Melting point: α type: 189.5 ℃ low price oxalic acid, β-type: 182 ℃ Boiling point: boiling point of 150 ℃ (sublimation). Relative density: 1.653 (dihydrate), 1.9 (anhydrous). α type: 1.900, β-type: 1.895 Refractive index: 1.540 Stability: 189.5 ℃ decomposition dissolution: soluble in ethanol. Soluble in water. Slightly soluble in ether. Not soluble in benzene and chloroform. 100ml water soluble dissolved 4900g (25 ° C), the highest concentration of 98%. Other properties: oxalic acid at 100 ℃ start sublimation, sublimation quickly when 125 ℃, 157 ℃ when the supply of a large number of sublimation Fujian oxalic oxalic acid, and begin to decompose. May be reacted with a base, esterification can occur, acid halide, an amidation reaction. Reduction reaction can also occur, thermal decarboxylation reaction. Hygroscopic anhydrous oxalic acid. Oxalic acid can dissolve in water to form complexes with many metals. The main purpose of oxalic acid as a reducing agent and bleach, for the production of antibiotics and other drugs borneol and refining rare metals solvents, dyes reductant, tanning agents. Oxalic acid can be used for cobalt - molybdenum - washing and bleaching of textiles aluminum catalyst production, metal and marble. For metal surface cleaning and treatment, extraction of rare earth elements, textile, leather processing, preparation of catalyst. In organic synthesis industry is mainly used in the production of hydroquinone, pentaerythritol, oxalic acid, cobalt, nickel oxalate, gallic acid and other chemical products. Plastics industry for the production of polyvinyl chloride, amino plastics, urea-formaldehyde plastics, paint and other films. Industrial dye used in the manufacture of base light green and so on. Printing and dyeing industry can replace acetic acid, used as a pigment dye color help agent, bleach. In addition, oxalic acid can be used for the synthesis of various oxalate, oxalate and oxamide and other products, and with diethyl oxalate and sodium oxalate, calcium oxalate, such as maximum yield. Oxalic acid can be used to rust. And the resulting acid oxalate solubility greatly. Oxalic acid can be used as a mordant antimony, iron ammonium oxalate is printed blueprint agents.
