Sodium hydrosulfide hydrate may be used in the synthesis of following benzothiazole 4methoxybenzothioamide 2(4methoxyphenyl)imid azoline 7chloro4methoxythio flavone. General description Sodium hydrosulfide hydrate is
Sodium hydrosulfide is a colorless to light yellow crystalline solid or fused mass. It is corrosive to skin and metal. Used in paper pulping, manufacturing dyes,
SODIUM HYDROSULFIDE, SOLUTION is a colorless to lightyellow liquid. Corrosive to metals and tissue. It is used in paper pulping, manufacturing dyes and dehairing hides.
Sodium hydrosulfite is commonly used in the pulp and paper industry for bleaching brightening and decolorization of and recycled fiber. It is also applied extensively to brighten Kaolin clay. In textiles, the primary usage is in processing vat dyes and indigo dyes.
Sodium Hydrosulfite can also be used as a discharging agent to help remove color from fabric, or create neat patterns, or as a step in reverse tiedye. You can adjust it's strength anywhere from 3
Sodium Hydrosulfite, Sodium Dithionite. Sodium hydrosulfite (sodium dithionite, Na 2 S 2 O 4) is an inexpensive and safe reducing agent, which for example enables the reduction of aromatic nitro and diazonium compounds to anilines.
Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the halfneutralization of hydrogen sulfide (H 2 S) with sodium hydroxide. NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution.
TCP Limited is one of the leading manufacturers of Pure Sodium Hydrosulphite (popularly known as Hydros) in India. We adopt a unique process for the manufacture of Sodium Hydrosulphite, known as 'Sodium Formate Process', as against the conventional method of Zinc or Amalgam Process.
Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half neutralization ofhydrogen sulfide with sodium hydroxide. It is a useful reagent for the synthesis of organic and inorganic more..
This Safety Bulletin is published to increase awareness of the hazards associated with NaHS and to outline safety practices to minimize the potential for harm to workers and the public.

5. It is used as reducing agent in chemical industry. 6. Sodium hydrosulfite food additive grade is used in foodstuffs, as bleaching agent and preservative dried fruits, dried vegetable, vermicelli, glucose, sugar, rock sugar, caramel, candy, liquid glucose, bamboo shoots, mushrooms and canned mushrooms.
Industrial chemical like Sodium Hydrosulphite is a watersoluble salt, and can be used as a reducing agent in aqueoussolutions. It is used as such in some industrial dying processes, where an otherwise waterinsoluble dye can be reduced into a watersoluble alkali metal salt.
In contactwith air, mixing sodium hydrosulfite solutions with polysulfide or sulfide containing products may liberate potentially lethal Hydrogen Sulfide gas. Strong acids.
Sodium hydrosulfide, known by its chemical symbol NaHS (often pronounced quot;nashquot;) is used in the leather tanning, pulp and paper, chemical, dye, and mineral extraction industries. NaHS is used as a pure solid (flake) or more commonly as a solution in water.

As a sulfonating agent, sodium hydrosulfite adds sulfur to another chemical compound. As a cation source, sodium hydrosulfite adds a cation, or sodium, to a product system. Sodium hydrosulfite is the common commercial name for products containing sodium dithionite, Na2S2O4, as the active ingredient.
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Sodium hydrosulfide is produced by scrubbing hydrogen sulfide from vent streams with sodium hydroxide. The NaSH solution is filtered and either sold as 44 percent to 46 percent solution, or it is concentrated through evaporation to form flake material of 70 percent to 72 percent NaSH.
