AZEOTROPIC COMPOSITIONS OF 1,1,1,3,3-PENTACHLOROPROPANE AND HYDROGEN FLUORIDE |
| 摘要 |
Provided are methods for forming azeotropic or azeotrope-like mixtures of 1,1,1,3,3-pentachloro-propane (240fa) and hydrogen fluoride. Such compositions are useful as an intermediate in the production of HFC-245fa and HCFO-1233zd. |

1. A method of forming an azeotropic or azeotrope-like composition which consists essentially of blending from about 90 to about 97 weight percent hydrogen fluoride and from about 10 to about 3 weight percent 1,1,1,3,3-pentachloropropane (240fa), which composition has a boiling point of about 24° C. to about 60° C. at pressure of about 17.8 psia to pressure of about 55.4 psia. |
