New antioxidant additives

Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    It has been established that pyrazolidone derivatives are transformer oil oxidation inhibitors. The effectiveness of their action depends on molecular structure. The most active antioxidant additives proved to be derivatives containing phenyl radicals in the 1 or 5 positions.

  2. 2.

    It has been shown thatgb-hydrazinopropionic acid derivatives also display inhibiting action with respect to transformer oil

  3. 3.

    The corrosiveness of transformer oil with respect to copper, steel, and lead in the presence of these additives has been investigated.

  4. 4.

    It has been found that derivatives of pyrazolidone or ofβ-hydrazinopropionic acid effectively retard the oxidation of naphthenoparaffinic hydrocarbons.
