Aminopolycarboxylate chelating agents are used extensively in many domestic products and industrial processes, with the most important applications in cleaning compounds, pulp and paper manufacturing, and agriculture.
As the process for industrial production of aminocarboxylic acid salts, there is currently used generally the Strecket Process in which a glycine salt, an imiodiaacetic acid salt , a nitrilotriacetic acid salt or the like is obtained using hydrocyanic acid and formaldehyde as raw materials.
The market is witnessing emergence of many new chelating products and the transition of existing products towards newer markets and applications. Nuclear sector is one such prospective market, where chelating agents are employed to clean up nuclear waste at government sites or at nuclear power plants.
Chelating agent usage spans a large number of diverse end-use markets. Important applications include pulp and paper processing; industrial water treatment; household, institutional and industrial cleaning compounds; metal finishing; agriculture; photography; rubber processing; use in food, pharmaceuticals, cosmetics and toiletries; and textile treatment.
