Description
等式1: CH3I+XOH→CH3OH+XI、
式中、XIが、ヨウ化カリウム、ヨウ化ナトリウム、又はヨウ化リチウムである。メタノール及びヨウ化アルカリ塩は、塩基性水溶液に容易に可溶性であり、したがってプロセスストリームから容易に除去される。
等式2: CF3I+2XOH→CF2O+XI+XF+H2O
式中、XIが、ヨウ化カリウム、ヨウ化ナトリウム、又はヨウ化リチウムであり、XFが、フッ化カリウム、フッ化ナトリウム、又はフッ化リチウムである。したがって、塩基性水溶液中のアルカリ金属水酸化物の濃度を厳密に制御して、このCF3Iの分解を制限し、精製プロセスにおけるCF3Iの収率を維持する必要がある。
この実施例では、上述の等式1及び2に従った粗CF3Iに対するアルカリ金属水酸化物濃度の影響を実証する。99.88GC面積%のCF3I、0.08GC面積%のCH3I、及び0.04GC面積%の他の有機不純物からなる100gの量の粗出発物質を、室温で6つの150mlシリンダの各々に充填した。6つのシリンダを、粗出発物質で充填する前に排気した。0重量%~20重量%の変動する濃度の水酸化カリウムで、6つの異なる試験溶液を調製した。6つの試験溶液の各々のうちの異なる1つを、50mlの量で6つのシリンダの各々に添加した。試料シリンダの平均圧力は、室温で70psigであった。6つのシリンダを室温で5日間振盪させた。5日間は、典型的なプロセス接触時間よりもはるかに長いが、粗出発物質に対する水酸化カリウムの様々な濃度の相対的な影響の明確な指標を提供するために選択した。
実施例2:粗CF3Iに対するアルカリ金属炭酸塩濃度の影響
実施例3:アルミナを使用した粗CF3Iからの酸不純物及び水の除去
実施例4:粗CF3Iの蒸留
実施例5:粗CF3Iの精製プロセス
