| titleOfInvention | A kind of separation method of benzene polycarboxylic acid's isomers |
| abstract | The present invention relates to a kind of separation method of benzene polycarboxylic acid's isomers, the method comprises: in the solution of benzene polycarboxylic acid's isomers, add quaternary ammonium salt, stir, the one in quaternary ammonium salt and described benzene polycarboxylic acid's isomers is interacted, to form eutectic mixture; The eutectic mixture of formation is filtered; Eutectic mixture after filtering is dried, to remove solvent residual in eutectic mixture; Eutectic mixture after drying mix with counter solvent, stirs, filtration, obtain containing the one in the counter solvent of quaternary ammonium salt and described benzene polycarboxylic acid's isomers; Counter solvent containing quaternary ammonium salt is distilled, reclaims counter solvent and quaternary ammonium salt. |
