摘要： As synthesized by previous methods, ZSM-4 zeolites are crystallized in the presence of substantial amounts of a tetramethylammonium hydroxide or halide. When synthesized in this way, they contain the tetramethylammonium cation as well as a metal cation such as sodium. To obtain a more catalytically active form, the sodium ion must be exchanged to very low levels. Catalysts prepared in this manner have been found to be quite low in stability. By synthesizing these zeolites in the presence of pyrrolidine or choline salts, ZSM-4 having a different organic nitrogen containing cation but the same crystal structure as previously prepared ZSM-4 is obtained. Catalysts made therefrom are, surprisingly, much more stable than those prepared from ZSM-4 made by previous methods.
摘要翻译：通过以前的方法合成，ZSM-4沸石在大量的四甲基氢氧化铵或卤化物存在下结晶。当以这种方式合成时，它们含有四甲基铵阳离子以及诸如钠的金属阳离子。为了获得更具催化活性的形式，钠离子必须交换到非常低的水平。发现以这种方式制备的催化剂的稳定性相当低。通过在吡咯烷或胆碱盐的存在下合成这些沸石，得到具有不同有机含氮阳离子但具有与先前制备的ZSM-4相同的晶体结构的ZSM-4。令人惊奇地，由其制备的催化剂比由先前方法制备的ZSM-4制备的催化剂更加稳定。
