Sodium gluconate

Sodium Gluconate is the sodium salt of gluconic acid, and is produced by fermentation of glucose. It is a white powder that is very soluble in water. 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.

Production

Sodium gluconate is produced by the fermentation of glucose, typically from corn or rice. The glucose is fermented by a bacterium, which produces gluconic acid. The gluconic acid is then neutralized with sodium hydroxide to produce sodium gluconate.

Uses

Sodium gluconate has a wide range of uses in various industries.

Textile Industry

In the textile industry, sodium gluconate is used as a chelating agent. It helps to remove metal ions from fabrics, which can interfere with the dyeing process.

Water Treatment

Sodium gluconate is used in water treatment processes. It acts as a chelating agent, binding to heavy metals and other contaminants, which can then be removed from the water.

Cleaning Agent

Sodium gluconate is used as a cleaning agent for glass bottles and steel surfaces. It is particularly effective at removing rust and other forms of oxidation.

Construction Industry

In the construction industry, sodium gluconate is used as a chelating agent in cement. It helps to slow the setting time of the cement, allowing for more precise application.

Health and Safety

Sodium gluconate is generally considered safe for use. However, it can cause irritation if it comes into contact with the skin or eyes, and can be harmful if swallowed in large amounts.
