  • Method of removing hydroperoxides from lubricating oils using sodium hydroxide and a metal thiophosphate
    Patent number: 5209839
    Abstract: NaOH can be used to remove hydroperoxides from a lubricating oil provided the oil contains a metal thiophosphate. This extends the useful life of the oil and the equipment being lubricated. In a preferred embodiment, the NaOH is immobilized within the lubrication system of an internal combustion engine.
