摘要：

To investigate the role of a complex agent in synthesizing large single crystals of silica-sodalite, pyrocatechol was added as an additive to the system SiO2-NaOH-EG (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 was investigated by Si-29 NMR, IR, and UV-vis spectroscopy, and it was shown that a silicon-pyrocatechol complex was formed in the reaction system.
