| 摘 要： | 利用微氧化装置考察了N-苯基-2-萘胺在菜籽油中的抗氧化性能以及不同金属对植物油及添加剂氧化聚合速率的影响。结果表明，铜对菜籽油的氧化聚合具有较强的催化作用，并且铜可引发N-苯基-2-萘胺的聚合反应，从而减弱了其抗氧化作用。

| Abstract: | The oxidative stability of rapeseed oil containing N-phenyl-2-naphthylamine (PAN) as an antioxidant was investigated on a micro-oxidation reactor equipped with various test cups.The effects of various metals on the oxidative stability and oxidation-induced polymerization rate of the rapeseed oil and the antioxidant were also examined on the same apparatus.It was found that the polymerization rate of oil is faster in the copper cup than that in the steel,aluminum,and glass cups.And because of the initiation function of the copper to the polymerization,the activity of PAN as an antioxidant is decreased greatly. |
