Patent number: 10618027Abstract: A method of decoloring an ionic liquid includes preparing a discolored ionic liquid, and decoloring the discolored ionic liquid through irradiation with UV rays. An ionic liquid that is discolored due to heat treatment upon purification is decolored and can thus be reused. The method of decoloring the ionic liquid is effective because an ionic liquid, which is discolored due to heat treatment upon purification, can be decolored in a simple manner and also because an ionic liquid, which is discolored and is thus difficult to apply to the purification of an organic material, can be decolored in a simple manner, and can thus be reused in the form of a high-purity ionic liquid.Type: GrantFiled: February 14, 2017Date of Patent: April 14, 2020Assignee: INDUSTRY-ACADEMIC COOPERATION FOUNDATION CHOSUN UNIVERSITYInventors: Dong-Chan Shin, Ki-Hyun Kim, Yong-Taeg Oh
