Phosphorus tetritatrisulphide

Table VIII.—Effect of Temperature and Pressure on the Luminescence of Phosphorus Tetritatrisulphide.

G. Lemoine found that phosphorus tetritatrisulphide is rapidly decomposed by a soln. of sodium hydroxide with the evolution of hydrogen mixed with phosphine, and the separation of a small quantity of free phosphorus. The evaporation of the soln in vacuo yields crystals of sodiummonothiohydrophosphite,Na2(HPS02).2or 2f H20. 

Tetraphosphorus Trisulphide or Phosphorus Tetritatrisulphide, P4S3, may be prepared by heating together the theoretical proportions of red phosphorus and sulphur in a sealed tube or in an atmosphere of carbon dioxide.5 It is recommended 6 to use an excess of red phosphorus, mix intimately with powdered sulphur and heat to 100° C. in a wide tube in a current of carbon dioxide. The reaction is...
