| 摘 要： | 以乙二胺(EDA)为模板剂,采用原位固相转化法合成了ZSM-35沸石,并通过XRD对沸石晶化过程中的影响因素和晶化机理作了详细考察。结果表明,制备ZSM-35沸石适宜的硅铝摩尔比为21n(SiO2)/n(Al2O3)37;Na+与模板剂EDA协同作用,共同对ZSM-35沸石起着结构导向作用;延长晶化时间,ZSM-35沸石容易向ZSM-5沸石转晶,合成ZSM-35沸石合适的晶化时间为14～21 h。对晶化机理的考察表明ZSM-35沸石的合成过程具有固相机理的特征,并且由于ZSM-35沸石与ZSM-5沸石具有相同的次级结构单元,在晶化过程中容易发生转晶。 |

| Abstract: | Using ethylenediamine(EDA) as template agent,ZSM-35 zeolite was prepared by in-situ solid phase transformation method.The influences on crystallization process as well as crystallization mechanism were investigated in detail by XRD method.Results showed that the proper silicon-aluminum molar ratio n(SiO2)/n(Al2O3) for synthesis of ZSM-35 zeolite is 21～37;both Na+ and EDA play a cooperative structure-orientation role in the synthesis of ZSM-35 zeolite;suitable time for crystallization is 14～21 h,while extension of crystallization time tends to change ZSM-35 zeolite into ZSM-5 zeolite.Results of study on crystallization mechanism indicated that the synthesis process displays features of solid phase crystallization mechanism.Since both ZSM-35 zeolite and ZSM-5 zeolite have same secondary structural units,they are easily to transform each other in the crystallization process. |
