Sodium gluconate is the sodium salt of gluconic acid obtained from the fermentation of glucose. This salt is one of the most useful chemical compounds that is used in various industrial and laboratory grades. The main advantage of sodium gluconate is its excellent chelating power, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminum, and other heavy metals. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.
Physical and Chemical Properties:
Sodium gluconate is a white, noncorrosive, nontoxic, biodegradable powder, soluble in water and partially soluble in ethanol and methanol, which is resistant to oxidants and reducers even at high temperatures; The following table lists some of the important chemical and physical properties of this compound:
|PH||Between 6,5 and 7,5|
|Density (g/cm3 at 25 °C)||1.8|
|Melting point (° C)||170-175|
|Solubility||Very soluble in water. Sparingly soluble in ethanol|
Formula and Structure of Sodium Gluconate:
The chemical composition of sodium gluconate with the chemical formula C6H11O7Na consists of a six-carbon chain with five hydroxyl groups ending in a carboxylic acid group. The proximity of oxygen atoms in the chemical structure contributes to its function as a highly efficient chelating agent.
The Production Method of Sodium Gluconate:
This product is produced in industrial grade and its other grades on large commercial scales using a fermentation process. In this method, first glucose is converted to gluconic acid and then gluconic acid is converted to sodium gluconate. The fermentation method produces effluent that can be dangerous to the environment, so in recent years, catalytic methods have received more attention due to their lower risks to the environment.

Sodium Gluconate Uses:
Sodium gluconate is widely used in dyeing, printing, water treatment, food industry, medicine, cosmetics, household detergents, plating, chemical fertilizers, photography, textiles, plastics, polymers, paper, cement, and protection Metals such as stainless steel are used; In the following, we will explain some of its important and main uses:
This substance is used in the food industry due to its stabilizing, separating, and thickening properties. Among the products that use this combination, we can mention dairy products, processed fruits, vegetables, spices, cereals, processed meats, packaged fish, etc. like Sodium nitrite
In most detergent formulations, this substance is used as a chelating agent and corrosion inhibitor. One of the important properties that sodium gluconate gives to the detergent is that it prevents the re-deposition of ions and soil molecules on the surface.
Due to the reactions that this compound shows with metal ions, it is used in the plating industry. The chelating properties of this compound increase the efficiency of plating baths. Gluconate can be used to create clarity and shine in copper, zinc, and cadmium plating baths.
This material is used in concrete mixes. Using this combination can have many benefits such as improving efficiency, reducing setting time, reducing water, resistance to frost, cracking, drying, and shrinkage.
sodium gluconate is used in medicine to treat patients with anemia. It is also used to treat chronic kidney disease, which usually affects patients on dialysis. As with most medicines, talk to your doctor about the benefits and possible side effects before taking sodium gluconate. Other applications of this material include cleaning machines, equipment, and shelves in the food industry, cleaning agents for ceramic surfaces, and balancing anion cation in electrolytic solutions.
