Description
以下の実施例において本明細書に記載した概念をさらに説明するが、これらは、特許請求の範囲に記載した本発明の範囲を限定するものではない。
表面積が約1000m2/gから約1200m2/gの範囲にあるTakeda(商標)活性炭を、1wt%のHNO3水溶液に室温で12時間浸漬させ、その後、脱イオン水で十分に洗浄し、120℃で12時間乾燥させた。次いで、HNO3洗浄済みTakeda(商標)カーボンにKClを付加させ、以下で使用した。
10cc(立方センチメートル)の、25wt%KCl/酸洗浄済みTakeda(商標)カーボンの触媒粒を、0.43インチのI.D.Monel(商標)反応器チューブに装填して、触媒ベッドを形成した。ガス状HCFC−243dbを、4.3ml/分のN2と共に、1.1g/時間の速度で触媒ベッドに通した。反応器チューブからの流出物をGCおよびGC−MSによって分析した。出発材料HCFC−243dbの転換速度、HCFO−1233xfおよびHCFO−1233zdに対する生成物選択性、ならびにHCFO−1233xfに対する脱塩化水素化選択性を以下の表1に列挙した。これは、HCFO−1233xfに対する良好な生成物選択性および良好な脱塩化水素化選択性の両方を示している。
実施例2は、HCFC−243dbの転換速度およびHCFO−1233xfに対する選択性が触媒なしで低かったことを実証する。
