ZSM-5沸石分子筛是70年代初由美国Mobil公司最早开发的。由于它对烷基化、异构化、歧化、选择裂化和甲醇合成汽油等反应具有独特的催化性能,是目前被广泛重视的一种新型催化剂材料。自从它问世以来,很长一段时间内,认为有机胺是合成ZSM-... ZSM-5沸石分子筛是70年代初由美国Mobil公司最早开发的。由于它对烷基化、异构化、歧化、选择裂化和甲醇合成汽油等反应具有独特的催化性能,是目前被广泛重视的一种新型催化剂材料。自从它问世以来,很长一段时间内,认为有机胺是合成ZSM-5沸石分子筛的必不可少的原料。1977年Whittan等发表了用异丙醇等醇类合成ZSM-5分子筛之后,我们成功地用“乙醇、氨、导向剂法”,“乙醇法”和“只加导向剂法”合成了ZSM-5分子筛。本工作是在上一工作基础上. 展开更多

An open-framework zinc-cobalt phosphate CoZnPO4-V with 16-ring extra-large-pore channels has been obtained in the presence of chain-type polyamines as the structure directing agent (SDA). Its large single crystal suited for structure refinement has been prepared with the assistance of small organic amines. Single-crystal X-ray diffraction analysis has shown that CoZnPO4-V is a novel metal phosphate. It crystallizes in monoclinic space group P21/c (No. 14), with a = 31.936(3) , b = 8.3775(7) , c = 15.7874(13) , α = γ = 90°, β = 97.0530(10)°, V = 4191.8(6) 3, and Z = 4 with R1 = 0.0455,wR2 = 0.0869. Its three-dimensional framework can be considered as stacking from two-dimensional nets and one-dimensional units as linkers. Between the stacking nets and linkers are located extra-large channels with 16-ring apertures. 展开更多
