Hydrocracking of Benzene over Various Zeolite Catalysts [PDF]

open access: yes, 1986
ZSM-5, モルデナイトなどの強酸点を有するゼオライト触媒上でベンゼンの水素化分解が進行することを明らかにした。水素化分解活性は用いたゼオライト触媒の種類およびSiO2/Al2O3比に大きく依存し, H-ZSM-5およびH-モルデナイト触媒は高い活性を示したが, H-Y, H-ZSM-34および無定形シリカ•アルミナ触媒は低い活性であった。生成物としては, 分解生成物であるメタン, エタン, プロパン以外にベンゼンのアルキル化されたトルエン, キシレンも比較的高い選択率で得られた。また ...

Hydrocracking of Disilanes

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1957
ジシラン類をアルミナ触媒により水素気流中で分解し,多量のヒドロシランを含むモノシラン類を生成しうることを見出し,メチルクロルシラン製造の残留物油を有用なモノシテン類に変換する方法について研究した。本報では反応条件,ジシランの種類の影響等につき検討した結果,この反応はまずジシランのケイ素-ケイ素結合の切断により起り,生成したシリル基が水素あるいは他の化合物と競争的に反応するものと考えた。
