다국어 초록 (Multilingual Abstract)

Structure directing agent(SDA) containing piperidine moiety such as piperidine(PI), 2-methylpiperidine(MPI), 2,6-dimethylpiperidine(DMPI) and 2,2,6,6,-tetramethylpiperidine(TMPI), respectively has been utilized to synthesize aluminophosphate zeolite using hydrothermal method. The gel composition was (l.0)Al2O3:(1.0)P2O5:0.76SDA:(45)H2O and the hydrothermal heating was performed in an oven at 443 K and for 7 days at static mode. The obtained zeolitic material contained a lamellar structure when PI was used as the SDA. With a progressive increase of the SDA size, various structures of aluminophosphate including AlPO-5 of AFI structure were obtained. The aluminophosphate of SAS structure was formed when the largest TMPI was utilized as the SDA, which was confirmed by the Rietveld refinement. The result of 27 AI and 31P MAS NMR of the sample suggested that Al and P were incorporated into the framework of the aluminophosphate.
