Sell Oxalic Acid

Description

Oxalic acid, also known as oxalic acid, is the most simple binary acids. Crystal heated to **0 , loss of crystal water and become anhydrous oxalic acid. Anhydrous oxalic acid melting point of **9.5 , can dissolve in water or ethanol, insoluble in ether. Laboratory thermal decomposition of oxalic acid can be used to control the take of carbon monoxide gas. In human urine also contains a small amount of oxalic acid, calcium oxalate is the main component of urinary stones. The most simple binary acids. Formula HOOCCOOH. Widespread in nature, especially plants, such as herbs, rhubarb is a plant, shamrock, spinach, etc., and often the form of potassium salt. Meat in the human or animal urine, with calcium oxalate or uric acid in the form of grass. In addition, the kidney and bladder stones also contain calcium oxalate. Anhydrous oxalic acid is a colorless crystal, there is hygroscopic; melting point **9.5 ; when the sublimation at about **7 ; soluble in water, can dissolve in ether. Goods oxalate crystals containing two molecules of water; colorless crystals; melting point **1.5 , heated to **0 to lose crystal water; slightly soluble in ether. Carboxylic acid molecule directly linked to two, with some special properties, such as oxalic acid with the reduction, enabling reduced to divalent manganese potassium permanganate, the reaction was used in the determination of quantitative analysis of the concentration of potassium permanganate method; Oxalic acid is also used for fiber, oil and leather industries, bleaching agent, but also reducing the use of it. Oxalic acid decarboxylation heat dehydration occurs to produce carbon dioxide, carbon monoxide and water. Oxalic acid with many metals to form water-soluble complexes.
