    • 본 발명은 고순도 헥사플루오르프로필렌 정제방법에 관한 것으로서, 보다 상세하게는 HFP 내의 불순물을 제거하여 고순도의 HFP를 얻을 수 있도록 한 정제방법이며, 이를 위해, 원료대상이 되는 HFP 내 잔여수분을 제거하고, 잔여수분이 제거된 HFP를 HFP의 비점보다 낮되 HFP에 함유된 저비점 불순물의 비점보다는 높은 온도로 설정하여, HFP는 액체상태를 유지하되 기체상태가 된 저비점 불순물은 외부로 배기시키며, 이어, 액상의 HFP를 HFP의 비점보다 높되, HFP에 함유된 고비점 불순물의 비점보다는 낮게 설정된 온도로 설정하여, 액체상태가 되는 HFP 내 고비점 불순물과는 달리 기체상태가 되는 HFP를 별도의 저장수단에 저장시킨 후, 남아있는 고비점 불순물의 제거를 위해, 남아있는 고비점 불순물을 고비점 불순물의 비점보다 높은 온도로 저장수단 내 온도를 설정하여, 고비점 불순물을 기화시켜 외부로 진공배기시킴으로써, HFP 내 불순물을 비점차이를 이용해 분리하여 고순도의 HFP 획득이 가능토록 한 고순도 헥사플루오르프로필렌 정제방법에 관한 것이다.
