Technology Process of Phosphorus hepta sulfide

There total 45 articles about Phosphorus hepta sulfide 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: 34.0%

phosphorus sulfide (1314-85-8) → phosphorus sulfide (12037-82-0)

Guidance literature:

With I₂; In carbon disulfide; byproducts: PI3; react. of iodine in CS2 with P4S3;;

Reference yield:

phosphorous (12185-10-3) → diphosphorus tetraiodide (13455-00-0) + phosphorus sulfide (12037-82-0) + phosphorous + phosphorous triiodide (13455-01-1) + α-P4S3I2 (19257-89-7,92356-56-4)

Guidance literature:

With sulfur; at 125°C P4S7, P4S3I2, PI3 are products;

Reference yield:
