该研究由三部分组成.第一部分通过对天然丝光沸石(NaM)的改性—采用固相熔盐法、溶液法与强酸弱碱盐FeCl<,3>进行离子交换,制得具有选择性催化功能的FeM沸石分子筛,并采用电导率仪、酸度计、呆见光份光光度计以及原子吸收光谱,对活化后天然丝光沸石与不同浓度FeCl<,3>溶液进行离子交换反应的动态过程进行了研究.第二部分通过钾长石与CaCl<,2>、CaO+H<,2>SO<,4>、CaSO<,4>+H<,2>SO<,4>、CaCl<,2>+NaOH、CaCl<,2>+H<,2>SO<,4>、NaOH等反应探讨用钾长石制备与其同硅铝比的个仍较强催化功能的沸石分子筛的途径.在第一、二部分制得沸石分子筛的基础上,还对Fe<3+>改性后的FeM及钾长石制得的沸石分子筛催化甲苯环上选择性取代氯化反应进行了研究分析.
