Technology Process of Diselenium

There total 11 articles about Diselenium 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:

selenium (7782-49-2) + bismuth selenide iodide + iodine (7553-56-2,12190-71-5,8031-47-8) → selenium dimer (12185-17-0) + bismuth(III) iodide (7787-64-6)

Guidance literature:

In neat (no solvent); transport reaction (evacuated silica tubes, T1: 713 K, T2: 693, 683, 673, 663, 653, 643 and 633 K or T1: 693 K, T2: 673, 663, 653, 643, 633, 623 and 613 K); thermodynamic measurments; Kinetics;

Reference yield:

selenium (7782-49-2) + SbSeI + iodine (7553-56-2,12190-71-5,8031-47-8) → selenium dimer (12185-17-0) + antimony triiodide (7790-44-5)

Guidance literature:

In neat (no solvent); transport reaction (evacuated silica tubes, T1: 673 K, T2: 653, 643, 633, 623, 613, 603 and 593 K or T1: 653 K, T2: 633, 628, 623, 618, 613, 608, 603 and 593 K); thermodynamic measurments; Kinetics;

Reference yield:

lead(II) gallium selenide → lead (7439-92-1) + selenium dimer (12185-17-0) + gallium(I) selenide + PbGa2

Guidance literature:

In neat (no solvent); by vaporizing from tantalum Knudsen cells in the range 600-1300 K; monitored by mass-spectroscopy;
