Azeotrope-like composition of 2-chloro-3,3,3-trifluoropropene (HCFC-1233xf) and hydrogen fluoride (HF) |
| 摘要 |
Provided are azeotropic and azeotrope-like compositions of 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) and hydrogen fluoride (HF). Such azeotropic and azeotrope-like compositions are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf). |

1. A method of forming an azeotropic or azeotrope-like composition which comprises forming a blend consisting essentially of from about 79.3 mole percent to about 85.3 mole percent hydrogen fluoride and from about 14.7 mole percent to about 20.7 mole percent 2-chloro-3,3,3-trifluoropropene to thereby form an azeotropic or azeotrope-like composition having a boiling point of from about 0° C. to about 61° C. at a pressure of from about 15 psia to about 107 psia. |
