Sodium Sulphide Flake
Sodium Sulfide & Its Characteristics
Sodium Sulfide, or Na2S, is an inorganic chemical compound with the formula Na2S that has risen to prominence in the organic chemical industry.
It’s a powerful alkaline solution that smells like rotten eggs when exposed to moist air. The solution of Sodium Sulphide obtained from the process is concentrated to 10-12% and is available at different percentages in tanker loads.
Despite the fact that the solid-state is yellow, the solution is colorless. In Industries Na2S is produced by carbothermic reduction of sodium sulfate often using coal. It’s usually labeled as “sodium sulphide flakes” in the grades.
When Na2S and its hydrates are exposed to damp air, hydrogen sulphide is produced. This discharge has a rotten egg odour.
Sodium sulphide in solution has a yellow solid form and is sold in grades known as sodium sulphide flakes. Disodium sulphide is the IUPAC designation for sodium sulphide.
Applications of Sodium Sulphide
Sodium sulfide is a versatile chemical used across multiple industries. It is essential in leather processing, rubber chemical production, sulfur dyes, oil recovery, and the pulp and paper industry. This compound, Na₂S, releases hydrogen sulfide when exposed to moist air, giving off a rotten egg smell. Sodium sulfide also has anti-inflammatory and protective properties in biological applications. Produced via carbothermic reduction of sodium sulfate, it is available in concentrated forms and plays a crucial role in industries such as mining, metallurgy, textiles, and water treatment.
Chemical Reactions of Sodium Sulphide
Sodium Sulphide Flake
This chemical compound is very alkaline and incompatible with some acids. Generally, these compounds are used as reducing reagents. Also, this compound is not compatible with oxidizing compounds and reacts strongly.
Sodium sulfur and some other sulfides are not compatible with acids and show strong reactions and emit a gas called hydrogen sulfide. This gas is very dangerous and poisonous and is flammable. The mineral salt of this material is also flammable. If you put this material under high heat, it will decompose and eventually catch fire. The important thing is that if this material is stored in a dry environment without moisture, the intensity of the fire will increase.
The remarkable thing about this chemical compound is that it should not be exposed to heat and high temperature, otherwise it will turn into sodium oxide and sulfur oxide foam, both of which are highly toxic and harmful to the environment. They hurt. Sodium sulfur reacts strongly with carbon, diazonium salts, activated carbon and some other oxidizing substances, and people who use these substances in the production of their products must be very careful and provide safety measures for their employees.
Uses of Sodium Sulphide
Pulp and paper: Sodium sulphide flakes is primarily used in pulp and paper industry in the Kraft process.
Leather: They use Sodium sulfide flakes as a sharpening agent in soaking and hair removing processes in the leather industry in tanneries.
Textile: sodium sulphide flakes is also used as a bleaching, desulphurizing and dechlorinating agent in textile industry.
Chemicals: sodium sulfide flakes is used in chemical manufacturing as a sulfonation and sulfomethylation agent. It is also used in the production of rubber chemicals, sulfur dyes and other chemical compounds.
Dyeing: sodium sulphide flake is also used in dying industry for improving the effectiveness of coloring and saving dyes.
Potential Health Effects
Sodium sulfide is a strong base and can cause severe burns on the mucous membrane. Hydrolysis by gastric fluids releases toxic hydrogen sulfide. The symptoms and effects are similar to those under inhalation, above.
Ingestion: Corrosive, toxic.
Skin Contact: Irritant. Contact with skin can produce serious caustic burns with painful inflammation and possible destruction of tissue.
Eye Contact: Irritant. Inflammation, tearing and pain may be expected. Severe contact can cause destruction of tissue.
Handling and Storage
Store in a tightly closed container. Protect from light. Protect container from physical damage. Store in an explosion-proof refrigerator. Isolate from acids and alkalis.
Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
