Technology Process of tetraphosphorus heptasulfide

There total 5 articles about tetraphosphorus heptasulfide 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:

P2SI4 → diphosphorus tetraiodide (13455-00-0) + tetraphosphorus heptasulfide (263358-58-3) + phosphorous triiodide (13455-01-1)

Guidance literature:

In neat (no solvent); decompn. on heating;;

DOI:10.1007/BF00623583

Reference yield:

tetraphosphorus decasulfide (15857-57-5) → tetraphosphorus nonasulfide (25070-46-6) + tetraphosphorus heptasulfide (263358-58-3)

Guidance literature:

In further solvent(s); byproducts: sulfur, undefined P sulfide; Kinetic and mechanistic aspects of the redox dissociation of P4S10 in 1-choronaphthalene.; P4S9, P4S7, S and undefined P sulfide are formed; Kinetics;

Reference yield:

tetraphosphorus decasulfide (15857-57-5) + tetraphosphorus nonasulfide (25070-46-6) + triphenylphosphine (603-35-0) → tetraphosphorus heptasulfide (263358-58-3)

Guidance literature:
