activity of the Fe3O4@SiO2-TETA-SO3H nanoparticles as a catalyst was investigated for benign one-pot synthesis of somenew amidoalkyl naphthols using fatty acids as bio-based resources. This reaction afforded the desired products within short reaction times, high yields and easy work-up procedure. This acidic catalyst could be recycled and reused for six runs without significant change in its activity. Furthermore
通过稳定二氧化硅包覆的Fe 3 O 4纳米粒子表面的磺酸基团,合成了新型功能化二氧化硅包覆的Fe 3 O 4纳米粒子Fe 3 O 4 @SiO 2 -TETA-SO 3 H。这些纳米粒子的结构通过傅里叶变换红外光谱、X射线衍射、场发射扫描电子显微镜、热重分析和振动样品磁力计以及能量色散X射线光谱进行了表征。Fe 3 O 4 @SiO 2 -TETA-SO 3的活性以脂肪酸为生物基资源,研究了作为催化剂的 H 纳米颗粒用于一些新型酰胺烷基萘酚的良性一锅法合成。该反应在反应时间短、收率高和易于后处理过程中提供了所需的产物。这种酸性催化剂可以循环使用并重复使用六次,而其活性不会发生显着变化。此外,针对金黄色葡萄球菌(ATCC 25,923) 和大肠杆菌(ATCC 25,922) 细菌评估了合成的脂肪酰氨基烷基萘酚的生物活性。
