    摘要： The present invention relates to a process for removing acetylenes from olefins by using an ionic liquid-based solution, and particularly to a process for removing a small amount of acetylenes contained in olefins by using an ionic liquid-based solution where copper halide (CuX, X=halogen atom) is dissolved. In an ionic liquid-based solution used in the present invention, copper halide (CuX) is stabilized by ionic liquid, thus preventing monovalent copper ion (Cu+) from being oxidized into divalent copper ion (Cu2+), maintaining the superior activity of monovalent copper ion (Cu+) in removing acetylene for a long period of time, and remarkably increasing the selective removal of acetylene-based compounds. Moreover, an ionic liquid-based solution used in the present invention may serve as an extracting solution as well as an absorbent, thereby facilitating the operation and reducing equipment cost in comparison to the conventional extracting agent used in a slurry phase.

    摘要： Disclosed are a pyrrolidinium type sulphonated zwitterion, a method of preparing the same, a lithium salt prepared by using the same, a method of preparing the salt, an electrolytic composition containing the salt and a lithium secondary battery including the electrolytic composition. Since the pyrrolidinium type sulphonated zwitterions prepared according to the invention are thermally and electrochemically stable, the lithium salt prepared by using the same exhibits a lower hygroscopicity than the conventional lithium salts and strong thermal and electrochemical stabilities. When the lithium salt of the invention is dissolved in an organic solvent independently or together with the ionic liquid, excellent conductivity and electrochemical stability are exhibited. Accordingly, the lithium salt of the invention is very suitable for the electrolyte of the lithium secondary battery.
