潤滑再生油의 酸化安定性能 (第2報). 抗酸化性 物質의 生成

Oxidation Stability of Regenerated Lubricating Oils (II) Formation of anti-Oxidant Materials

潤滑再生油의 酸化安定性이 向上되는 機構를 알기 爲하여 第一報에서 만든 試料와 輕油을 混合한 것과 輕油에다 添加劑(알킬벤젠과 페놀형물질)를 混合한 試料의 酸化安定性能 試驗을 하여 內然機關에서 使用한 潤滑廢油의 再生油가 酸化安定性이 向上되었음을 알았고 使用途中 芳香族化合物, 特히 페놀型 有機物의 生成에 基因한다는 結論을 얻었다.

The oxidation stability of samples prepared by blending samples reported previously with diesel oil and diesel oil with additives(alkyl benzene and phenolic type of materials), was tested to study the mechanism of thermal oxidation stability of the regenerated lubricating oils. It was found that the improvement of thermal oxidation stability of such oils was caused by the formation of aromatic compounds, especially phenolic type of organic materials.
