Description
  • Friedel-Craftsova acylace ferrocenu v kapalné fázi byla katalyzována řadou zeolitů lišících se svou strukturou, velikostí pórů a uspořádáním kanálů. Studován byl vliv struktury zeolitu, dále koncentrace aktivních center na aktivitu a selektivitu dané reakce. Acylačním činidlem pro studovanou reakci byl anhydrit kyseliny octové. Konverze ferrocenu rostla od středně porézních zeolitů k širokoporézním a od jednodimenzionálních k třídimenzionálním zeolitům. Konverze ferrocenu dále rostla s rostoucí koncentrací hliníku v mřížce zeolitu. (cs)
  • The effect of zeolite structure (pore size, channel connectivity) and concentration of active sites on the activity of zeolites in ferrocene acylation with acetic acid derivatives was investigated. The conversion of ferrocene under identical reaction condition increases in the sequence medium-pore zolites < large-pore zeolites and one-dimensional zeolites < three-dimensional zeolites. Ferrocene conversion increases with increasing concentration of aluminium in the framework. Both Broensted and Lewis acid sites contribute to the reaction mainly depending on the acid strength.
