Title: Process for purification of malonic acid from fermentation broth

Patent ·
OSTI ID:1892915
; ;

A process for the preparation of bio-based malonic acid and crystalline calcium malonate is provided. The calcium malonate is highly pure and provides a source of malonic acid made from a renewable carbon source rather than existing processes which rely on the use of petroleum-based products. The calcium malonate provides an improved source of malonic acid, which is important to many industrial processes.
