WHAT IS SODIUM SULFIDE?

Sodium sulfide is a chemical compound with the formula Na2S and its hydrated form with the formula Na2S.9H2O, both of which are water-soluble salts and produce strong and colorless alkaline solutions. Although sodium sulfide is a yellow solid, its solution is colorless. Sodium sulfide is produced in crystallized, cracked and broken forms and releases hydrogen sulfide gas when exposed to air, which smells like rotten eggs. Sodium sulfur reacts with hydrogen peroxide to produce sodium sulfate.

APPLICATION OF SODIUM SULFIDE

It is mainly used in textile, artificial silk and leather industries. Also in the paper industry, photography (coloring of black and white photos), oil recovery, paint and detergent manufacturing, rubber production, sulfur textile dyes, parasiticides, organic compounds preparation and water purification (as a metal precipitator) is used. Sodium sulfide with low iron content is preferred in applications where high purity is crucial and the presence of iron could negatively impact the process or final product quality.

PRODUCTION OF SODIUM SULFIDE

In industry, sodium sulfide is obtained from the reduction of sodium sulfate with coal. These raw materials are found in abundance in nature. This reaction is carried out inside a furnace at a temperature of 1000 degrees Celsius. 0.5% of sodium carbonate is added to this reaction. This substance acts as both a catalyst and a neutralizing agent for any free acid. The product obtained from the furnace is known as black ash, which is cooled and crushed and washed several times by hot water. To prepare white crystals of sodium sulfide, 0.5% of sodium cyanide is added to the liquid before crystallization.

In the laboratory, it is prepared from the reaction of sulfur with sodium in anhydrous ammonia solution or with sodium in dry tetrahydrofuran with the catalyst of naphthalene. It is also obtained from the reaction of hydrogen sulfide and sodium hydroxide. In this method, sodium sulfide is produced in the form of flakes.
