Action of Sulfuric Acid on Mercaptans

“…Previous Investigations Wood. Lowy, and Faragher (10) have studied the action of various refining agents upon petroleum solution of individual Thierry (8) has shown that a series of organic sulfides presumably present in a Persian distillate can be isolated by dilution of the acid tar formed during refining-a method used by Maberv and his collaborators (6) for investigating Ohio and Canadian petroleums. Neither Thierry nor Mabery seems to have contemplated the possible presence of disulfides or the possibility that the compounds originally in the distillate might undergo change during treatment with sulfuric acid.…”
