“…Much of the art of petroleum sulfonate manufacture is concerned with the correct choice of the base stock and its method of refining, and with procedures for separation of the product sulfonate from sludge and unreacted oil. Petroleum hydrocarbons differ from dodecylbenzene in not forming sulfonic anhydrides during S03 sulfonation (202).…”

“…Decahydronaphthalene (decalin) forms an unidentified sulfonate upon treatment with S03 vapor for 2 hours at 193°( 121), as does 12-methylperhydroretene ("abietane") at 0°in 3 hours in tetrachloroethane as reaction solvent (542). The reaction of S03 with alkanes and cycloalkanes has never been of preparative interest, but it is of practical importance as one factor in the formation of by-product sludge in the sulfonation of petroleum fractions (202).…”

“…Although the exact chemical composition of the derived sulfonates is not known, detailed study of the most important group-the so-called "mahogany" or oilsoluble materials-indicates (100) that they generally resemble the long-chain alkylated benzene sulfonates. Similar processes are applicable, including the use of S03 vapor, which has been employed in the laboratory (202) and on a commercial (273) scale, and the liquid SO2 solvent approach (133,248), which is also used commercially. The SO2 solvent procedure entails no solvent cost, since it is produced by side reactions during sulfonation.…”

Sodium and calcium petroleum sulphonates have been prepared by sulphuric acid treatment of the Egyptian Morgan 350-450 "C petroleum fraction. Extraction and purification of the sulphonates from the sulphonated oil and the residual acid sludge is described. Corrosion studies revealed that the sodium petroleum sulphonates are more effective as corrosion inhibitors than the calcium salts in a neutral as well as in an acid medium. A maximum inhibition efficiency of about 75% was obtained by the sodium salt in an acid and a neutral medium, while the rclevant value obtained by the calcium salt is 60 and 23% in an acid and a neutral medium respectively. It has been also found that both salts accelerated corrosion when used at relatively high concentration in a neutral medium. Results are discussed according to the current views of corrosion inhibition.
