Technology Process of Disulfur dinitride

There total 3 articles about Disulfur dinitride 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: 100.0%

poly(sulfur nitride) (12033-56-6) → disulfur (23550-45-0,12597-02-3) + dinitrogen disulphide (25474-92-4) + tetrasulphur dinitride (79796-31-9) + (S3N3) (79796-30-8) + tetrasulfur tetranitride (28950-34-7)

Guidance literature:

In neat (no solvent, gas phase); by heating to 130-150°C at low pressure; at temp. > 450°CS2, N2, S2N2 are produced; at temp. < 130°C S4N2, S4N4, S2N2 areproduced; various product ratio for various conditions; further products; detected by He I photoelectron spectroscopy and quadrupole mass specrometry;

Reference yield:

S4N4*2BeCl2=S4N4(BeCl2)2 → beryllium(II) chloride (7787-47-5) + dinitrogen disulphide (25474-92-4) + S4N4*BeCl2=S4N4BeCl2 + tetrasulfur tetranitride (28950-34-7)

Guidance literature:

In neat (no solvent); 6 h at 75-80°C, 1E-3 mbar;

Reference yield:

CuBr*tetrasulfurtetranitrid → dinitrogen disulphide (25474-92-4) + tetrasulfur tetranitride (28950-34-7) + copper(I) bromide (7787-70-4)

Guidance literature:

In neat (no solvent); heated at 180°C in vac. for 10 min; XRD;
