Title: METHOD FOR DECOLORING IONIC LIQUID
Abstract:
The present invention relates to a method for decoloring an ionic liquid and, more specifically, to a method capable of decoloring and reusing an ionic liquid, which is discolored through heat treatment during purification. The method for decoloring an ionic liquid, of the present invention, has an effect of enabling an ionic liquid, which is discolored through heat treatment during purification, to be decolored by a simple method. In addition, the method for decoloring an ionic liquid, of the present invention, has an effect of decoloring an ionic liquid, which is discolored and difficult to be used in the purification of an organic material, through a simple method so as to be reusable as a high-purity ionic liquid.
