Crystal formation inhibition in lubricating compositions |
摘要 |
Lubricating oil formulations comprising base oil, sulfur-phosphorous anti-wear/extreme pressure agents and hindered phenol antioxidants which anti-wear/extreme-pressure agents and hindered phenolic antioxidants are prone to crystal formation wherein the base oil is characterized as having a saturates content of less than 99% are stabilized against crystal formation by the addition of a minor amount of a high molecular weight di- or polycarboxylic acid anhydride, or mixture thereof.
