PROCESS FOR PURIFYING CARBOXYLIC ACIDS |
abstract |
Polycarboxylic acids are purified by contacting a crude polycarboxylic acid with a solvent to produce a substantially pure polycarboxylic acid. The solvent is chosen so that the impurities are soluble in the solvent and the polycarboxylic acid is insoluble in the solvent. |
