  • CONTINUOUS ION EXCHANGE AND ESTERIFICATION OF FERMENTED MALONIC ACID
    Publication number: 20250269366
    Abstract: Provided herein is a process of ion exchange comprising malonic acid or a salt thereof and a cation or an anion cation exchange resin. The ion exchange is accomplished, e.g., and without limitation by continuous ion exchange. A valve and resin bed configuration is useful in this regard.
