Oxalic acid, namely acetic acid, one of the simplest organic dicarboxylic acid. Simple structure HOOCCOOH. It is generally colorless crystals harmful oxalic acid manufacturer in Dongguan, will make the body's pH is out of balance, affect the development of children, oxalic acid plays an important role in the industry, oxalic acid can rust. Oxalic acid found in nature, often in the form of oxalate in plants such as barberry, sheep hoof grass, wood sorrel and sorrel acid membrane manufacturers, almost all plants contain oxalates. Sodium France after the purification of carbon monoxide under pressure in the case of oxalic acid and sodium hydroxide manufacturer to produce sodium oxalate manufacturer in Shenzhen, and then generate high temperature dehydrogenation of sodium oxalate, sodium oxalate and then the lead of (or calcification), acidification, crystallization and dehydration and other processes, to be finished oxalic acid. Carbon monoxide and sodium hydroxide synthesis pressure is generally 1.8-2.0MPa. Dehydrogenation temperature is 400 ℃. Oxidation of starch or glucose solution as a raw material, alumina catalyst in the presence of nitric acid - sulfuric acid oxidation reaction in oxalic acid. Emissions of nitrogen oxide absorber recovery sent dilute nitric acid.
