ABSTRACT:
Sulfonic acids are converted into a hydrocarbon oil of superior oxidation stability by transforming the acids into compounds selected from the group consisting of ammonium sulfonates, substituted ammonium sulfonates, and sulfonic acid esters; and hydrotreating the resultant sulfonic acid derivatives at elevated temperatures in the presence of a hydrotreating catalyst. The hydrotreating process frees the parent hydrocarbons that originally constituted the organic portion of the sulfonic acids by cleaving the carbon-sulfur bond of the sulfonic acid derivatives. These parent hydrocarbons are recovered from the reaction products of the hydrotreating step and comprise a hydrocarbon oil that exhibits a higher stability toward oxidation than can otherwise be obtained from other hydrocarbon oils of similar composition and viscosity.
