Technology Process of tetraphosphorus pentasulphide

There total 12 articles about tetraphosphorus pentasulphide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

sulfur (10544-50-0) + phosphorus sulfide (1314-85-8) + phosphorus (12185-10-3) → tetraphosphorus nonasulfide (25070-46-6) + tetraphosphorus pentasulphide (15578-54-8) + γ-P4S8 (190910-11-3)

Guidance literature:

In neat (no solvent); absence of air and moisture; molar ratio P4:S8=8:1, sealed tube (12 Torr), heating to 80°C; not isolated, reaction followed by (31)P-NMR spectroscopy;

DOI:10.1021/ic9614879

Reference yield:

phosphorus sulfide (1314-85-8) + sulfur (7704-34-9) → phosphorus sulfide (12037-82-0) + tetraphosphorus pentasulphide (15578-54-8)

Guidance literature:

In carbon disulfide; dissolving P4S3 and S in CS2 and heating up to 170-200°C under pressure;; mechanical separation; recrystn;;

Reference yield:

sulfur (10544-50-0) + phosphorus (12185-10-3) → phosphorus sulfide (12037-82-0) + tetraphosphorus pentasulphide (15578-54-8) + γ-P4S5 (256637-13-5) + phosphorus sulfide (39350-99-7) + β-P4S4 (20419-03-8)

Guidance literature:

In neat (no solvent); absence of air and moisture; molar ratio P4:S8=8:1, sealed tube (12 Torr), succesive heating (°C/d) to 80/55, 100/7, 120/4. 150/3; further products: β-P4S6, α-P4S8; 8 other phosphorus sulfides as intermediates; not isolated, reaction followed by (31)P-NMR spectroscopy; Kinetics;
