Technology Process of disulfur dioxide

There total 2 articles about disulfur dioxide 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:

sulfur dioxide (7446-09-5,12143-17-8,89125-89-3) → disulfur dioxide (126885-21-0) + sulfur trioxide (7446-11-9) + sulfur monoxide

Guidance literature:

In neat (no solvent); Irradiation (UV/VIS); photochemical decompn. of SO2 in light of a H2-lamp (wave length below 200 nm), about 10°C, 0.5 Torr, mechanism discussed;;

Reference yield:

sulfur monoxide → disulfur dioxide (126885-21-0) + sulfur dioxide (7446-09-5,12143-17-8,89125-89-3)

Guidance literature:

In neat (no solvent); mostly polymn. to S2O2 in gas phase, on further polymn. also decompn.;;

Reference yield: 80.0%

disulfur dioxide (126885-21-0) → sulfur dioxide (7446-09-5,12143-17-8,89125-89-3) + sulfur trioxide (7446-11-9) + sulfur (7704-34-9)

Guidance literature:

With oxygen; In neat (no solvent); oxidn. of S2O2 with an excess of O2, min. ignition pressure at 32°C 54 Torr, at 150°C 2 Torr, mechanism discussed, sometimes react. with lightening, inhibition by SO2;;
