| titleOfInvention | Process for the separation and purification of an aqueous mixture comprising the main components acetic acid and formic acid |
| abstract | The invention relates to a process for the separation and purification of an aqueous mixture comprising the main components acetic acid, formic acid and high boilers by extraction with a solvent in a circulation process, which comprises feeding the raffinate stream containing a major part of the water to a solvent stripping column (11) for removal of the water and conveying the extract stream to a solvent distillation column (8) from which, in a first step, a mixture (A) comprising the major part of the solvent is separated off via the top and a mixture (B) comprising formic acid, water and solvent is separated off at a side offtake and a mixture (C) comprising acetic acid and high boilers is separated off via the bottom, and, for further processing, feeding the mixture (B) to a formic acid distillation column (4) and feeding the mixture (C) to an acetic acid distillation column (5), subsequently isolating the pure acetic acid at the top of the acetic acid distillation column (5), isolating the pure formic acid at the bottom of the formic acid distillation column (4) and at the top taking off a mixture of solvent and water which, together with the mixture (A) after separating off the water present, is recirculated to the extractor (7). |
