Physical properties 

Sodium gluconate forms colorless crystals.

Soluble in water and ethanol .

Application 

In industrial detergents 

Sodium gluconate and gluconic acid are used as complexing agents for bivalent or trivalent metal cations (Ca 2+ , Mg 2+ , Fe 3+ , Al 3+ ) in industrial alkaline cleaning solutions. They are particularly effective in this application, even when compared to agents such as NTA and EDTA . Gluconic acid and sodium gluconate are commonly used in liquid formulations in combination with other ingredients such as surfactants , sodium hydroxide, sodium silicate, and phosphates. Such formulations can be more effective due to synergy, arising from a combination of the properties of two or three components: Trisodium phosphate, used as a detergent , does not have complexing properties and in hard water can cause precipitation of calcium in the form of an insoluble phosphate salt. Sodium gluconate added to the solution reacts with calcium ions to form a soluble chelate compound. Surfactantsgenerally more effective in soft or demineralized water. Since it is very expensive to demineralize water, adding sodium gluconate to the formulation is an economical solution. Silicates complement the action of sodium hydroxide by imparting increased alkalinity and preventing corrosion. Sodium gluconate imparts synergy to these properties. Due to the combination of complexing, dispersing and anti-corrosive properties, high solubility and increased stability in a strongly alkaline environment, sodium gluconate is the best complexing agent for creating alkaline formulations.

Additive to concrete and building mixtures 

Sodium gluconate slows down the setting of concrete , lowers water content and improves plasticity even at low dosages. Its use contributes to obtaining concrete with increased strength after 28 days. The principle of action of sodium gluconate is based on several interrelated mechanisms: - Adsorption: Sodium gluconate is adsorbed on the surface of cement particles during hydration and prevents their contact with water, slowing down the setting. - Sedimentation (precipitation): in the aqueous phase, sodium gluconate interacts with calcium ions, forming an insoluble and impermeable layer of calcium gluconate on the surface of the cement particles. This slows down hydration and lengthens the hardening time. The mechanical strength of the cement is increased under conditions favorable for the formation of long microcrystalline fibers. - Complexation: sodium gluconate isolates calcium ions, preventing the formation of crystal nuclei. - Dispersion: Sodium gluconate helps to disperse the cement particles in the mixture, reducing the effect of Van der Waals forces and improving wetting. This increases the fluidity or allows the water content to be reduced. It is known that with a low water content, microcrystalline fibers of increased length are not required to bind all cement particles. This leads to an increase in the strength of the cement after 28 days. Thus, sodium gluconate increases plasticity and strength by reducing the water content of the mixture, and also slows down the hardening.

Cement additive for the oil industry 

Sodium Gluconate is used in the oil industry to cement boreholes. Cementing serves for:

fixing the drill string relative to the sides of the well

drill string enclosures

protecting the drilling space from pressure fluctuations and corrosion

reduction of fluid loss through the permeable layer

According to American Petroleum Institute standards, there are several grades of cement that are used for this process. Some types of cements contain retardants, in these types of cements sodium gluconate can be injected directly into the cement. Another related application of sodium gluconate is in the treatment of a production well. Operating time, recoil can be reduced due to the formation of salts such as calcium sulfate or calcium carbonate, which reduce the geological permeability of gas and oil. In these cases, it is possible to use acid or alkali to destroy these formations. The addition of sodium gluconate to the working fluid can improve properties by keeping the salts dissolved. Related Uses: Preventing crystal growth. Sodium gluconate prevents the formation of salt and mineral deposits. Sodium gluconate is absorbed on the surface of the crystal and prevents its further growth. Thus, the size and number of crystals changes. Corrosion inhibitor. In an alkaline environment, especially in enriched borax, sodium gluconate is a good corrosion inhibitor for ferrous metals such as cast iron or steel.

Metallurgical applications 

In steel production and especially in aluminum production - sodium gluconate works as a well-known, fairly effective chelating agent that binds metal ions and thereby prevents the deposition of aluminum hydroxide on surfaces, allows the sediment to be easily removed during filtration. When pickling steel, sodium gluconate prevents metal salt deposits from settling in the bath or on the sheets, thereby improving the condition of the metal surface. Etching of metals has as its goal either the continuous dissolution of a thin layer from the metal surface - matt etching, or etching on the surface of only individual places - etching of drawings, letters. In the latter case, the metal surface is covered with a protective layer, on which a pattern is applied, cut with a sharp tool (needle) to the metal, so that
