Preparation and characterization of long-chain di-n-alkyl disulfides

Article abstract of DOI:10.1080/10426509808545451

The preparation of long-chain symmetric di-n-alkyl disulfides based on the reaction of BUNTE SALTS (RS₂O₃Na) with iodine is reported. ¹H-NMR, FT-IR, and FT-RAMAN spectra of the solid and liquid/molten aliphatic title disulfides were recorded. An assignment of the vibrational frequencies is proposed especially in regard to the S-S and C-S vibrations. Distinct spectral differences are determined between the solid and liquid state, as well as between disulfides with even and those with odd numbered alkyl substituents, respectively. The observed phenomena are ascribed to different species in the solids and liquids/melts and their respective VAN DER WAALS interactions. In addition, mass spectra, GC-MS studies, as well as the thermal behaviour of the disulfides, based on investigations by DSC and TGA, are reported.
