| Description
| - Acylation of toluene in a liquid phase was investigated on the series of zeolites Y, ZSM-5, mordenite and Beta differing in the structure and geometry of their channel systems and chemical composition. The highest conversion of isobutyryl chloride after 240 min of the reaction was achieved with large pore zeolites Beta and Y having three-dimensional channel system and possessing Si/Al ratio between 15-40. It was observed that the conversion of isobutyryl chloride increases with the increase in the pore size dimensions. Over medium pore zeolite ZSM-5 and large pore one-dimensional mordenite isobutyryl chloride conversions were substantially lower due to the slow desorption and transport of bulky p-isobutyryl toluene, which is strongly held in the channel system of these zeolites. A reaction pathway for acylation reaction was proposed involving the formation of isobutyric anhydride as a reaction intermediate, which is also responsible for acylation of toluene.

- Acylace toluenu byla studována pro různé katalyzátory v kapalné fázi. Vybranými katalyzátory byla řada zeolitů Y, ZSM-5, mordenit a beta, které se liší strukturou a geometrií jejich kanálového systému a chemickým složením. Nejvyšší konverze isobutyryl chloridu bylo dosaženo po 240 min reakce s katalyzátory beta a Y. Zeolity beta a Y mají trojrozměrnou strukturu a jejich poměr Si/Al se pohyboval v rozmezí 20 – 40. Bylo zjištěno, že konverze isobutyryl chloridu roste s rostoucím rozměrem kanálového systému zeolitu. Za použití středněporézního zeolitu ZSM-5 jako katalyzátoru a širokoporézního jednorozměrného mordenitu bylo dosaženo podstatně nižší konverze isobutyryl chloridu. Nižší konverze byla způsobena pomalou desorpcí a pomalejším transportem rozměrného p-isobutyryltoluenu, který byl zadržován kanálovým systémem těchto zeolitů. (cs)
