METHOD OF OBTAINING ANHYDROUS SODIUM SULPHIDE

In the production of anhydrous sodium sulfide, sodium sulfide containing 35-45% water with mixing is passed through an apparatus, in which the product temperature of approximately 20 degrees C at the place of solid injection gradually rises to at least 180 degrees C while the subpressure is maintain...
