AbstractThe catalytic properties of samples of amorphous mesoporous aluminosilicate ASM with different Si/Al molar ratios (40, 80, 160) were studied in the synthesis of practically important pyridines (by the interaction of С2–С5 alcohols with formaldehyde and ammonia, cyclocondensation of acetaldehyde and propionic aldehyde with ammonia), dialkylquinolines and alkyltetrahydroquinolines (by reaction
摘要具有不同的Si / Al摩尔比(40,80,160)的无定形硅铝酸盐介孔ASM的样品的催化性能在实际上重要的吡啶类合成进行了研究(由С的相互作用2个-С 5醇与甲醛和氨,环化缩合乙醛和丙醛与氨的混合物),二烷基喹啉和烷基四氢喹啉(通过苯胺与C 3,C 4醛的反应)和烷基二氢喹啉(通过苯胺与酮,丙酮和苯乙酮的相互作用)。发现在所研究的样品中具有最高酸度的Si / Al = 40的摩尔比的中孔铝硅酸盐ASM样品在这些反应中表现出最高的活性和选择性。

AbstractThe catalytic properties of microporous zeolites of different structural types (FAU, BEA, MOR, and MFI), a micro–meso–macroporous zeolite (H-Ymmm), and an ASM mesoporous aluminosilicate in the reaction of aniline with propionic aldehyde have been studied. It has been found that the reaction proceeds with a high conversion of aniline (90–99% over zeolites and 71% over an ASM aluminosilicate) to form

Abstract The catalytic properties of a microporous H-ZSM-5 zeolite and a granular hierarchical H-ZSM-5h zeolite in the synthesis of basic pyridines and quinolines have been studied. A specific feature of zeolite H-ZSM-5h is the absence of a binder in the granules and the presence of micro-, meso-, and macropores in the pore structure. The H-ZSM-5h sample comprises, in addition to crystals of the original

NiO/Na–Yh, Co3O4/Na–Yh, and CuO/Na–Yh) in the synthesis of quinolines from aniline and n-propanol. The highest aniline conversion and highest total quinoline selectivity (49 and 63%, respectively) were achieved in the presence of the ZnO/Na–Yh sample. The samples promoted with Ni, Co, and Cu oxides reached a twofold lower aniline conversion (20–26%) with quinoline selectivity of 42–51%.
摘要 该研究调查了用金属氧化物(指定为 ZnO/Na–Y h、NiO/Na–Y h、Co 3 O 4 / Na–Y h和 CuO/Na– Y h ) 从苯胺和正丙醇合成喹啉。在 ZnO/Na-Y h样品存在的情况下,实现了最高的苯胺转化率和最高的总喹啉选择性(分别为 49% 和 63%)。用 Ni、Co 和 Cu 氧化物促进的样品达到低两倍的苯胺转化率 (20-26%),喹啉选择性为 42-51%。
