実施例1:
CCl3CF2CHFCF3の製造:
Helipackモネル支持材を充填した0.5インチ(12.7mm)×40インチ(101.6cm)の栓流反応器を290℃に加熱した。ヘキサフルオロプロペンとクロロホルムの50/50(モル%)の混合物を、約1.5g/分で反応器中に供給した。反応器の圧力を100psigに維持した。反応器からの流出流を蒸留カラム中に供給し、蒸留によって未反応の薬剤を取り出して、再循環した。生成物:CCl3CF2CHFCF3を次の反応において用いた。
液相フッ素化によるCF3CF2CHFCF3の製造:
SbCl5の存在下においてCCl3CF2CHFCF3の液相フッ素化を行った。約600gのSbCl5を液相反応器に加えた。反応器を80℃〜90℃に加熱し、HFの供給を開始した。約0.1ポンド(4.54kg)のHFが加えられた後、CCl3CF2CHFCF3の供給を開始した。HF及び有機化合物に関する対応する供給は、それぞれ約0.05ポンド/時(2.27kg/時)及び0.04ポンド/時(1.8kg/時)であった。反応中の系に関する平均圧力は約100psig(689.5kPa)であった。
脱ハロゲン化水素化:
ハステロイ−C反応器に50ccのNi−Cu−Cr触媒を充填し、400℃において水素ガスで2時間予備処理した。水素雰囲気を維持しながら、H2と有機化合物のモル比が少なくとも2:1となるように有機化合物:CF3CF2CHFCF3を反応器中に気化させた。有機化合物のブチン生成物への転化を完了させるために、オレフィン生成物をコールドトラップ中に回収し、次に反応器システムを通して再循環した。
シス−1,1,1,4,4,4−ヘキサフルオロ−2−ブテンの選択的製造:
1Lのオートクレーブに、2.0gの触媒(3.5%の鉛で被毒した炭酸カルシウム上の5%パラジウム)及び160mLのエタノールを充填した。次に、オートクレーブ内の内容物を−78℃に冷却した。窒素で60psi(434kPa)に加圧し、次に排気することによって空気を除去した。空気除去連続操作を2回以上繰り返した。次に、ヘキサフルオロ−2−ブチン(32g)を加え、内容物を25℃に加温した。水素を90psig(651kPa)の圧力まで加え、25℃〜28℃の反応温度においてこの圧力に約20時間保持した。オートクレーブの内容物を−78℃の浴を用いて再び冷却し、その後水素ガスを排気した。オートクレーブ内の物質を蒸留して、純度97%のシスヘキサフルオロ−2−ブテン31.6gを得た(収率97.5%)。
