Technology Process of Silicon disulfide

There total 4 articles about Silicon disulfide 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:

silicon monosulfide (12504-41-5) + fluorine (7782-41-4) → silicon disulfide (13759-10-9) + difluorosilanethione (110661-62-6) + F3SiSH (95665-02-4) + SiS*F2 + silicon tetrafluoride (7783-61-1)

Guidance literature:

In solid matrix; Ar matrix; IR-monitoring;

DOI:10.1002/(sici)1099-0682(199911)1999:11<2013::aid-ejic2013>3.0.co;2-k

Reference yield:

carbon oxide sulfide (463-58-1) + silicon (7440-21-3) → silicon disulfide (13759-10-9)

Guidance literature:

With H₂S; In neat (no solvent); Irradiation (UV/VIS); (Ar); H2S was passed over heated Si at about 1500 K, formed SiS and a mixt. of COS and Ar (200:1) was cocondensed about 30 min on a helium-cooled Cu surface and photolysed with a medium pressure Hg lamp (H2O filter); not isolated, detected IR spect.;

Reference yield:

silicon monosulfide (12504-41-5) + carbon oxide sulfide (463-58-1) → silicon disulfide (13759-10-9)

Guidance literature:

In solid matrix; byproducts: CO; other Radiation; 20-25 K, CH4 matrix, photolysis (10 min, Hg lamp); not isolated, followed by Raman spectroscopy;
