The issue of selecting antioxidants for gasoline
Thread Content
I’d like to ask everyone: are antioxidants still added to gasoline produced these days? What type is generally added? Is the use of phenolic antioxidants widespread? Recently, I have been studying the Drabkin test method for the determination of thiol compounds. The national standards state that when phenolic substances are present in trace amounts or more, it can affect the results of the Drabkin test. I’m not sure if it has an impact on the use of phenolic antioxidants? Thank you all!
Gasoline produced by refineries these days does not contain antioxidants, but it still evaporates and oxidizes when exposed to air for an extended period of time. :)
:Oh, thank you. There’s no need to add anything now; I thought it was still necessary to do so
Dienes in gasoline are the reason for the low induction period of gasoline; nowadays, hydrogenation is applied to catalytic gasoline in order to first remove these dienes, and therefore antioxidants are no longer necessary.
:handshake thank you
