Title:
Carboxylic acid recovery from a magnesium carboxylate mixture
Document Type and Number:
Japanese Patent JP6046242
Kind Code:
B2
Abstract:
The invention is directed to a method for recovering carboyxlic acid from an magnesium carboxylate containing aqueous mixture comprising, comprising the steps of
- contacting the aqueous mixture with an acidic ion exchanger, thereby forming a carboxylic acid mixture and an ion exchanger loaded with magnesium ions; and
- contacting the ion exchanger loaded with magnesium ions with a hydrochloric acid solution, thereby forming a magnesium chloride solution; and
- thermally decomposing the magnesium chloride solution at a temperature of at least 300 °C, thereby forming magnesium oxide (MgO) and hydrogen chloride (HCl).
