Boro-silico-zirconio-aluminophosphate molecular sieves (BSiZrAPO-5) with the structure similar to AlPO 4 -5 were synthesized using the hydrothermal synthesis method. Substitutions of Al and P atoms in the AlPO 4 -5 framework with Si, B and Zr atoms were demonstrated by the variation in unit cell volume, chemical analysis, IR spectrum and 2 7 Al, 3 1 P MAS NMR data. The IR spectrum of adsorption of pyridine and temperature programmed desorption of NH 3 indicate that BSiZrAPO-5 contains more Bronsted and Lewis acid sites than AlPO 4 -5. BSiZrAPO-5 possesses a significant catalytic activity, a high selectivity of 2-phenylalkane (2-LAB) and 3-phenylalkane (3-LAB) and a long life period in the alkylation of benzene with linear olefins. BSiZrAPO-5 may replace HF as an environmentally benign catalyst in linear alkylbenzene production.
