APPLICATIONS |
||
| Gluconic acid is a polyhydroxycarboxylic acid with six carbon length. It is derived from glucose by oxidation of the aldehyde group on the C-1 to a carboxyl group. It is abundant in plants, fruits and other foodstuffs. Commercially the physiological d-form gluconic acid is prepared by fermentation process. It has a carboxylic group and five hydroxy groups, and thus is a good chelator particularly in alkaline conditions. Chelation is a chemical combination with a metal in complexes in which the metal is part of a ring. Organic ligand is called chelator or chelating agent, the chelate is a metal complex. The larger number of ring closures to a metal atom is the more stable the compound. Chelation is applied in metal complex chemistry, organic and inorganic chemistry, biochemistry, and environment protection. It is used in chemotherapeutic treatments for metal poisoning. Chelating agents offers a wide range of sequestrants to control metal ions in aqueous systems. By forming stable water soluble complexes with multivalent metal ions, chelating agents prevent undesired interaction by blocking normal reactivity of metal ions. Heavy metals are chelated in alkaline solution and their interferences are eliminated gluconic acid. Concentrated gluconic acid solution contains certain lactone structure, a neutral cyclic ester, showing antiseptic property. Gluconic acid and its derivatives (salts or esters) are used in the formulation of pharmaceuticals, foods, and cosmetics as mineral supplements to prevent the deficiency and as buffer salts. They are used as ingredients in various hygienic products. In industrial applications, they are used for scale removal in metal cleanings, industrial and household cleaning compounds including mouth washer, metal finishing, water treatments, and as paper and textile auxiliaries. | ||
