<p>Process for recovering acetic acids from waste water, characterized by the fact that these are extracted in counterflow with ethylacetate or methylisobutylketone, which are removed in the aqueous phase of dissolved solvent constituents by azeotropic distillation and the organic phases are subjected to azeotropic, fractional distillation. In addition, the invention concerns devices for carrying out this process.</p> |
