出版：Energy Institute (formerly Institute of Petroleum)
專家解讀視頻
This method describes procedures for the determination of acidic or basic constituents in petroleum products and lubricants. The method resolves these constituents into groups having weak-acid, strong-acid, weak-base, and strong-base ionization properties, provided the dissociation constants of the more strongly acidic or basic compounds are at least 1000 times that of the next weaker groups.
