This method of preparing nitrogen sulfide was suggested thirty years ago. It was not tried due to the difficulty in obtaining some of the materials, and their toxicity. I am physically unable to try it.

Nitrogen trichloride is reacted with a metal sulfide to produce the metal chloride and nitrogen sulfide. Sodium sulfide was the first thought, but the residual sodium hydroxide from its production would react with the NCl3, very likely violently. A moderator would be needed to slow the reaction to keep from causing catastrophic decomposition of the NCl3.

Carbon tetrachloride and carbon disulfide, both quite toxic and hard to find these days, were suggested, as they are stable with NCl3, and disolve it. Finely powdered iron sulfide was suggested as the metal sulfide. It would have to be added very slowly to prevent a runaway reaction.

The nitrogen sulfide would be filtered from the solvent and dried. Residual iron would be disolved with dilute hydrochloric acid, and the product washed with cold water and dried.

As this has never been tried, to my knowledge, anyone who tries this should NOT try making more than a gram, and take all precautions against the possible violent decomposition of the NCl3. Do not use an organic solvent, as NCl3 reacts violently with many, and forms explosive mixture with most of the rest.

If this works, let us know. We will have a new primary explosive to use.

Last night, someone outside rs.org suggested using hydrogen sulfide instead of a metal sulfide. This may simplify the production, producing hydrogen chloride in addition to nitrogen sulfide.

That would be usefull since HCl isn't soluble in CCl4 and bubles away from mixture with surplus H2S. Could be usefull for controling that reaction since product isn't safest thing on the world you can't be too much cautious.

Nitrogen sulfide has been suggested for use as a primary explosive in detonators, much like lead azide and mercury fulminate. The one thing holding back its use has been an easy and inexpensive way of producing it.

Like all primary explosives, nitrogen sulfide is sensitive. Nitrogen trichloride is the real nasty in this preparation, being both unstable and highly reactive.
