Web11 mei 2024 · A key characteristic of ionic liquids is that they exist in the liquid phase, which is different from many of the traditional salts you’d encounter in a typical chemistry lab. Those salts, like NaCl or KCl, are solid at room temperature and only melt at extremely high temperatures. At these temperatures (800.7 °C for NaCl, 770 °C for KCl) 1 ... WebSelective PILs were synthetized from the [VC6IM][Cl], [VC16IM][Br], and [(VIM)(2)C-10]2 [Br] - ionic liquids -by in-situ thermal-initiated polymerization in a fused silica capillary column for in-tube SPME. The synthesis procedure was optimized, and the capillary columns were characterized using spectroscopic and chromatography techniques. Compared with CHP, most ionic liquids had significantly higher thermal stability. Ionic liquids refer to salts composed of anions and cations that were liquid at room temperature or slightly higher than room temperature. Therefore, ionic liquids were often called specific classes of salts room temperature … Meer weergeven The thermogravimetric experimental results for the considered samples were represented and compared by using thermogravimetric (TG) curves.
