Useful:

• Chemical Classes: Other Classes -> Sulfur Compounds
• Canonical SMILES: [Na+].[SH-]
• Recent EU Clinical Trials: A randomized, double-blind, placebo-controlled, multi-center study of IK-1001 to evaluate safety, population pharmacokinetics and proof-of-concept efficacy for reduction of ischemia-reperfusion mediated cardiac injury in subjects undergoing coronary artery bypass graft (CABG) surgery.
• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Inhalation may cause lung oedema. Corrosive on ingestion. The substance hydrolyses rapidly on exposure to moisture releasing H2S. See ICSC 0165 .
• Uses: the copper ore beneficiation,the sulfurous acid dyeing of manmade fibre,the synthesis of organic intermediates,the preparation of auxiliary agent of sulfur dyes,and waste water treatment; raw material to produce ammonium sulphate and ethanethiol In paper pulping, in dyestuffs processing, in rayon and cellophane desulfurizing, in unhairing hides and as a bleaching reagent Sodium hydrogen sulfide is used in cloth, paper, pulp and dyestuff industries. It acts as a floating agent in copper mining as well as to remove hairs from hides in leather industries. It is also used as an intermediate in synthetic chemistry. It is utilized as a raw material in the production of ammonium sulphate and ethanethiol.

Technology Process of Sodium hydrosulfide

There total 1 articles about Sodium hydrosulfide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

hydrogen sulfide (7783-06-4) + sodium (7440-23-5) → NaHS, low temperature (16721-80-5)

Guidance literature:

In neat (no solvent); in a glove box; react. of metal with liq. S-compd. at 340-420 K in an autoclave; loading polycrystalline samples in glass capillaries under dry Ar (preventing decompn. by moisture), annealing of glass capillaries at 420 K for several weeks, slowly cooling down to room temp. (improving crystallinity);
