Abstract: Large pore aluminophosphate-based molecular sieves, MgMnAPO-5 and MnZnAPO-5, were synthesized by hydrothermal methods. The samples were characterised by the techniques of XRD, FT-IR, <sup>31</sup>P and <sup>27</sup>Al MAS-NMR spectra, BET-surface area, <i style="">n</i>-butylamine-TPD and ICP-MS chemical analysis. The catalytic performance of these materials has been examined for ethylation of benzene with ethanol in the vapour phase. The products were ethylbenzene, <i style="">p</i>-diethylbenzene, <i style="">m</i>-diethylbenzene, <i style="">o</i>-diethylbenzene and PAB[(1,2,4 and 1,3,5-triethylbenzene) and (1,2,4,5-tetraethylbenzene)]. Maximum conversion (20.6%) was observed at 400<sup>o</sup>C over MnZnAPO-5.
