�ؼ���� ɸ(SAPO-5) �� ϩ 2 6-DIPN

Abstract�� The silicoaluminophosphate molecular sieve(SAPO-5) with relative bigger pore diameter was synthesized hydrothermally and the optimum synthesis condition was determined through experiments.AlOOH was used as the aluminum source,orthophosphoric acid as the phosphor source,tetraethyl orthosilicate as silicon source and triethylamine as the template agent(R),a stainless steel autoclave with Teflon liner as the crystallizing kettle,crystallization temperature was 200 ��,crystallization time was 24 h.The molar ratio of gel composition is SiO_2��Al_2O_3��P_2O_5��R��H_2O=(0.60��2.40)��1.00��1.00��1.00��1.00��40.00.The catalytic activity of SAPO-5 sieve was studied in the alkylation of naphthalene with propylene.The results showed that under certain condition the percent conversion of naphthalene was 97.56%,the yield and selectivity of 2,6-diisopropylnaphthalene(2,6-DIPN) was 40.06% and 41.06% respectively.
