Petroleum sulfonic acids

For example, treating petroleum distillates with sulfuric acid is generally applied to dissolve unstable or colored substances and sulfur compounds as well as to precipitate asphaltic materials. When drastic conditions are employed, as in the treatment of lubricating fractions with large amounts of concentrated acid or when fuming acid is used in the manufacture of white oils, considerable quantities of petroleum sulfonic acids are formed ... 

Petroleum sulfonic acids may be divided roughly into those soluble in hydrocarbons and those solnble in water. Because of their color, hydrocarbon-soluble acids are referred to as mahogany acids, and the water-soluble acids are referred to as green acids. The composition of each type varies with the nature of the oil sulfonated and the concentration of acids produced. In general, those formed during light acid treatment are water soluble oil-soluble acids result from more drastic sulfonation. 

J-F. Wilson, USP 3223185(1965) CA 64, 6153(1966) [The instability of AN (used in expls and fertilizers) in storage results from change in water content or changes in vol at the phase transition points. The improvement in stability is achieved by coating the AN particles with a compn consisting of a major amt of a clay (such as attapulgite, kaolin or diatomaceous earth), and a minor amt of an oil-sol alk-earth metal salt of petroleum sulfonic acids (sucb as Ca petroleum sulfonate)]...

Overbase magnesium sulfonates are a transparent colloidal dispersion (0.1 xm or smaller) of magnesium carbonate in oil containing protective colloids, which are usually magnesium derivatives of petroleum sulfonic acids or alkyl benzene sulfonic acids. 

White oils are prepared by drastic further treatment of lubricant stocks. In the older process the appropriate stock was subjected to successive treatments with sulfuric acid until the refined oil met the desired specifications. Acid-treatment is still used to refine white oils because the other products of the process, mahogany petroleum sulfonic acids, are valuable and useful in their own right. The modern process for making white oils utilizes a severe double hydrogenation followed by clay bleaching.

Fatty amines and diamines can be used for corrosion inhibition in oil-producing wells. Typically, these products are dispersed as salts of organic acids such as fatty acids or petroleum sulfonic acids. Fatty amines and diamines have also been used as corrosion inhibitors in the transportation and storage of petroleum products. Quaternary ammonium salts, including dialkyldimethy-lammonium, monoalkyltrimethylammonium and mono-alkyldimethylbenzylammonium, are good corrosion inhibitors.
