Separation and Identification of Zinc Dialkyldithiophosphates by Partition Paper Chromatography

Journal of The Japan Petroleum Institute, 1966
The performance of zinc dialkyldithiophosphates as lubricating oil additives depends on their chemical structure, so increasing interest is being shown in the structural analysis of those compounds.This paper deals with the chromatographic separation and identification of zinc dialkyldithiophosphates having three to eight carbon atoms in the alkyl ...
