Method for isolating a carboxylic acid from an aqueous solution |
| abstract |
The present invention relates to a process for the preparation of carboxylic acids, which comprises reacting an aqueous mixture comprising a carboxylic acid and at least 5% by weight of dissolved magnesium chloride with a first organic liquid comprising an organic solvent selected from the group of C5 + ketones Applying the organic carboxylic acid solution to a back extraction step to extract the carboxylic acid from the organic carboxylic acid solution into an aqueous liquid to obtain an aqueous carboxylic acid solution, And a second organic liquid; - applying the aqueous magnesium chloride-containing waste solution derived from the purified extraction to a thermal decomposition step at a temperature of at least 300 ° C to decompose the magnesium chloride into magnesium oxide and HCl . The selection of a particular C5 + ketone solvent contributes to the preparation of the high purity product and to the efficient and HSE-compatible thermal decomposition step. |
