Process for the preparation of 1,1,1-trifluoro-2,2-dichloroethane |
| 摘要 |
The invention relates to a process for the preparation of 1,1,1-trifluoro-2,2-dichloroethane (F123). This process consists in bringing 1,1,1-trifluoro-2-chloroethane (F133a) into contact with chlorine in the presence of hydrogen fluoride and of a fluorination catalyst. The F133a can be obtained by chlorination of trichloroethylene and the F123 can subsequently be fluorinated to F125.
