摘　　要：在导向剂存在下,直接由Na_(2)O-SiO_(2)-H_(3)BO_(3)-H_(2)O体系合成B-Si Pentasil型分子筛,找到了合成的最佳条件;建立了反应混合物的三元晶化相区图,考察了分子筛生成的动力学规律及其介稳相的转化;测定了分子筛的吸附和热稳定性。B-Si pentasil type molecular sieve has been synthesized in a Na_(2)O-SiO_(2)-H_(3)BO_(3)-H_(2)O system, by using directing agent. The ternary crystallization area for the molecular sieve was obtained in the reaction mixture. The suitable ranges for the composition of the reaction mixtures have been found. The kinetic process of the crystal growth and transformation of metastable phase were investigated for the molecular sieve.By using high vacuum adsorption methods TG and DTA, the adsorption and the thermal stable properties were determined for this molecular sieve respectively.
