    • A lubricant oil composition having a synergistic oxidative stability is disclosed, the composition comprising at least one hindered phenolic antioxidant, at least one mono-boronated hindered phenolic antioxidant, at least one di-boronated hindered phenolic antioxidant, at least one alkylated diphenylamine and at least one organomolybdenum compound. The invention also provides a lubricating oil additive concentrate composition that imparts synergistic oxidative stability to a lubricant oil upon its addition, the concentrate composition comprising at least one hindered phenolic antioxidant, at least one mono-boronated hindered phenolic antioxidant, at least one di-boronated hindered phenolic antioxidant, at least one alkylated diphenylamine and at least one organomolybdenum compound. Further, the concentrate compositions of the present invention may also be prepared with a high concentration of hindered phenolic antioxidants without deleterious effects on viscosity or lubricant solubility.
    • 公开了具有协同氧化稳定性的润滑油组合物,该组合物包含至少一种受阻酚抗氧化剂,至少一种单硼化受阻酚抗氧化剂,至少一种二硼化受阻酚抗氧化剂,至少一种烷基化二苯胺和至少一种 一种有机钼化合物。 本发明还提供一种润滑油添加剂浓缩物组合物,其在添加时赋予润滑油的协同氧化稳定性,所述浓缩组合物包含至少一种受阻酚抗氧化剂,至少一种单硼化受阻酚抗氧化剂,至少一种二硼化 受阻酚抗氧化剂,至少一种烷基化二苯胺和至少一种有机钼化合物。 此外,本发明的浓缩组合物还可以用高浓度的受阻酚抗氧化剂制备,对粘度或润滑剂溶解度没有有害影响。
