Oxalic acid is mainly used in the production of antibiotics and borneo1 and other drugs, as well as solvents for extracting rare metals, dye reducing agents, tanning agents, etc. In addition, oxalic acid can also be used to synthesize various products such as oxalate, oxalate and oxalate Chemicalbook amide, and the largest output is diethyloxalate, sodium oxalate, and calcium oxalate. Oxalic acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, the cleaning of metals and marbles, and the bleaching of textiles.
Mainly used as reducing agent and bleaching agent, mordant in printing and dyeing industry, also used to extract rare metals, synthesize various oxalates, oxalates and oxamides, etc.
