Rapid method of determination of chlorine in additives and in additive oils

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    A rapid method has been developed for the determination of chlorine in additives and in additive oils. The method is based on oxidation of the chlorine-containing additives in an oxygen atmosphere, with subsequent titration of the chlorine solution with acidic mercuric nitrate in the presence of diphenylcarbazone indicator.

  2. 2.

    The proposed method may be used for the analysis of diesel fuels, greases, and other petroleum products with chlorine-containing additives.

  3. 3.

    Checks of this method on artificial blends showed good repeatability; the sensitivity of the method is 10−2. The time required for analysis does not exceed 30 min, whereas the time for a determination by GOST 9427-60 requires about 2 h.
