Technology Process of Dithionite

There total 7 articles about Dithionite 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:

hydrogen sulfide (7783-06-4) + sulfur dioxide (7446-09-5,12143-17-8,89125-89-3) → sulfur (7704-34-9) + dithionite(2-) (14844-07-6)

Guidance literature:

NaX zeolite; In neat (no solvent); byproducts: H2O, polymeric S, c-S8; Reaction of SO2 and H2S on NaX zeolite at room temp..; UV spectra, IR spectra;

DOI:10.1016/0021-9517(88)90208-4

Reference yield:

sodium hydrogensulfite → 2Na(1+)*3Zn(2+)*4SO3(2-)=Na2SO3*3ZnSO3 + hydrogen sulfide (7783-06-4) + dithionite(2-) (14844-07-6)

Guidance literature:

With Zn-amalgame; SO₂ or H₂SO₄; byproducts: Zn(OH)2;

Reference yield:

ammonium bisulfite → ammonium sulfate + sulfuric acid (7664-93-9) + sulfur (7704-34-9) + dithionite(2-) (14844-07-6)

Guidance literature:

selenium; In not given; byproducts: H2O; at ambient temp. under H2 for 3 months;

upstream raw materials:
