PROCESS FOR REDUCING THE FLUORINE CONTENT OF HYDROFLUOROCARBONS AND HYDROHALOFLUOROCARBONS |
| 摘要 |
The fluorine content of an acyclic saturated compound of the formula CnFaXbHc (wherein each X is independently selected from the group consisting of C1 and Br, and wherein n is 1 to 6, a is 1 to 13, b is 0 to 12, c is 1 to 9, and a + b + c equals 2n + 2) is reduced by reacting the acyclic saturated compound with HC1 in the vapor phase at an elevated temperature in the presence of a catalyst, the mole ratio of HC1 to the acyclic saturated compound being at least about 1:1. |
