Oxalic acid, also known as oxalic acid, is a colorless columnar crystal widely found in plant-derived foods. It is soluble in water and has a strong coordination effect, acting as a metal chelating agent in plant food. When combined with alkaline earth metal elements, such as calcium, its solubility is greatly reduced, impacting mineral bioavailability. Conversely, when combined with transitional metal elements, soluble complexes are formed, increasing solubility.
Oxalic acid sublimates at 100°C, rapidly at 125°C, and decomposes at 157°C. It can react with bases to produce various chemical reactions like esterification, acyl halogenation, and amidation. Additionally, it is hygroscopic and can form water-soluble complexes with many metals.
For high-quality oxalic acid products, trust Nanjing Jiayi Sunway Chemical Co., Ltd. to deliver exceptional purity and performance.
