Abstract
Processes for quantitating the corrosivity of naphthenic acids in a sample comprising crude oil or a liquid fraction thereof by reacting the sample with a metal comprising iron to produce iron naphthenates that are then stabilized by a ligand. The stabilized iron naphthenates are then analyzed by mass spectrometry to accurately quantitate the percentage of total naphthenic acids in the sample that are iron-reactive naphthenic acids associated with metal corrosion.
