一般的手順に従って、1,1,1,3,3,3−ヘキサフルオロプロパン、CF3−CH2−CF3(R 236fa)の脱フッ化水素を、0.62gの触媒を使用して行った。異なる温度での触媒上の脱フッ化水素の結果をオンラインGCによって追跡し、1Hおよび19F NMR分光分析法によって確認した。
実施例4:γ−Al2O3担持HS−AlF3前駆体の製造
初めに、γ−Al2O3(10g、ペレット3mm直径)(空気中900℃で12時間カ焼し、それによるα−Al2O3への転化がX線回折分析で全く検出できなかったもの)を、水を含まないイソプロパノール(15mL)中のアルミニウムトリイソプロポキシド(Al(OiPr)3)(1.2g)の撹拌溶液に加えた。撹拌を約0.5時間続行し、次に、水を含まないイソプロパノール(6mL)に溶解させた18ミリモルのフッ化水素を加え、さらに約1.5時間撹拌した。混合物を次に、ロータリーエバポレーターに入れ、減圧下、70℃で溶媒を除去し、約11gのγ−Al2O3担持HS−AlF3前駆体を得た。
実施例4に従って調製した担持前駆体(約2g)を、垂直ステンレススチールチューブ反応器内の銀ウールプラグ上に装填した。CHClF2(4mL/分)とN2(20mL/分)との混合物をこの試料に通し、反応器の温度を250℃までゆっくり上げた。全体で6時間後に反応器を冷却し、Al2O3上の4.9%HS−AlF3装着に相当する、約1.9gの触媒を湿気の排除下で取り出した。
試験反応として、最強の既知ルイス酸(SbF5、ACF、HS−AlF3)によって触媒する必要がある、1,2−ジブロモヘキサフルオロプロパンの2,2−ジブロモヘキサフルオロプロパンへの接触異性化を研究した。約20mgのHS−AlF3/γ−Al2O3を、湿気の排除下で、磁気攪拌バーを備えた小さいガラス容器に入れ、ゴムキャップで密封した。ゴムキャップを通して、約300μLのCBrF2CBrFCF3を注射器で加え、混合物を室温で2時間撹拌した。次に、少量の液体を容器から取り出し、CDCl3と混合し、19F−NMR分析にかけた。分析は、CBrF2CBrFCF3の30%がCF3CBr2CF3に転化されたことを示した。
ステンレススチールまたは溶融シリカチューブ反応器(8mmID、380mm長さ)に、上の実施例2に記載したように調製した、γ−Al2O3によって担持されたHS−AlF3を装填した、触媒床を銀または石英ウールのプラグによって垂直反応器の中央に保持した。脱フッ化水素実験は、それぞれのN2希釈HFCガス(HFC:N2=1:4;全流量2.5mL/分)を指示温度で反応器に通して行い、ガス状流出物をフッ化ナトリウムペレットまたは水酸化カリウム水溶液に通してHFをガス洗浄し、次にGC(Porapak Qキャピラリーカラムを備えた島津GC17A)によってオンライン分析した。別個の実験で、GCによって特定された生成物を、CDCl3中のそれらの溶液の1H−および19F−NMRによって確認した。
一般的手順に従って、1,1,1,2−テトラフルオロエタン、CF3−CFH2(R 134a)の脱フッ化水素を、2gの担持触媒を使用して行った。異なる温度での触媒上の脱フッ化水素の結果をオンラインGCで追跡し、1Hおよび19F NMR分光分析法によって確認した。
一般的手順に従って、1,1,1,2,3,3−ヘキサフルオロプロパン、CF3−CFH−CHF2(R 236ea)の脱フッ化水素を、1.97gの担持触媒を使用して行った。異なる温度での触媒上の脱フッ化水素の結果をオンラインGCで追跡し、1Hおよび19F NMR分光分析法によって確認した。
実施例4で上記の通り調製した触媒を使用した。それは、約3mmの直径のAl2O3ビーズに担持された、15重量%のHS−AlF3を含有した。
13C:CF3 δ=125.1ppm(q);CH2 δ=35.3ppm;CF δ=150.1ppm;CH2=CF δ=35.3ppm
1H:CH 2 δ=3.17ppm(dq);CH(C2原子上のFに対してシス)δ=5.04ppm(dd);CH(C2原子上のFに対してトランス)δ=4.54ppm(dd)
