Chlorotrifluoroethylene → 5-Chloro-1,2-dimethyl-4,4,5-trifluorocyclohexene

Participants

Reaction Steps

5-chloro-1,2-dimethyl-4,4,5-trifluorocyclohexene was prepared in the same manner as in Comparative Example 4 except that chlorotrifluoroethylene (CTFE), 2,3-dimethyl-1,3-butadiene, and nitrogen gas were continuously injected into the flow reactor at the rates of 33.8 g/hr, 23.8 g/hr and 0.4 mol/hr, respectively. Then, 5.8 g of unreacted chlorotrifluoroethylene (CTFE) was recovered. The resultant was purified by steam distillation, and then the water layer was removed to give 29.8 g of the mixture (GC%=51%).
