Ionic liquid functionalized acid orange for organic solvent and preparation method thereof

The invention relates to ionic liquid functionalized acid orange for an organic solvent and a preparation method thereof. The preparation method for the ionic liquid functionalized acid orange for theorganic solvent provided by the invention comprises the following steps: first, first, reacting triphenylphosphine and slightly excessive bromoalkane, and washing and purifying by using ethyl acetateto prepare alkyl triphenyl bromide; performing neutral reaction on acidified acid orange and silver carbonate, and washing and drying to prepare acid orange silver salt; then, respectively performingion exchange on the prepared acid orange silver salt and different alkyl triphenyl bromide to prepare a series of novel ionic liquid functionalized acid orange which can be dissolved in a plurality of organic solvents. The synthesis reaction conditions are mild and the post-treatment is simple. The type of ionic liquid functionalized acid orange has good solubility in the plurality of the organicsolvents, and is an azo dye
