Descripción del producto

Oxalic acid Property: Other name: ethanedioic acid, carboxylic acid structural formula:HOOCCOOH molecular weight:**6.*7. Oxalic acid generally contains double molecular crystal water, transparent crystal or white powder, no smell, acid. There are 2 types of crystal stucture:a(rhombic) and b( ). Melting point and relative density:a***9.5℃, 1.**0, b***2℃, 1.**5. oxalic acid will lose crystal water in dry air or heating up. It’s sublimated easily with the temperature of **0℃, rapidly with **5℃ and **7℃ in large quantity and began to disassemble. It’s easily dessolved in hot water & ethanol, slightly dissolved in cold water, tinily dessolved in aether, not dissolved in benzene &chioroform. Oxalic acid is akind of strong acid in organic acid, being neutralized with alkali. Application:getting rid of rust, bleaching, printing and dyeing, construction cleaning, producing the activator of cobalt, molybdenum and aluminium, cleaning metal and marble and whitening textile. oxalic acid is a kind of bactericide which can be used as feedingstuff sterilization and animals could eat directly. 　　 Quality index： index superior Oxalic acid content ≥ *9.6% Vitriod acid radical(SO**-) ≤ 0.*8% Heavy metal（Pb） ≤ 0.**1% Fe（以Fe3+计） ≤ 0.***5% chloride（Cl-） ≤ 0.**3% residue（**0℃） ≤ 0.*8%
