  Synthesis and Properties of Alkane-1,2-disulfonate Surfactants.

  摘要：

  Synthesis of pure alkane-1,2-disulfonic acids was accomplished by oxidation of the corresponding 1,2-dithiols or cyclic trithiocarbonates. The dithiols were obtained from the epoxides via the thiiranes, or by reacting the corresponding olefin with S2Cl2 and subsequent treatment with NaHS. The trithiocarbonates were prepared by reaction of the epoxides with potassium O-methyl dithiocarbonate. The disodium salts of the 1,2-disulfonic acids exhibited surfactant properties with critical micelle concentration (CMC) values between 10(-3) and 10(-4) M.
