摘要：
Alkylation of aromatic compounds with ethanol was researched on modified natural zeolites of Kazakhstan deposits. These natural zeolites were identified as Clinoptilolite-Heulandite type. Zeolites were treated by hydrochloric acid, which leads to removal of some of the cations and to dealumination. They were modified by metals of II-III groups and mixed with synthetic zeolites Y and ZSM-5. The catalysts were characterized by elemental analysis, scanning electron microscopy, thermal analysis, BET and temperature-programmed desorption of ammonia. It is shown that natural zeolites, treated by acids and modified by metals, as well as synthetic zeolites can be used as catalysts for process of alkylation of benzene by ethanol. They demonstrate high activity and 71% selectivity in synthesis of ethylbenzene.
