3-trifluoropropene. 4. Composition according to claim 3 characterized in that the chlorotrifluoropropene is the trans-isomer of 1-chloro-3,3,3-trifluoropropene. 5. A composition comprising from 1 to 25% by weight of E-1,1,1,4,4,4-hexafluoro-2-butene and from 75 to 99% by weight of E-1-chloro-3,3,3-trifluoropropene. 6. Heat transfer composition comprising composition of claim 1 . 7. Blowing agent composition comprising composition of claim 1 . 8. Solvent composition comprising composition of claim 1 . 9. Sprayable composition comprising composition of claim 1 .
