Abstract:

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 dialkyldiaryldithiophosphate 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. Author
