発明の詳細な記載
本発明の1つの側面は、HFを1つ又はそれを超えるHFC前駆体と反応させて所望のHFCを含む反応生成物流を生じさせる工程を含むHFCの改良された製造方法に関する。図1は、そのような方法を概略ブロック図で表し、ここで、図1中の供給流10により示される1つ又はそれを超えるHFC前駆体は供給流20により示される新たなHFと一緒に反応工程100に導入され、供給流30により示される反応生成物流を生じる。本発明による反応工程の詳細は本明細書の範囲内で大きく変化し得るものであり、よって、現在知られているか又はその後に開発されるであろうすべてのフッ素化工程の詳細は、その反応生成物が未反応HF及び未反応性化合物、特に好ましくはHFとの共沸混合物を形成する未反応性化合物を含む限り、本発明における使用に適合すると考えられる。
