oxalic acid Usage
Oxalic acid is mainly used in the production of antibiotics and borneol and other drugs, as well as the extraction of rare metals solvent, dye reducing agent, tanning agent. In addition, oxalic acid can also be used in the synthesis of various oxalates, oxalates and grass Chemicalbook amide and other products, and oxalate diethyl oxalate and sodium oxalate, calcium oxalate and other production of the largest. 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
