method for isolating carboxylic acid from aqueous solution |
| abstract |
Patent specification: "Method for isolating carboxylic acid from aqueous solution". The present invention relates to a method for the manufacture of carboxylic acid which comprises the steps of subjecting an aqueous mixture comprising carboxylic acid and at least 5% by weight of dissolved magnesium chloride to a direct extraction step using a first liquid. An organic solvent comprising an organic solvent, obtaining its organic carboxylic acid solution and an aqueous residual liquid comprising magnesium chloride, subjecting the organic carboxylic acid solution to a back extraction step, obtaining its aqueous carboxylic acid solution and a second organic liquid. subjecting the aqueous residual liquid comprising magnesium chloride derived from direct extraction to a thermal decomposition step at a temperature of at least 300 ° C, decomposing the magnesium chloride into magnesium oxide and hcl. Selecting the specific c5 + ketone solvent provides the manufacture of a high purity product and an effective and suitable hse thermal decomposition step. 1/47 21581233v1 4/4 1/4 1/1 1/1 |
