First claim
Opening claim text (preview).
1 - 14 . (canceled) 15 . An azeotropic or quasi-azeotropic composition consisting essentially of hydrogen fluoride and E-3,3,3-trifluoro-1-chloropropene. 16 . The composition as claimed in claim 15 , wherein the composition is azeotropic. 17 . The composition as claimed in claim 15 , wherein the composition is quasi-azeotropic, wherein the pressure difference between the pressure at the dew point and the pressure at the bubble formation point is less than or equal to 5%, on the basis of the pressure at the bubble formation point. 18 . The composition as claimed in claim 15 , wherein the composition has from 5% to 70% by weight of hydrogen fluoride and from 95% to 30% by weight of E-3,3,3-trifluoro-1-chloropropene, the boiling point of this composition is between 0 and 40° C. at a pressure of between 0.9 and 4 bar absolute. 19 . The composition as claimed in claim 15 , wherein the composition has from 10% to 65% by weight of hydrogen fluoride and from 90% to 35% by weight of E-3,3,3-trifluoro-1-chloropropene, the boiling point of this composition is between 0 and 40° C. at a pressure of between 0.9 and 4 bar absolute. 20 . The composition as claimed in claim 15 , wherein the composition consists of hydrogen fluoride and E-3,3,3-trifluoro-1-chloropropene. 21 . The composition as claimed in claim 20 , wherein the composition is azeotropic. 22 . The composition as claimed in claim 20 , wherein the composition is quasi-azeotropic, wherein the pressure difference between the pressure at the dew point and the pressure at the bubble formation point is less than or equal to 5%, on the basis of the pressure at the bubble formation point. 23 . The composition as claimed in claim 20 , wherein the composition has from 5% to 70% by weight of hydrogen fluoride and from 95% to 30% by weight of E-3,3,3-trifluoro-1-chloropropene, the boiling point of this composition is between 0 and 40° C. at a pressure of between 0.9 and 4 bar absolute. 24 . The composition as claimed in claim 20 , wherein the composition has from 10% to 65% by weight of hydrogen fluoride and from 90% to 35% by weight of E-3,3,3-trifluoro-1-chloropropene, the boiling point of this composition is between 0 and 40° C. at a pressure of between 0.9 and 4 bar absolute.
