Synthesis, Thermal Stability, and Colloid-Chemical Properties of Pyridinium Ionic Liquids with the Bromotrichloroferrate Anion
Ionic liquids were synthesized: 1-alkylpyridinium bromotrichloroferrates(III) [C5H5N–R]FeCl3Br, where R = H, C2H5, C4H9, C6H13, C8H17, C10H21, C12H25, or C16H33. All compounds were characterized by IR and visible spectroscopy data. Their thermal stability in air was studied in the temperature range of 25–600°C, as well as the thermal stability of 1-alkylpyridinium bromides. The influence of the alkyl chain length in the cation and the nature of the anion on the thermal stability of ionic liquids was established. A comparative analysis of the thermal stability of 1-alkylpyridinium bromides and bromotrichloroferrates was carried out. For ionic liquids with long-chain radicals, the critical micelle concentration was determined by conductometry. Surface tension isotherms were obtained and the main colloid-chemical properties were calculated.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
