1. Features of Oxalic Acid Anhydrous 98% Purity : oxalic acid Anhydrous is colorless transparent crystals or powder. Its crystal structure has two forms. No smell, sour.
2. Usage of Oxalic Acid Anhydrous 98% Purity : oxalic acid is mainly used to produce drugs such as antibiotics and borneols, as well as solvents, dye reducing agents, leather tannters, etc. of rare metals. In addition, oxalic acid can also be used to synthesize products such as various oxalic acid esters, oxalate, and heroxide, and the output of oxalic acid diettel, sodium oxalate, and calcium oxalate*. Ocpalant acid can also be used in the production of cobalt-molybdenum-aluminum catalysts, cleaning metals and marble, and bleaching of textiles.
oxalic acid is used as experimental reagents, chromatography analysis reagents, dyes intermediates and standard substances.
