Abstract The study investigates the catalytic performance of microporous (H–Y) and micro–meso–macroporous (H–Yh, Fe2O3/H–Yh, PbO/H–Yh, and La–H–Yh ) FAU-type zeolites in the condensation of acetone with ammonia. In the presence of H–Yh, Fe2O3/H–Yh, and La–H–Yh, 2,4,6-trimethylpyridine was synthesized with selectivity of 54%, 58%, and 24%, respectively. In the presence of H–Y and PbO/H–Yh, the predominant
摘要 该研究研究了微孔(H-Y)和微中孔-大孔(H-Y h、Fe 2 O 3 /H-Y h、PbO/H-Y h和 La-H-Y h)的催化性能丙酮与氨缩合的FAU型沸石。在H-Y h、Fe 2 O 3 /H-Y h和La-H-Y h存在下,合成2,4,6-三甲基吡啶的选择性分别为54%、58%和24% . 在 H-Y 和 PbO/H-Y h存在下,主要反应是丙酮缩合反应,反应产物主要由双丙酮醇和异丙叉丙酮组成。
