A series of xFe₂(MoO₄)₃/β catalysts with different loading of Fe₂(MoO₄)₃ on the β zeolite were successfully prepared and used as catalysts for the synthesis of 2-ethoxyethyl acetate (EGEA) from ethyl acetate (EA) and 2-ethoxyethanol (EGEE). Fe₂(MoO₄)₃ is successfully loaded on β zeolites according to the results of H₂-TPR, UV–vis spectra, FT-IR spectra and XRD. According to the results of NH₃-TPD and IR spectra of the pyridine adsorbed, the xFe₂(MoO₄)₃/β has high proportion of medium to total acid density and bifunctional acids containing both Brønsted and Lewis acidic sites after the loading of Fe₂(MoO₄)₃. The proportion of medium to total acid density increased from 30.9% to 44.58% with the Fe₂(MoO₄)₃ loading increased from 0 to 13.3 wt%. The conversion of EGEE and selectivity to EGEA over 8.1%Fe₂(MoO₄)₃/β are 74.8% and 100% respectively under the optimal reaction conditions, and the activity of 8.1%Fe₂(MoO₄)₃/β almost maintained unchanged after 4 cycles. The high activity of 8.1%Fe₂(MoO₄)₃/β is attributed to large specific surface area, the high proportion of medium-total acid density (44.58%), high Lewis/Brønsted ratio (3.86) and the synergistic action of the Brønsted and Lewis acidic sites.
