Abstract: Influence of reaction temperature, molar ratio of benzene to 1-alkenes, weight of catalyst and length of hydrocarbon chain of 1-alkenes were tested in alkylation of benzene by 1-alkenes. The liquid-phase alkylation was carried out in autoclave at autogeneous pressure. Synthetic zeolites of Y-type and mordenite in H-forms were tested as solid catalysts. Zeolites were characterized by XRD, N2 adsorption, FTIR with pyridine adsorption and NH3-TPD. The influence of the reaction conditions (temperature, molar ratio benzene to 1-alkenes and weight of catalyst) on the conversion and selectivity to 2-phenyl isomer was studied with different 1-alkenes from C6 to C18. The activity of Y-zeolite was greater then that of mordenite but the selectivity to 2-phenyl isomer was much better in the case of mordenite catalyst.

Keywords: Alkylation, aromatics, 1-alkenes, zeolites
