    摘要: A method of treating a solvent in a wood processing operation is described. A first organic compound is extracted from an aqueous solution with a solvent. Then, the solvent is contacted with an alkali solution to remove a second organic compound from the solvent. For example, the first organic compound may be acetic acid and the second organic compound may be lignin. In another embodiment, a liquid-liquid extraction solvent used to extract acetic acid from an aqueous solution is rejuvenated by contacting the solvent with an alkali solution to remove a second organic compound from the solvent. The rejuvenated solvent is then recycled for further liquid-liquid extraction.
