in-situ pyridine FT-IR spectroscopy, and elemental analysis. ZrTf/S was found to be a highly efficient and reusable solid acid catalyst for ring opening of epoxides with amines and alcohols and produced β-amino alcohols and β-alkoxy alcohols respectively under ambient reaction conditions. The ZrTf/S catalyst showed the highest activity, which was attributed to its high acidity compared with that of
摘要 通过简单的一锅两步合成方法合成了金属 (Al, Ti, Zr) 三氟甲磺酸盐接枝的介孔 SBA-15 (AlTf/S, TiTf/S, ZrTf/S) 样品作为廉价的固体酸材料。通过 X 射线衍射、N2 吸附、热重分析、傅里叶变换红外光谱 (FT-IR)、原位吡啶 FT-IR 光谱和元素分析对这些材料进行了表征。ZrTf/S 被发现是一种高效且可重复使用的固体酸催化剂,用于环氧化物与胺和醇的开环,并在环境反应条件下分别制备 β-氨基醇和 β-烷氧基醇。与含钛和铝的样品相比,ZrTf/S 催化剂表现出最高的活性,这归因于其高酸性。
