PROCESS FOR ISOMERIZING 1,1,2-TRIFLUORO-1,2-DICHLOROETHANE TO 1,1,1-TRIFLUORO-2,2-DICHLOROETHANE |
| 摘要 |
1,1,2-trifluoro-1,2-dichloroethane (A123a) is isomerized to 1,1,1trifluoro-2,2-dichloroethane (A123) by contacting it with AlF3 at temperatures ranging frorn 180.degree. to 400.degree.C. Advantageously, it is operated with mixtures of A123a and/or other chlorofluorocarbons coming from the preparation of A123 by hydrofluorination of perchloroethylene.
