Abstract: Magnesium, manganese and zinc incorporated aluminophosphate molecular sieves, MgMnAPO-5 and MnZnAPO-5, have been prepared by hydrothermal methods. The samples have been characterised by the techniques of XRD, FT-IR, 31p and 27Al MAS-NMR spectroscopy, BET-surface area, n-butylamine-TPD and ICP-MS. The catalytic performance of these materials has been examined for ethylation of ethylbenzene with ethanol in the vapour phase. MnZnAPO-5 has been found to be more active than MgMnAPO-5. The products are PDEB (1.4-diethylbenzene), MDEB (1,3-diethylbenzene), ODEB ( 1,2-diethylbenzene), PAB [(1,2,4 and 1,3,5-triethylbenzene) and (1,2.4,5-tetraethylbenzene)]. Maximum conversion (20.1%) has been noted at 350"C over MnZnAPO-5.
