Aluminophosphate (AlPO) has been synthesized hydrothermally with the variation of moiety of structure directing agent (SDA) as shown in Figure 1. The structure of the obtained AlPO was AlPO-5 (AFI) with the parent SDA, piperidine (PI). Increasing the number of methyl group on PI resulted in the formation of new AlPO structure containing SAS framework when 2,2,6,6,-tetramethylpiperidine (TMPI) was used as SDA. The obtained crystal structure with Rietveld refinement of powder diffraction (Rp=0.078 and Rwp=0.078) was P 4/nnc with a=1.4235 nm and c=1.01008 nm, which was similar to that of STA-6. Thermal decomposition of the obtained AlPO sample induced partial structural change but the sample contained appreciable surface area and pore volume, 140 m2g-1 and 0.073 ccg-1, respectively.
