Oxalic acid
is the simplest dicarboxylic acid, also known as oxalic acid. It is a colorless transparent crystal at room temperature and usually contains two molecules of crystal water. When heated to 100.1°C, it loses crystal water and becomes anhydrous oxalic acid. Toxic and harmful to human body. It is hygroscopic, easily soluble in ethanol, soluble in water, and slightly soluble in ether. Insoluble in benzene and chloroform. Oxalic acid is easily oxidized into carbon dioxide and water by the action of oxidizing agents. Oxalic acid can be quantitatively oxidized by potassium permanganate in an acidic solution, reducing the potassium permanganate solution to divalent manganese and discoloring, and oxalic acid with crystal water is a crystal that is easy to purify. At 189.5°C or in case of concentrated sulfuric acid, it will decompose into carbon dioxide, carbon monoxide and water. Laboratory can use oxalic acid thermal decomposition to produce carbon monoxide gas. There is also a small amount of oxalic acid in human urine, and calcium oxalate is the main component of urethral stones.

Application
Application：
1、Mainly used as reducing agent and bleaching agent, mordant in printing and dyeing industry, also used for refining rare metals, synthesizing various oxalates, oxalates and oxamides, etc.
2、
used as analytical reagent
3、
Used as experimental reagents, chromatographic analysis reagents, dye intermediates and standard substances
4、
Oxalic acid is mainly used in the production of drugs such as antibiotics and borneol, as well as solvents for refining rare metals, dye reducing agents, and leather tanning agents. In addition, oxalic acid can also be used to synthesize various oxalate esters, oxalates and oxalamides, among which diethyl oxalate, sodium oxalate, and calcium oxalate are the most produced. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, metal and marble cleaning and textile bleaching
