Abstract: Alkali thiocyanates are prepared by reacting alkali cyanides with sulfur in the presence of alkali sulfide in a molar amount of 1:1000 to 1:2000 as a solubilizer for the sulfur. The reaction is carried out above the melting point of sulfur, preferably in an alkali thiocyanate solution. The alkali sulfide is then converted to the sulfate by oxidation with hydrogen peroxide.
