摘要： 通过在两个合成分子筛的体系SiO2-NaOH-EG-R和SiO2-TPABr-NaOH-H2O-R(R:邻苯二酚,EG:乙二醇)中加入邻苯二酚获得了具有较大尺寸和完美形貌的分子筛单晶。29SiNMR,IR和UV-Vis光谱表明,在反应混和物中有硅-邻苯二酚螯合物生成,这种硅的螯合物在形成分子筛大单晶过程中起到了缓释硅源的作用。

Abstract: To obtain large perfect crystals of zeolites, pyrocatechol as an additive was added into the two system: SiO2-NaOH-EG-R and SiO2-TPABr-NaOH-R-H2O (R: pyrocatechol, EG: ethylene glycol). Experimental results showed that the crystals synthesized in the presence of pyrocatechol have much larger size and better morphology than those synthesized in the absence of pyrocatechol. The role of pyrocatechol in the hydrothermal reaction mixture has been characterized by 29SiNMR, IR, and UV-V is spectroscopy, and it was shown that silicon pyrocatechol complex was formed in the reaction system.

Key words: Silica-sodalite, Silicalite-1, Large single crystals, Pyrocatechol, Silicon-pyrocatechol complex
