Technology Process of Carbon diselenide

There total 19 articles about Carbon diselenide 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: 50.0%

tetrachloromethane (56-23-5) + hydrogen selenide (13940-22-2) → carbon diselenide (506-80-9)

Guidance literature:

In neat (no solvent); reaction of H2Se dild. with N2 and CCl4 vapor at 500°C;;

Reference yield: 40.0%

dichloromethane (75-09-2) → carbon diselenide (506-80-9)

Guidance literature:

With selenium; at 560 ℃;

Reference yield: 40.0%

selenium (7782-49-2) + dichloromethane (75-09-2) → carbon diselenide (506-80-9)

Guidance literature:

In neat (no solvent); reacted at 560°C; sream distillation, dried over anhydrous CaCl2, distilled through a column, distilled at atmospheric pressure; elem. anal., IR;

upstream raw materials:
