- 퍼플르오로에탄의 제조방법에 있어서, 반응기 내에서 이불화 코발트(CoF2)를 불소가스와 접촉반응시켜 삼불화 코발트(CoF3)로 활성화시킨 후, 반응기내에 잔존하는 미반응 불소가스를 황(S)과 접촉 반응시켜 육불화 황(SF6)로 전환시키고 이 육불화 황을 제거하여 미반응 불소가스가 제거된 상기 반응내에서 불화에탄(C2FxHy여기에서 x1, y5, x+y=6이다)을 삼불화 코발트와 300~350℃에서 접촉반응시켜 퍼플르오로에탄을 제조하는 방법.
- 제1항에 있어서, 불화에탄이 1,1,1-트리플루오로, 2,2-디플루오로에탄, 1,1,1-트리플르오로 2-플루오로에탄, 또는 1,1,1-트리플루오로에탄 중에서 선택된 퍼플루오로 에탄을 제조하는 방법.
