There are provided phenolic antioxidant hydrazides of the formula
wherein
R¹ is a tertiary alkyl of 4 to 8 carbons,
R² is, e.g., hydrogen or t-alkyl of 4 to 8 carbons,
R³, R⁴, R⁵, R⁶, and R⁷ are independently selected from hydrogen, alkyl of 1 to 6 carbons, and phenyl,
y is an integer of from 0 to 6, and
z is an integer of from 0 to 10,
which are useful to stabilize organic materials (such as synthetic polymers) which are subject to oxidative degradation.
提供了式中的酚类抗氧化剂酰肼
其中
R¹ 是碳原子数为 4 至 8 的叔烷基、
R² 是氢或 4 至 8 个碳原子的叔烷基、
R³、R⁴、R⁵、R⁶ 和 R⁷ 独立选自氢、1-6 碳原子的烷基和苯基、
y 是 0 到 6 的整数,和
z 是 0 至 10 的整数、
这些化合物可用于稳定易氧化降解的有机材料(如合成聚合物)。
