05-P-15- Synthesis of aluminum phosphite microporous materials N. Li and S. Xiang*

Department of Chemistry, Nankai University, Tianjin 300071, P R. China E-mail." shxiang@public, lpt. tj. cn A series of aluminum phosphite and phosphite-phosphate molecular sieves were synthesized by using P (III) (phosphorous acid) partly or completely replaced P (V) (phosphoric acid) as the source of phosphorus materials. DPA (di-n-propylamine), TEA (triethylamine) and CHA (cyclohexylamine) were used as the template respectively. SEM photographs showed the shapes of these crystalline inorganic solid. It was very interesting that a kind of aluminum phosphite NKX-4 can be synthesized with or without template.

UOP-LLC, 25 East Algonquin Road, Des Plaines, Illinois This paper reports the synthesis and characterization of a new family of indium silicate microporous materials, designated InSi-n. The InSi-n phases have been synthesized with 11 novel framework topologies and contain In/Si ratios of 0.25-1. Most InSi-n phases are stable to calcination to at least 500 ~ and show adsorption behavior that is zeolitic in character. Ion exchange behavior similar to zeolites has also been observed in InSi-n materials. Preliminary structural details include a crystal structure determination of a new topology with 8-ring channels and HREM evidence for large pores in members of the InSi-n family.

05-P-17 - Synthesis and characterization of the silicoaluminophosphate SAPO-47 L. Xu, Z. Liu, P. Tian, Y. Wei, C. Sun and Shinian Li Natural Gas Utilization & Applied Catalysis Laboratory, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, P. O. Box 110, Dalian 116023, [email protected], China Synthesis of a novel small-pore SAPO-47 molecular sieve was described. The effects of the templates and silica concentration in the synthesis gel on the crystallinity and phase purity of SAPO-47 were studied. The results show that pure SAPO-47 could be obtained in a wide range of SIO2/A1203 using sec-butylamine, methylbutylamine or iso-butylamine as templating agent. It is evident that the strength and the amount of the acid sites are related closely to the silicon content and distribution in the framework. SAPO-47 molecular sieve catalyst with expected acidity could be obtained by controlling the SIO2/A1203 in the initial gel.
