Abstract

The oxo-diperoxo molybdenum(VI) complex MoO(O(2))(2).2QOH (QOH = 8-quinilinol) was prepared and characterized by elemental analysis, IR and UV-Vis spectra. The ionic liquids (ILs) [bmim][BF(4)], [hydemim][BF(4)], and [bmim][PF(6)] were characterized by (1)H-NMR and UV-Vis spectra. The epoxidation of a technical mixture of methyl oleate and methyl linoleate with H(2)O(2), in [bmim][BF(4)], [hydemim][BF(4)] and [bmim][PF(6)], catalyzed by MoO(O(2))(2).2QOH (QOH = 8-quinilinol) and with NaHCO(3) as co-catalyst has been studied for the first time. It was found that high conversions of methyl oleate and methyl linoleate to their respective oxidation products, as well as the total selectivity of their oxidation products to oxirane in [hydemim][BF(4)] were obtained. Also, the IL phases containing the Mo(VI) catalyst can be readily recycled by washing with diethyl ether and drying, and the Mo(VI) catalyst can be reused at least five times.

摘要

制备了氧代-双过氧钼(VI)配合物MoO(O₂)₂·2QOH（QOH = 8-喹啉醇），并通过元素分析、红外光谱和紫外可见光谱对其进行了表征。离子液体（ILs）[bmim][BF₄]、[hydemim][BF₄]和[bmim][PF₆]通过¹H-NMR和紫外可见光谱进行了表征。首次研究了在[bmim][BF₄]、[hydemim][BF₄]和[bmim][PF₆]中，以MoO(O₂)₂·2QOH（QOH = 8-喹啉醇）为催化剂、NaHCO₃为助催化剂，用过氧化氢对油酸甲酯和亚油酸甲酯的工业混合物进行环氧化反应。结果发现，在[hydemim][BF₄]中，油酸甲酯和亚油酸甲酯能高转化率地转化为各自的氧化产物，并且其氧化产物对环氧乙烷的总选择性也较高。此外，含有Mo(VI)催化剂的离子液体相通过用乙醚洗涤和干燥可以很容易地循环利用，Mo(VI)催化剂至少可以重复使用五次。
