description A method of preparing anhydrous sodium sulfide having an Na2S content of at least 98 wt %, by drying hydrous sodium sulfide having a water content of 35 to 45%, provided as a solid or in liquefied form, by intensively kneading and mixing hydrated sodium sulfide at an elevated temperature and pressure to thereby liquify said hydrated sodium sulfide and obtain the anhydrous sodium sulfide.
