Transformation of 1-Butene over Synthetic Zeolites

Collection of Czechoslovak Chemical Communications, 1992
The behaviour of several zeolites as catalysts for the title reaction has been investigated by means of a continuous flow microreactor. Runs performed at atmospheric pressure indicated that at 423 K the completely protonic forms of the zeolites catalyze just the isomerization reaction.

The influence of iron in synthetic zeolites on the decomposition of perborate

Journal of Chemical Technology and Biotechnology. Chemical Technology, 1984
AbstractCommercial Grace 4A Zeolite exchanged with Fe3+ ions, pumice from different geological flows and their hydrothermally derived zeolites have been characterised as to the distribution and structural configuration of the iron content. Decomposition capacity of perborate (active constituent of detergent formulations) is not only determined by the ...

Isomerisation of 1-methylnaphthalene over synthetic zeolites

Applied Catalysis, 1984
Abstract Activity and durability of variously decationated Ω,X,Y and ZSM5 zeolite catalysts in promoting the title reaction were compared at 210–330°C and in presence of hydrogen. The best results (equilibrium conversion and over 95% selectivity to 2-methyl-naphthalene) were obtained with HNaY, at ca.50% decationation degree.
