Tunable properties prompt the development of different “tailor-made” functional ionic liquids (FILs) for specific tasks. FILs with an ether group are good solvents for many organic compounds and enzymic reactions. However, ionic composition influences the solubility by affecting the physiochem. properties of these FILs. To address the structure effect, a series of novel FILs with a mono-ether group (ME) based on imidazole were prepared through cationic functionalization and anionic exchange reactions, and characterized by NMR, mass spectroscopy, and Thermogravimetric anal. (TGA). The effect of ionic composition (cationic structure and anions) on d., viscosity, ionic conductivity, electrochem. window, and thermal properties of these ME-FILs were systematically investigated. In general, the viscosity and heat capacity increases with the bigger cationic volume of ME-FILs; in particular, the 2-alkyl substitution of imidazolium enhances the viscosity remarkably, whereas the d. and conductivity decrease on the condition of the same [NTf2]- anion; For these ME-FILs with the same cations, the d. follows the order of [NTf2]- > [PF6]- > [BF4]-. The viscosity follows the order of [PF6]- > [BF4]- > [NTf2]-. Ion conductivity follows the order of [NTf2]- ~[BF4]- > [PF6]-. It is noted that the dynamic d. has a good linear relationship with the temperature, and the slopes are the same for all ME-FILs. Furthermore, these ME-FILs have broad electrochem. windows and glass transition temperatures in addition to a cold crystallization and a melt temperature for ME-FIL7. Therefore, the cationic structure and counter anion affect the physicochem. properties of these ME-FILs together. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Application of 6294-17-3).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Application of 6294-17-3
