Technology Process of Dihydroxidosulfur

There total 18 articles about Dihydroxidosulfur 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:

disulfur trioxide → polythionic acids + sulfuric acid (7664-93-9) + sulphurous acid (7782-99-2) + sulfur (7704-34-9) + sulfoxylic acid (20196-46-7)

Guidance literature:

With water; In water; decompn. of S2O3 when get into contact with H2O;; instant deposition of S, in filtrate: H2SO3, H2SO4, polythionic acids and H2SO2;;
