Abstract

The preparation of Marine Fish Scales (MFS) and its analog doped with NaNO 3 (NaNO 3 /MFS) as new catalysts was discussed in this work. Then, these materials were characterized by ATG/ATD, X-ray diffraction, SEM, EDX, and IR spectrophotometer. The MFSand NaNO 3 /MFS can be used as eco-friendly catalysts for the Knoevenagel condensation and led to the functionalized alkenes in high yields with short reaction time. The tests show that 100 mg is the optimum mass, as well as the suitable solvent, is ethanol for the condensation of Knoevenagel. These parameters led to excellent yields (between 87 % and 99 % using NaNO 3 /MFS). These catalysts can be also reused for several times.

以海洋鱼鳞为新型高效环保催化剂的Knoevenagel缩合法合成功能化烯烃
本文讨论了以NaNO3/MFS为新型催化剂制备海洋鱼鳞(MFS)及其类似物的方法。然后,用ATG/ATD、X射线衍射、SEM、EDX和IR分光光度计对这些材料进行了表征。MFSand-NaNO3/MFS可作为Knoevenagel缩合反应的环保催化剂,并在短反应时间内以高产率制备功能化烯烃。试验表明,100 mg是Knoevenagel缩合的最佳质量,并且合适的溶剂是乙醇。这些参数导致了优异的产率(使用NaNO3/MFS在87%和99%之间)。这些催化剂也可以重复使用多次。
