Chemical Properties Of Sodium Gluconate

Sodium gluconate, also known as Sodium D-gluconate, MF: C₆H₁₁O₇Na, MW: 218.14, is a white or pale yellow crystalline powder. It is a sodium salt of carboxylic acid produced by the oxidation (or biological fermentation) of glucose. As a non-toxic, readily biodegradable organic acid salt, it possesses chelating properties, forming stable soluble complexes with metal ions such as Ca²⁺, Mg²⁺, and Fe³⁺, along with corrosion inhibition and water solubility.

Product Application Of Sodium Gluconate

  1.  Sodium gluconate is primarily used as a concrete retarder to extend initial setting time, facilitating long-distance transport and large-volume pouring.
  2.  In the food industry, sodium gluconate serves as a chelating agent to prevent oxidation discoloration and flavor deterioration caused by metal ions in food; as a preservative; and as a flavoring agent.
  3.  Sodium D-gluconate also serves as an electrolyte supplement and antidote (adjuvant treatment for heavy metal poisoning) in pharmaceutical applications.
  4.  In water treatment, it functions as a scale inhibitor and corrosion retardant to protect metallic equipment.
  5.  Additionally, it is employed as a complexing agent in electroplating and as a detergent/cleaning agent.
