采用气相色谱质谱联用法测定变压器油、汽轮机油中的苯酚类抗氧化剂含量,包括2,6-二叔丁基对甲苯酚（简称T501）和2,6-二叔丁基苯酚,建立了变压器油、汽轮机油中苯酚类抗氧化剂的定量检测方法,包括萃取进样法和直接进样法。结果表明：萃取进样法和直接进样法均可用于变压器油、汽轮机油中苯酚类抗氧化剂的定量检测,突破了现有标准只能检测T501一种抗氧化剂的局限,建立了利用气质联用仪检测变压器油、汽轮机油中两种常见酚类抗氧化剂含量的方法,为变压器油、汽轮机油中有机小分子的高效检测提供了新方法和新思路。

The phenolic antioxidant content in transformer oil or turbine oil, including 2,6-di-tert-butyl-para cresol （T501） and 2,6-di-tert-butylphenol, was detected by gas chromatography-mass spectrometer （GC-MS）. The quantitative determination methods, including liquid-liquid extraction method and direct injection method, were established. The results show that the liquid-liquid extraction method and direct injection method both can be applied in the detection of phenolic antioxidant content in transformer oil or turbine oil, breaking the limitati...
