Plausibility of potassium ion-exchanged ZSM-5 as soot combustion catalysts
Scientific Reports, 2017 Potassium (K) ion-exchanged ZSM-5 zeolites were investigated for catalytic soot combustion. X-ray absorption fine-structure (XAFS), Raman, in situ IR and NH3-temperature programmed desorption (NH3-TPD) confirmed the location of K+ at the ion-exchanged ...

Fluorination with Complex Fluorine Compounds
The Journal of the Society of Chemical Industry, Japan, 1969 鉄,アルミニウム,アンチモン,ケイ素,チタンなどの6配位錯フッ化物によるハロゲン交換フッ素化反応について研究した。フッ素化の対象としては,四塩化炭素,クロロホルム,ヘキサクロルエタンなどの有機塩素化合物をえらび,オートクレープ中で250ないし350℃で2時間ないし4時間反応させた。この結果,鉄,アンチモン,アルミニウムなどの錯フッ化勃の活性が大きく,ケイ素の錯フッ化物の活性はこれらについだ。これに対し,チタソの錯フッ化物は不活性であることがわかった。鉄,アンチモン,アルミニウムの錯フッ化物の活性が大きいことは,これら錯フッ化物がリガンド交換活性な外軌道または高スピン錯塩であることによるものと考えられる。実際に,反応後の固体をX線回折分析により調べたところ,低配位錯塩NaAIF4 ...

Introduction of Fluorine and Fluorine‐Containing Functional Groups [PDF]
Angewandte Chemie International Edition, 2013 AbstractOver the past decade, the most significant, conceptual advances in the field of fluorination were enabled most prominently by organo‐ and transition‐metal catalysis. The most challenging transformation remains the formation of the parent CF bond, primarily as a consequence of the high hydration energy of fluoride, strong metal—fluorine bonds ...
