The Possibility to Obtain a New Generation of Ionic Liquids Starting From Natural Compounds,perties, ILs have been proposed as alternative solvents. Structurally, most of the ILs that have been investigated to date are based on imidazolium, pyridinium and ammonium cations, associated with polyatomic anions such as chloroaluminates, tetrafluoroborate, hexafluorophoshate and bis-triflimide. 作者: NATAL 時間: 2025-3-22 08:55
