The Cheap Oxalic acid CAS 6153-56-6 is a white, transparent crystal that loses its crystallization water and transforms into anhydrous oxalic acid when heated to 100.1°C. It is easily soluble in water and ethanol, slightly soluble in ether, and insoluble in benzene and chloroform, with hygroscopic properties.
In the industrial sector, oxalic acid is commonly used as a rust remover and can also be used to remove ink stains from white clothing. Through thermal decomposition, it can be utilized to produce carbon monoxide gas. Additionally, oxalic acid is a key pharmaceutical intermediate and an important raw material in the leather and rare earth industries.
