Technology Process of Arsenous acid

There total 28 articles about Arsenous acid 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:

cobaltite (1303-15-7) → arsenous acid (13464-58-9) + sulphurous acid (7782-99-2)

Guidance literature:

In neat (no solvent); upon heating in a open tube arsenous acid and sulfurous acid are formed;;

DOI:10.1021/ja02066a012

Reference yield:

maucherite → arsenous acid (13464-58-9) + nickel (7440-02-0)

Guidance literature:

With air; In neat (no solvent);

Reference yield:
