Potentiometric titration of diesel oils
The potentiometric titration procedure has been expanded and its accuracy increased to suit actual conditions of oil performance in diesel engines.
It has been shown that it is necessary to determine the base number at pH 2, besides the total base number, to characterize the neutralizing capacity of oils.
A graphical treatment of experimental data has been suggested which allows the determination of a co-efficient characterizing the consumption rate of basic additive components.
It has been shown that the additive VNII NP-350 has two titration steps; according to its degree of activity the barium present in the oil can be separated into “active” and “titratable” barium.
