Multifunctional dithiodialkanoamidophenol compounds useful in the stabilization of organic materials normally susceptible to oxidative degradation are prepared by contacting a selected dithiodialkanoic acid chloride with a selected alkylaminophenol under amide-forming reaction conditions. In a preferred embodiment, the compound is N,N'-bis(3',5'-di-t-butyl-4'-hydroxyphenyl)-3,4-dithiahexane-1,6-dicarboxamide.
在酰胺化反应条件下,将选定的二硫代二烷基氯化酸与选定的烷基氨基苯酚接触,可制备出有助于稳定通常易氧化降解的有机材料的多功能二硫代二烷基氨基苯酚化合物。在一个优选的实施方案中,该化合物是 N,N'-双(3',5'-二叔丁基-4'-羟基苯基)-3,4-二硫杂己烷-1,6-二甲酰胺。
