Benefits of antioxidants in lubricants and greases
The long‐term thermo‐oxidative stability of lubricants and greases is a prerequisite to meet today's ‘stay in grade’ and extended drain interval requirements. To achieve this goal, there is a need for a better understanding of thermo‐oxidative lubricant degradation and of how antioxidants can affect this process.

Maximizing the Reactivity of Phenolic and Aminic Radical
ConspectusHydrocarbon autoxidation, the archetype free radical chain reaction, challenges the longevity of both living organisms and petroleum-derived products. The most important strategy in slowing this process is via the intervention of radical-trapping antioxidants (RTAs), which are abundant in nature and included as additives to almost every petroleum-derived product as well as several ...

The Chemistry of Radical Scavenging Antioxidants
In this study, the autoxidation of squalane inhibited by phenolic and aminic antioxidants was analysed between 160 and 220 °C representing piston assembly temperatures of automotive engines. The mechanism of the phenolic antioxidant octadecyl 3-(3,5-di-tert-butyl-4- hydroxyphenyl) (OHPP) in the presence of oxygen at these temperatures was analysed.

What are Phenolic Antioxidants? (with pictures)
Phenolic antioxidants are a class of protective chemical compounds that are found in plant foods.Since these protective chemicals only exist in plant-based foods, phenolic antioxidants are also called phytochemicals; the prefix “phyto” is the Latin word for “plant.”
