Global Industry Analysis and Forecast 2014 - 2020”.
Sodium sulfide is a water soluble and colorless salt that gives strong alkaline solutions. Sodium
sulfide with its hydrates emits hydrogen sulfide smelling like rotten eggs, when exposed to moist
air. Some of the commonly available grades of sodium sulfide include 60% of Na2S, by weight,
which have a yellow appearance due to presence of polysulfides. These grades are marketed
worldwide as sodium sulfide flakes whose solutions are regarded as colorless despite being
yellow in color. Sodium sulfide is manufactured industrially by the reduction sodium sulfate with
carbon, in the form of coal. The anhydrous salt is prepared in the presence of anhydrous
ammonia by the reduction of sulfur with sodium. Sodium sulfide is also manufactured by other
methods such as reduction of sodium sulfate by reducing agents which are gaseous in nature,
absorption of hydrogen sulfide by sodium hydroxide, and the electrolytic method among others.
Out of these methods, reduction of sodium sulfate has been the most common method to obtain
sodium sulfate. In most of the industrial wastes, sodium sulfate is manufactured in large
quantities. Sodium sulfate as a byproduct is made during the manufacturing of sodium
dichromate, and is considered as a low grade sodium sulfate consequently having a limited
distribution. Owing to this, the sodium sulfate produced is converted to sodium sulfide on
account of its inability of its other uses as it contains highly toxic hexavalent chromium. This
method of obtaining sodium sulfide by the reduction of sodium sulfate...
