使用N,N‑二甲基有机模板合成沸石材料
摘要：
本发明提供了制备具有包含YO2和X2O3的结构的沸石材料的方法，其中所述方法包括如下步骤：(1)提供混合物，所述混合物包含一种或多种其铵阳离子具有式(I)[R1R2NR3R4]+(I)的铵化合物，且进一步包含一种或多种YO2料源和一种或多种X2O3料源；(2)使步骤(1)中提供的混合物结晶；其中Y为四价元素且X为三价元素，且其中铵化合物优选为衍化或非衍化N,N‑二甲基吡咯烷化合物、N,N‑二甲基哌啶化合物、N,N‑二甲基六氢氮杂化合物及其混合物，且其中步骤(1)中提供且在步骤(2)中结晶的混合物中具有式(I)的铵阳离子与Y的摩尔比为等于或大于0.25。
摘要（英）：

A process for the preparation of a zeolitic material having a structure comprising YO2 and X2O3 is provided, wherein said process comprises the steps of ( 1 ) providing a mixture comprising one or more ammonium compounds of which the ammonium cation has the formula (I): [R1R2NR3R4+(I) and further comprising one or more sources for Y02 and one or more sources for X2O3; (2) crystallizing the mixture provided in step ( 1 ); wherein Y is a tetravalent element, and X is a trivalent element, and wherein the ammonium compounds are preferably derivatized or underivatized N,N-dimethylpyrrolidinium compounds, Nu,Nu-dimethylpiperidinium compounds, Nu,Nu-dimethylhexahydroazepinium compounds, and mixtures thereof, and wherein the molar ratio of ammonium cation having the formula (I) to Y in the mixture provided in step (1) and crystallized in step (2) is equal to or greater than 0.25.
