Description
ジクロロトリフルオロエタン(HCFC−123)の製造
連続可動式オートクレーブ中に、ペンタクロロエタン、五フッ化アンチモン及びHFを導入した。HF対SbF5のモル比は約12:1であり、SbF5対出発材料のモル比は5:1であった。その後、オートクレーブを温度100℃及び圧力15バールにした。反応器内容物の一部(触媒約15モル%)を連続的に反応器(オートクレーブ)から取り出し、ストリップ塔に移した。有機成分(殊にHCFC−121、HCFC−122及びHFC−123、並びにペンタクロロエタン)をHF及びHClと一緒に圧力減少下に分離し、オートクレーブ中に返送した。ストリップ塔の残存する部分流を、触媒再生のために、向流で元素状塩素と混合した。
ペルクロロエチレンの完全反応後の塩素化を用いたジクロロトリフルオロエタンの製造
ペルクロロエチレン[0.05モル]を、テフロン内層(Teflon-Inliner)を備えたオートクレーブ中に装入し、ゆっくりと、五フッ化アンチモン[0.1モル]及びフッ化水素[0.88モル]と混合した。オートクレーブを密閉し、撹拌下に1時間、120℃に予熱した油浴中に配置した。この場合、ペルクロロエチレンは完全に変換された。
