SODIUM Gluconate

Sodium Gluconate is the sodium salt of gluconic acid with chelating property. Sodium gluconate chelates and forms stable complexes with various ions, preventing them from engaging in chemical reactions.
Sodium gluconate is an organic sodium salt having D-gluconate as the counterion. It has a role as a chelator. It contains a D-gluconate.


Sodium gluconate is a compound with formula NaC6H11O7. It is the sodium salt of gluconic acid. 
Its E number is E576. Sodium gluconate is widely used in textile dyeing, printing and metal surface water treatment. 
It is also used as a chelating agent, a steel surface cleaning agent, a cleaning agent for glass bottles, and as a chelating agent for cement, plating and alumina dyeing industries. 
It is a white powder that is very soluble in water.

IUPAC name: Sodium (2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanoate
Other names: Sodium D-gluconate

CAS Number: 527-07-1 

Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. 
It is a white to tan, granular to fine, crystalline powder, very soluble in water. 
Non corrosive, non-toxic and readily biodegradable (98 % after 2 days), sodium gluconate is more and more appreciated as chelating agent.

The outstanding property of sodium gluconate is its excellent chelating power, especially in alkaline and concentrated alkaline solutions.
It forms stable chelates with calcium, iron, copper, aluminium and other heavy metals, and in this respect, it surpasses all other chelating agents, such as EDTA, NTA and related compounds.

Aqueous solutions of sodium gluconate are resistant to oxidation and reduction, even at high temperatures. However, it is easily degraded biologically (98 % after 2 days), and thus presents no wastewater problem.

Sodium gluconate is also a highly efficient set retarder and a good plasticiser / water reducer for concrete, mortar and gypsum.

Product Definition
Sodium Gluconate is the sodium salt of gluconic acid especially designed for high rate water reducing admixtures.

Use

Sodium Gluconate is used in the following conditions and applications.

• In high rate water reducing admixture formulations requiring good workability and slump retention.
• In admixture formulations designed for tight reinforced structural elements such as columns, shear wall and beams.
• In admixture formulations designed for Industrial floor.
• It allows economicaly design of polycarboxylate admixtures.

Advantages and Properties

• Owing to its organic and inorganic compounds, Sodium Gluconate is highly compatible with polycarboxylate based admixtures, besides high dosages allows more economical admixture cost.

• Sodium Gluconate increase the setting time of the concrete

• In the admixture recipes the use of Sodium Gluconate in an appropriate dosage provides a greater ease of workability, makes the concrete easier to mix, transport, place in the formwork and compact concrete.

• Sodium Gluconate preserves the consistency of concrete for longer than reference blank concrete.

• Sodium Gluconate improves strength and durability by achieving the targeted consistency class with a lower water / binder ratio.
