摘要： 合成了一种烷基化N-苯基-α-萘胺高温抗氧剂，采用红外光谱、气相色谱等手段表征该抗氧剂结构和纯度，并用加压差示扫描量热法（PDSC）和烘箱氧化法考察了其在基础油（酯）中的抗氧化性能；进而对合成抗氧剂在航空发动机油、SM规格汽油机油中的性能进行评价。结果表明，烷基化N-苯基-α-萘胺高温抗氧剂具有较高的热分解温度和氧化安定性，具有比常规抗氧剂更突出的抗氧化性能，能满足油品在高温工况下抗氧性能要求。

Abstract: A high temperature antioxidant,alkylated N-phenyl-α-naphthylamine,was successfully synthesized in laboratory. The structure and purity of the antioxidant were characterized by IR,MS and GC. The oxidation resistance of the antioxidant in base oil was investigated by means of pressure differential scanning calorimetry (PDSC) and oven oxidation method. The antioxidant performance in aviation engine oil and SM specification gasoline engine oil was also evaluated. The results show that alkylated N-phenyl-α-naphthylamine has higher thermal decomposition temperature and oxidation stability, compared with the conventional antioxidant, which can meet the requirement of antioxidants in high temperature environment.
Key words: lubricating oil, antioxidant, oxidation stability, amine type, aviation engine oil
