Technology Process of β-P4S7

There total 5 articles about β-P4S7 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:

phosphorous + sulfur (7704-34-9) → tetraphosphorus decasulfide (15857-57-5) + P4S4, β (20419-03-8) + P4S8, I (37295-14-0) + P4S7, III (169833-94-7) + tetraphosphorus nonasulfide (25070-46-6)

Guidance literature:

In melt; vac., 10-100 mol% S, heating (1 week, 673 K); extraction (CS2), filtn.; followed by (31)P NMR;

Reference yield:

β-P4S5 (20419-10-7) + triphenyl arsine sulfide (3937-40-4) → phosphorous trisulfide (131105-01-6) + phosphorus sulfide (12037-82-0) + β-P4S7 (169833-94-7)

Guidance literature:

In carbon disulfide; absence of air and moisture; molar ratio P4S5:Ph3AsS=0.9:1, stirring for2 h; product mixt. not sepd., detd by (31)P-NMR spectroscopy;

DOI:10.1021/ic9614881

Reference yield:

sulfur (10544-50-0) + phosphorus (12185-10-3) → phosphorus sulfide (1314-85-8) + phosphorus sulfide (12037-82-0) + γ-P4S6 (189556-96-5) + β-P4S7 (169833-94-7) + α-P4S6 (189556-95-4)

Guidance literature:

In neat (no solvent); Irradiation (UV/VIS); absence of air and moisture; molar ratio P4:S8=8:1, sealed tube, 150 W lamp, 0°C; then heating without irradiation to 80°C for 1 h; further products: β and γ-P4S8, α-P4S9., α-P4S5, β-P4S6, α-P4S8; not isolated, reaction followed by (31)P-NMR spectroscopy;
