Synthesis of nitrogen tetrasulfide

Preparation of nitrogen tetrasulfide

Preparation of nitrogen tetrasulfide

Preparation of nitrogen tetrasulfide

5 ml of sulfur monochloride was diluted to about 150 ml with ether and a stream of dry ammonia was passed through. The yield is greatest when the gas is passed through at the rate of 900-1000 ml per minute. The mixture turns brown at first, but after about half an hour becomes orange. On standing, an orange precipitate separates out, leaving a bright red solution. The precipitate is extracted with ether and the solution is allowed to evaporate in the air, leaving orange-yellow crystals having a very strong, characteristic odor. When the solution is evaporated by heating, most of the crystals decompose into sulfur, nitrogen and perhaps some other sulfide of nitrogen. In order to avoid the loss of ether while the reaction between the sulfur monochloride and ammonia is taking place, the flask should be immersed in an ice-bath and fitted with a reflux condenser.
