通过对合成全硅方钠石 (Si-SOD)溶胶的液体2 9SiNMR、IR光谱、紫外可见光谱 ,及其晶化产物的13CMASCPNMR和2 9SiNMR的研究表明 ,邻苯二酚在反应混合物中能和硅物种发生反应而生成硅 -邻苯二酚螯合物 .该螯合物在水热条件下是亚稳态的 ,它能缓慢释放出生成分子筛所需要的硅物种 ,使反应体系中的晶核始终处于数量较少状态 ,从而有利于晶体的缓慢长大 Studies on the liquid 29SiNMR, IR and UV-visible spectra and the 13CMASCPNMR and 29SiNMR spectra of the synthesized silica-sodalite (Si-SOD) sol show that the catechol can react with Silicon species react to form a silicon-pyrocatechol chelate that is metastable under hydrothermal conditions, which slowly releases the silicon species needed to form the molecular sieve, allowing the crystals in the reaction system The nucleus is always in a reduced number of states, which is good for the slow growth of crystals
