Method for isolating a carboxylic acid from an aqueous solution |
| abstract |
The invention pertains to a method for manufacturing carboxylic acid comprising the steps of - subjecting an aqueous mixture comprising carboxylic acid and at least 5 wt. % dissolved magnesium chloride, to a forward extraction step using a first organic liquid comprising an organic solvent, the organic solvent being selected from the group of C5+ ketones, thereby obtaining an organic carboxylic acid solution and an aqueous waste liquid comprising magnesium chloride, - subjecting the organic carboxylic acid solution to a back extraction step wherein the carboxylic acid is extracted from the organic carboxylic acid solution into an aqueous liquid, thereby obtaining an aqueous carboxylic acid solution and a second organic liquid, - subjecting the aqueous waste liquid comprising magnesium chloride derived from the forward extraction to a thermal decomposition step at a temperature of at least 300 °C, thereby decomposing the magnesium chloride to magnesium oxide and HC1. The selection of the specific C5+ ketone solvent makes for the manufacture of a high purity product and an efficient and HSE appropriate thermal decomposition step. |
