This is the first report of an innovative, one-pot, pseudo-five-component, and solvent-free synthesis of 6,6′-(arylmethylene)bis(2-(tert-butyl)4-methylphenol) antioxidants from p-cresol, methyl tert-butyl ether, and aldehydes in the presence of sulfonated multi-walled carbon nanotubes (MWCNTs-SO3H) as heterogeneous, robust, and reusable catalysts under solvent-free conditions. MWCNTs-SO3H was prepared
这是第一篇关于从 p- 合成 6,6'-(芳基亚甲基)双(2-(叔丁基)4-甲基苯酚)抗氧化剂的创新、单锅、伪五组分和无溶剂合成报告。在磺化多壁碳纳米管 (MWCNTs-SO3H) 存在下,甲酚、甲基叔丁基醚和醛作为无溶剂条件下的多相、坚固且可重复使用的催化剂。MWCNTs-SO3H 是通过一些显微和光谱技术制备和表征的,包括扫描电子显微镜、透射电子显微镜、傅里叶变换红外光谱、拉曼光谱、在不同溶剂中的分散性和热重分析(每大约五个碳原子一个功能)。催化剂的酸度通过酸碱滴定法 (1.80 mmol g-1) 测量。该反应顺利进行,以良好的收率得到产物。该催化剂可重复使用多次而没有有效损失其用于制备 6,6'-(芳基亚甲基)双(2-(叔丁基)...
