OTHER USED

♦ In the photographic industry to protect developer solutions from oxidation.
♦ It is used in the production of rubber chemicals and other chemical compounds.
♦ It is use in other applications include ore flotation, oil recovery, food preservative, making dyes, and detergent.

* Properties: colorless orthogonal crystal. Deliquescent. It is unstable and melts into black liquid at about 350 ℃. Soluble in water or alcohol. Aqueous solution has a strong alkaline reaction and releases H 2 S violently when encountering acid. Industrially produced sodium hydride is generally an orange or yellow solution with a bitter taste. Corrosive to human skin.

* Uses: used as raw material for semi-finished products of ammonium sulfide, sodium methanethiol and ethyl mercaptan. It is widely used in copper ore dressing in mining industry. Dehairing and tanning of raw skins in the leather industry. Used in chemical industry to remove the monomer sulfur in activated carbon desulfurizer. In the production of artificial fiber for sulphuric acid dyeing.

* Packing: Solid: plastic woven bag of 25 kg. Liquid: bulk, tank truck.

Chemical properties:

1, stable under normal temperature and pressure

Soluble in water and alcohol. Aqueous solution is strongly basic. When acid breaks down, hydrogen sulfide is formed. Industrial products are generally solution, orange or yellow, bitter taste. Deliquescent, hygroscopic, soluble in water and ethanol. When heated in dry air, it turns yellow and orange, and appears black when melting. It is dissolved in HCl and produces H2S, and the reaction is intense. Easy deliquescence, hygroscopic, easy oxidation, preservation often release hydrogen sulfide and sulfur.

2. It is easy to hydrolyze in humid air and produce sodium hydroxide and hydrogen sulfide

Storage method:

Room temperature sealed away from light, ventilated and dry
