Preparation method of ITH molecular sieve

The invention discloses a preparation method of an ITH molecular sieve. The method comprises the following steps: mixing a silicon source, a germanium source, a fluorine source, an organic template agent Q, water and an optional heteroatom element X source, and carrying out a crystallization reaction to obtain an ITH molecular sieve; wherein the organic template agent Q is N-ethyl-2-aminomethyl pyrrolidine, and the organic template agent Q is N-ethyl-2-aminomethyl pyrrolidine. According to the method, the low-cost organic template agent is adopted, the Si/Ge molar ratio can be adjusted in a wide area, the synthesis steps are simple, the operability is high, and the synthesis range is wide. 本发明公开了一种ITH分子筛的制备方法。该方法包括：将硅源、锗源、氟源、有机模板剂Q、水和任选的杂原子元素X源混合，进行晶化反应，以获得ITH分子筛的步骤；其中，所述有机模板剂Q为N-乙基-2-氨甲基吡咯烷。该方法采用了一种低成本的有机模板剂，Si/Ge摩尔比可在较宽区域调节，且合成步骤简单、可操作性强、合成范围广。
