Avec la demande croissante de batteries électriques ces dernières années, l'acide oxalique, la principale matière première, a connu une augmentation de la demande et une augmentation de 60% du prix par rapport aux années 2020 bon marché, et les prix sont très volatils
Oxalic acid is a colorless columnar crystal, easily soluble in water but insoluble in organic solvents such as ether. Oxalic acid root has a strong coordination effect and is another type of metal chelator in plant source foods. When oxalic acid is combined with some alkaline earth metal elements, its solubility is greatly reduced, for example, calcium oxalate is almost insoluble in water. Thus the presence of oxalic acid has a great influence on the biological effectiveness of essential minerals; when oxalic acid is combined with some transition metal elements, its solubility is greatly increased due to the coordination of oxalic acid, which forms soluble complexes .
Oxalic acid starts to sublimate at 100°C, rapidly at 125°C, heavily at 157°C, and begins to decompose. It can react with bases and can undergo esterification, acylhalogenation, and amidation reactions. It can also undergo reduction reaction and decarboxylation reaction by heat. Oxalic acid anhydrous has hygroscopic properties. Oxalic acid can form water-soluble complexes with many metals.
