| titleOfInvention | Method for separating and purifying an aqueous mixture consisting of the main components acetic acid and formic acid |
| abstract | The present invention relates to a method for separating and purifying an aqueous mixture consisting of the main components acetic acid and formic acid and high-boiling substances by extraction with a solvent in a circulation system, wherein the raffinate stream is treated with water. Characterized by mixing with most of the water from a solvent stripper column (11) to remove the water. The extract stream is introduced into a solvent distillation column (8), where, in a first step, a mixture (A) containing a high proportion of solvent is separated off from the top and a mixture (B) containing formic acid, water and solvent. Separates from the side outlet and also separates the mixture (C) consisting of acetic acid and high-boiling substances. The mixture (B) is introduced into a formic acid distillation column (4) for further processing, and the mixture (C) is introduced into an acetic acid distillation column (5), and the purified acetic acid is then introduced into the acetic acid distillation column (5). ) In the top. Pure formic acid is isolated in the settling basin of the formic acid distillation column (4), and the mixture of solvent and water is extracted via the top, which is then separated from the mixture (A) by the extractor ( Return to 7) and introduce. |
