Brief Overview
Phosphorus pentasulfide is the inorganic compound with the formula P2S5 or dimer P4S10. This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in carbon disulfide but reacts with many other solvents such as alcohols, DMSO, and DMF. Its tetrahedral molecular structure is similar to that of adamantane and almost identical to the structure of phosphorus pentoxide.
Manufacturing Process
Phosphorus pentasulfide is obtained by the reaction of liquid white phosphorus (P4) with sulfur above 300 °C. The first synthesis of P4S10 by Berzelius in 1843 [5][6] was by this method. Alternatively, P4S10 can be formed by reacting elemental sulfur or pyrite, FeS2, with ferrophosphorus, a crude form of Fe2P (a byproduct of P4 production from phosphate rock):
4 Fe2P + 18 S → P4S10 + 8 FeS
4 Fe2P + 18 FeS2 + heat → P4S10 + 26 FeS
