Novel α-aminoacetamides are powerful stabilizers for organic materials subject to oxygen and heat degradation, and particularly for synthetic natural rubber, synthetic ester lubricants and synthetic resinous materials. A wide range of substituents on the amine and amide N atoms, at least one of which substituents is an alkylene imine (cyclic), and an even wider range of substituents on the saturated carbon atom, yields an array of stabilizers having a wide range of compatibility in compositions comprising various synthetic resinous compounds to be stabilized.
Novel syntheses are provided utilizing at least one amine nucleophilic agent, a trichloromethide ion generating agent, and an alkoxide ion generating agent, which together in the presence of aqueous alkali and an onium salt, yield novel a-aminoacetamides in which a wide choice of substituents may be introduced. The nucleophilic agent may be a primary or secondary amine, or one of each. The trichloromethide ion generating agent is a haloform. The alkoxide ion generating agent may be a ketone, or an aldehyde which reacts with the haloform.

新型 α-氨基乙酰胺是一种强力稳定剂,适用于受氧和热降解的有机材料,尤其适用于合成天然橡胶、合成酯润滑剂和合成树脂材料。胺和酰胺 N 原子上的取代基范围很广,其中至少有一个取代基是亚烷基亚胺(环状),而饱和碳原子上的取代基范围则更广,从而产生了一系列稳定剂,这些稳定剂在由各种待稳定的合成树脂化合物组成的组合物中具有广泛的兼容性。
提供了新颖的合成方法,利用至少一种胺类亲核剂、一种三氯甲烷离子生成剂和一种烷氧基离子生成剂,在水碱和鎓盐的存在下共同生成新颖的 a-氨基乙酰胺,其中可引入多种取代基。亲核剂可以是伯胺或仲胺,或两者之一。三氯甲烷离子发生剂为卤代甲烷。氧化烷离子生成剂可以是与卤代甲烷反应的酮或醛。
