EINECS 235-225-5 The employment of ammonium sulfide for a convenient cyclization of α-cyano-α-(dichloromethyleneimino)alkanoic acids, available from the corresponding isocyanides and chlorine, into 5,5-disubstituted 2,4-dithiohydantoins has been described a few years ago (Scheme 39) <1998S1437>. The reaction is proposed to occur by addition of sulfide and cyclization to a thiazole ring followed by ring opening and new closure.

Ammonium sulfide

It was therefore suggested, and later substantiated by Westfall (1945) , that the cause of acute mortality was suffocation due to the inability to clear a Pb-induced coagulation of mucus at the gill. AMMONIUM SULFIDE SOLUTION is a strongly alkaline aqueous solution. Reacts with acids to generate toxic gaseous hydrogen sulfide. Reacts with bases to release gaseous ammonia. May react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides.

These chemicals have a very strong and unpleasant Ammonium sulfite is used as a preservative for fixers in photography. When film photographs are being developed ammonium sulfite can be one of the reducing agents used to preserve the hypo (Sodium or Ammonium Thiosulfate).

Ammonium sulfide solutions are used occasionally in photographic developing, to apply patina to bronze, and in textile manufacturing. Also, due to its offensive smell, it is the active ingredient in a variety of pranks including the common stink bomb . 2021-03-01 · Ammonium sulfide is an unstable ammonium salt with the formula (NH 4) 2 S. It is a yellowish solid, stable below -18 °C. As the hydrosulfide ion cannot be deprotonated to an appreciable amount by ammonia (pKa = 15), ammonium sulfide solutions also contain free ammonia and ammonium hydrosulfide (NH 4)SH. Sigma-Aldrich offers a number of Ammonium sulfide solution products.
