Investigation of interaction of zinc dithiophosphates with tetraethylenepentamine by NMR method

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

Summary

  1. 1.

    On the basis of an analysis of NMR spectra, the hypothesis is advanced that the interaction between a zinc dithiophosphate and tetraethylenepentamine (the latter compound modeling the amine grouping of succinimide additives) is accompanied by the formation of hydrogen bonds involving the amine protons, and is determined mainly by the electron-donor properties of the zinc dithiophosphate molecule.

  2. 2.

    The interaction of tetraethylenepentamine with a zinc dialkyldithiophosphate (according to information from NMR spectra) is more vigorous than with a zinc diaryldithiophosphate.

  3. 3.

    From the results obtained in this study, it may be assumed that greater synergistic effects in solubilization will be shown by those additive packages in which the molecular interaction between the components is the more vigorous.
