    Notes: Conclusions 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. It has been shown thatgb-hydrazinopropionic acid derivatives also display inhibiting action with respect to transformer oil 3. The corrosiveness of transformer oil with respect to copper, steel, and lead in the presence of these additives has been investigated. 4. It has been found that derivatives of pyrazolidone or ofβ-hydrazinopropionic acid effectively retard the oxidation of naphthenoparaffinic hydrocarbons.

    Effect of complex esters derived from morpholinic alcohols on the oxidation of lubricating oils (1970)
    Springer
    Chemistry and technology of fuels and oils 6 (1970), S. 59-61

    Notes: Summary 1. A study has been made of the oxidation of industrial oil “12” and of a solution of polymethacrylate in it, and the effect of several new derivatives of morpholine containing two or three morpholine rings in the molecule. 2. It has been shown that complex esters of alcohols of the morpholine series with acetic, diphenyl acetic, and benzoic acids inhibit the oxidation of thickened oil and of base oil.
