Information @ a Glance

Contents on the CD Rom

  • Sodium sulfide is the name used to refer to the chemical compound Na2S but more commonly its hydrate Na2S.9H2O. Both are a colorless water-soluble salts that give strongly alkaline solutions.
  • Sodium Sulfide is a yellow to red solid, readily soluble in water, slightly soluble in alcohol. It is a strong reducing agent and reacts with oxidants.
  • Industrially Na2S is produced by reduction of Na2SO4 with carbon, in the form of coal
  • In the Kraft process the fibres are liberated in the cooking plant by dissolving the lignin and part of the hemicellulose in the cooking chemical solution (white liquor), which contains sodium hydroxide and sodium sulphide as active chemicals.
  • Carbonation conversion of aqueous sodium sulfide, i.e., with CO2 gas, is particularly favorable since COa is readily available in the flue gas of carbothermic reduction furnaces.
  • The enzymatic treatment of hides and skins can be considered as a cleaner technology only if the amount of sodium sulphide is reduced substantially. However it is not yet possible to use less than 1% of sodium sulphide for bovine hides.
  • Sodium Sulfide Pre-treatment Increases the Rate and Sensitivity of Silver Precipitation onto 3,3-diaminobenzidine(DAB). While looking for ways to maximize the sensitivity of the silver enhancement, we observed that pre-treatment of the DAB with sodium sulfide was very effective for this purpose
  • Sodium Sulfide is used to determine the phosphate in sugar cane juice and sodium sulphide is found to be a very effective reducing agent but not commonly used for phosphate determination.
  • Sodium Sulfide is used in water treatment as an oxygen scavenger agent, in the photographic industry to protect developer solutions from oxidation, in textile industry as a bleaching, as a desulfurizing and as a dechlorinating agent and in leather trade for the sulfitization of tanning extracts.
  • Sodium Sulfide is used in the production of rubber chemicals, sulfur dyes and other chemical compounds.
  • The main cost increase in chemicals was due to the use of glucose which is 17% more expensive than sodium sulphide
  • During our religious holiday of sacrifice, a leakage was detected on the retaining wall of sodium sulphide pool towards the dry irrigation water channel, which is located along the border of the plant.
  • The oral ingestion of alkali sulphides has been reported to cause nausea, vomiting and epigastric pain, as well as irritate the mucous membranes; it has been estimated that an oral dose of 10 to 15 g sodium sulphide would be fatal to humans.
  • The first factory is in DaLian, produce solid sodium sulphides in low production. The contain of it's production is Na2S 42%. Up to early of 40's. A Chemical Factory started to produce solid sodium sulphides, the contain of Na2S is up to 52%.
