    Abstract: Novel imidazolium [1,2a] pyridine (ImPr) based protic ionic liquids with thiolate/disulfide and different carboxylate anions have been synthesized and characterized by NMR, IR and Mass spectroscopy. Thermogravimetry analysis (TGA) has been done to investigate the thermal behavior of these protic ionic liquids. Their decomposition temperatures are determined in the range of 126-175°C except [ImPr][HSO4] which is most stable with decomposition temperature of 326°C. Differential Scanning Calorimetry (DSC) has been used to analyze phase behavior of these protic Ionic liquid. Glass transition temperature has been observed for all the synthesized PILs. Ionic conductivity of [Impr] [Pim] is measured at 25 °C, 58.6 µS/cm, which is a relatively good conductivity in comparison with imidazolium-based ionic liquids. All ionic liquids were synthesized using an environmentally friendly solvent free method.

    Abstract: Provided is a process for preparing thiophenol derivatives, using aromatic disulfide as a starting material, and inexpensive sodium bisulfite (NaHSO 3 ) as a reducing agent. The process can be carried out on an industrial scale at low production costs, secures advantageous reaction conditions by using a small amount of water- soluble alcohol solvent. Further, the process can maximize the purity of the products by inhibiting reverse oxidation of the final product by the action of sulfur dioxide (SO 2 ) produced during the preparation process, after solvent extraction of the starting materials present as impurities of the thiophenol derivatives.
