An extensive range of products is available for the mining industry including additives for explosvies, activiated carbon, digestion aids, flocculants, frothers, dispersants, defoamers, calciums chloride and sodium hydrosulphide.

It is created by the reaction of benzyl chloride and sodium hydrosulfide.

Another method entails the alkylation of sodium hydrosulfide.

Sodium hydrosulfide is the chemical compound with the formula NaHS.

A variety of salts are known, including sodium hydrosulfide and potassium hydrosulfide.

Sodium sulfide or sodium hydrosulfide are suitable reducing agents.

It is produced through the reaction between elemental sulfur and sodium hydrosulfide in alcoholic solution:

Sodium hydrosulfide (NaSH)

One of the first reported syntheses of thiobenzophenone involves the reaction of sodium hydrosulfide and benzophenone dichloride:

Reaction of 2-furoyl chloride with sodium hydrosulfide gave 2-furancarbothioic acid, an intermediate to Ceftiofur (Excenel), a third generation cephalosporin antibiotic.

An α-halogenated carbonyl-component reacts with sodium hydrosulfide (NaSH) and forms a Thiol in situ.

Upon combining with alkali metal bases, hydrogen sulfide converts to alkali hydrosulfides such as sodium hydrosulfide and sodium sulfide, which are used in the degradation of biopolymers.

In general, on the typical laboratory scale, the direct reaction of a halogenoalkane with sodium hydrosulfide is inefficient owing to the competing formation of thioethers Instead, alkyl halides are converted to thiols via a S-alkylation of thiourea.

Deuterium nmr provides a unique opportunity to verify that the molecular motion in sodium hydrosulfide, NaSH, in the trigonal phase is the flipping of the SH− ion between two positions parallel and antiparallel to the trigonal axis.

The report contains discussion of various harmful chemicals "likely to be present" in the waste-sodium hydroxide, cobalt phthalocyanine sulfonate, coker naphtha, thiols, sodium alkanethiolate, sodium hydrosulfide, sodium sulfide, dialkyl disulfides, hydrogen sulfide-and notes that some of these "may cause harm at some distance".
