(57) [Problem] To concentrate an aromatic compound by adsorption without causing the target substance to remain contaminated by a solvent residue and not causing the target substance to react with a solvent and causing loss of yield. A method for separating and purifying a solution of an aromatic compound having an elastic modulus of 28 to 10 One or more times with an acidic zeolite having a molecular weight of 0.000 and after adsorption, the supernatant containing one or more unadsorbed compounds or, preferably, no compound, is separated off and adsorbed. Is desorbed from the adsorbent using a solvent. |
