Definitions

  • the yield can generally be still further increased by adding to the reaction mixture a small amount of sulfur before the addition of the alkali metal.
  • the quantity ofsulfur may vary within wide limits. The addition of 1 part of sulfur for every 10 parts of alkali metal sufiices to produce a positive effect, preferably there is used 1 part of sulfur for every 3 parts of alkali metal, and in any case not more than. 1 part of sulfur for every 1 part of alkali metal.
  • the sulfur may be replaced by an equivalent amount. of anhydrous sodium sulfide or by introducing an equivalent amount of hydrogen sulfide.
