Description
Claims (6)
- 5염화 안티몬과 불화수소의 연속류를 반응대에 공급하여 5염화 안티몬을 연속적으로 불소화시켜 불소화 염화안티몬을 생성시키고, 이때 생성된 불소화 염화 안티몬으로부터 부산물인 염화 수소가스는 연속적으로 제거하고 ; 분리된 불소화 염화 안티몬을 다른 반응대에 연속적으로 도입시키며, 이때 여기에 적어도 한개의 불소가 아닌 할로겐원자를 함유하는 할로알칸을 또한 공급하여, 불소화 염화 안티몬과 할로알칸을 반응시킴으로써 할로알칸중의 불소가 아닌 할로겐 부분을 불소화 염화 안티몬의 불소로 치환시키고 생성된 클로로플루오로 알칸 반응생성물을 회수함을 특징으로 하여 할로알칸을 연속적으로 불소화시키는 방법.
- 제1항에 있어서, 할로알칸이 클로로포름인 방법.
- 제1항에 있어서, 할로알칸과의 반응후의 폐 불소화 염화아티몬을 불화수소가 공급되는 반응대에 재순환시키는 방법.
- 제3항에 있어서, 할로알칸이 클로로포름인 방법.
- 제3항에 있어서, 클로로플루오로알칸 반응 생성물을 분별증류법으로 회수하는 방법.
- 제5항에 있어서, 할로알칸이 클로로포름인 방법.
