First claim
Opening claim text (preview).
The invention claimed is: 1. An azeotropic or quasi-azeotropic composition consisting essentially of from 75% to 95% by weight of hydrogen fluoride and from 25% to 5% by weight E-1,3,3,3-tetrafluoropropene. 2. The composition as claimed in claim 1 , wherein the composition consists of hydrogen fluoride and E-1,3,3,3-tetrafluoropropene. 3. The composition as claimed in claim 1 , in which the composition consists essentially of from 75% to 85% by weight of hydrogen fluoride and from 25% to 15% by weight of the E-1,3,3,3-tetrafluoropropene. 4. The composition as claimed in claim 1 , in which the composition consists essentially of from 75% to 80% by weight of hydrogen fluoride and from 25% to 20% by weight of the E-1,3,3,3-tetrafluoropropene. 5. The composition as claimed in claim 1 , in which the boiling point of said composition is between −20° C. and 80° C. and at a pressure of between 0.1 and 44 bar absolute. 6. The composition as claimed in claim 1 , in which the boiling point of said composition is between 0° C. and 40° C. and at a pressure of between 0.7 and 18 bar absolute. 7. The composition as claimed in claim 1 , in which the boiling point of said composition is between 0° C. and 40° C. and at a pressure of between 0.9 and 12.5 bar absolute. 8. The composition as claimed in claim 2 , in which the composition consists of from 75% to 85% by weight of hydrogen fluoride and from 25% to 15% by weight of the E-1,3,3,3-tetrafluoropropene. 9. The composition as claimed in claim 2 , in which the composition consists essentially of from 75% to 80% by weight of hydrogen fluoride and from 25% to 20% by weight of the E-1,3,3,3-tetrafluoropropene. 10. The composition as claimed in claim 2 , in which the boiling point of said composition is between −20° C. and 80° C. and at a pressure of between 0.1 and 44 bar absolute. 11. The composition as claimed in claim 2 , in which the boiling point of said composition is between 0° C. and 40° C. and at a pressure of between 0.7 and 18 bar absolute. 12. The composition as claimed in claim 2 , in which the boiling point of said composition is between 0° C. and 40° C. and at a pressure of between 0.9 and 12.5 bar absolute. 13. An azeotropic or quasi-azeotropic composition comprising from 75% to 95% by weight of hydrogen fluoride and from 25% to 5% by weight E-1,3,3,3-tetrafluoropropene, in which the boiling point of said composition is between 0° C. and 40° C. and at a pressure of between 0.7 and 18 bar absolute.
