摘要： As synthesized by conventional technique, zeolite ZSM-5 is crystallized in the presence of substantial amount of tetraalkylammonium cations, the alkyl groups of which contain 2 to 5 carbon atoms, such as, for example, tetrapropylammonium. When synthesized in the conventional way, ZSM-5 contains tetraalkylammonium cations as well as a substantial amount of sodium ions. To obtain a more catalytically active form of ZSM-5, the sodium ions must be exchanged to very low levels. By synthesizing zeolite ZSM-5 according to the present method, i.e., in the presence of a combination of an amine and a halide in the presence of a mutual solvent and with a specifically defined reaction mixture composition, ZSM-5 having different organic nitrogen-containing cations but the same crystal structure as conventionally prepared ZSM-5 is obtained. The ZSM-5 prepared in accordance herewith is very low in sodium content as synthesized and has a crystal size of from about 0.05 microns to about 20 microns.
摘要翻译：如通过常规技术合成的，沸石ZSM-5在存在大量四烷基铵阳离子（其烷基含有2至5个碳原子的四烷基铵阳离子）存在下结晶，例如四丙基铵。当以常规方式合成时，ZSM-5含有四烷基铵阳离子以及大量的钠离子。为了获得更具催化活性的ZSM-5形式，钠离子必须交换到非常低的水平。通过根据本发明的方法合成沸石ZSM-5，即在相互溶剂存在下，在胺和卤化物的组合存在下，与特定定义的反应混合物组合物，具有不同有机氮气的ZSM-5，得到与常规制备的ZSM-5相同的晶体结构。根据本文制备的ZSM-5的钠含量非常低，并且具有约0.05微米至约20微米的晶体尺寸。
