Abstract

High-silica-content mordenite with different SiO₂/Al₂O₃ ratios (10.8-32.2) was prepared by the addition of benzene-1,2-diol into the system, 10SiO₂:Al₂O₃:3Na₂O:500H₂O :(0-5.0)C₆H₆O₂ (C₆H₆O₂: benzene-1,2-diol). Experimental results showed that the content of benzene-1,2-diol in the reaction mixture largely influenced the ratios of silicon to aluminium of mordenite crystals and the crystallinity rate. The role of benzene-1,2-diol in the reaction mixture was investigated by ²⁷Al NMR and ²⁹Si NMR, and it was shown that an aluminium-benzene-1,2-diol complex was possibly formed in the reaction system, which may be responsible for the formation of high-silica-content mordenite.
