The chemistry of sodium hydrosulfide

Do you know the use of sodium hydrosulfide? The application of sodium hydrosulfide and his chemical role is closely related: colorless needle-like crystals easily deliquescent melting point when the liberation of hydrogen sulfide is easily soluble in water and alcohols aqueous solution is strongly alkaline acid reaction to generate hydrogen sulfide industrial general solution is orange or yellow taste bitter.

The use of sodium hydrosulfide: dyestuff industry for the synthesis of organic intermediates and the preparation of sulfur dyes auxiliary tanning industry for hides and leather tanning is also used for wastewater treatment; fertilizer industry for the removal of activated carbon desulfurization agent monomer sulfur manufacture of ammonium sulfide and pesticides, ethanethiol semi-finished raw materials mining industry, a large number of copper ore beneficiation for the production of man-made fibers used in the production of sulfurous acid dyeing and other aspects. Through the above introduction you have a better understanding of sodium hydrosulfide? If you want to know more about sodium hydrosulfide you can refer to: chemical properties of sodium hydrosulfide.

White to colorless, hydrogen sulfide odor, cubic crystals. Industrial products are generally in solution, orange or yellow; Flash point 90 ℃; Melting point 52.54 ℃; Solubility: soluble in water, soluble in ethanol, ether, etc.; Density: relative density (water = 1) 1.79; Stability: stable; Hazardous Labeling 9 (spontaneous combustion items); Main Uses: for the analytical chemistry and the manufacture of inorganic substances 2.

I. Health hazards Invasion route: inhalation, ingestion, percutaneous absorption.

Health hazards: strong irritation to eyes, skin, mucous membranes and respiratory tract. After inhalation, it can cause spasm, inflammation and edema of larynx and bronchial tubes, chemical pneumonia and pulmonary edema. Poisoning and symptoms may include burning sensation, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Direct contact with eyes can cause irreversible damage and even blindness. II. Toxicological information and environmental behavior Acute toxicity: LD5030mg/kg (rat intraperitoneal)

Hazardous Characteristics: Exposure to open flame, high heat or ignition. Oxidizing reaction or even spontaneous combustion occurs when exposed to air.
