(31)P-NMR analysis of zinc dialkyl(diaryl)-dithiophosphate in lubricating oil. Final report
Technical Report
·
OSTI ID:6020195
To assure that the oils furnished the government are of the same formulations as the oils originally qualified, a new method has been developed to examine zinc dialkyl(diaryl)dithiophosphate (ZDDP) additives by using P-NMR. Two finished oils and primary alkyl-ZDDP, secondary alkyl-ZDDP, and aryl-ZDDP were examined. P-NMR was found to be a better method than other existing analytical methods to analyze the change of ZDDP additives in full formulated oil without pre-separation.
