Technology Process of Disilver oxide

There total 86 articles about Disilver oxide 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: 97.0%

silver nitrate → silver(II) oxide (11113-88-5,155645-89-9)

Guidance literature:

With Na₂SO₃; O₂ or air; In water; distd. H2O heated at 70°C, CO2-free NaOH added to adjust pH 10.53+/-0.03, O2, Na2SO3 added to achieve a oxidation potential of 600mV, AgNO3 in H2O added without changing the oxidation potential; washed to make free of alkali and nitrate, filtered, dried at 1580Pa, 70°C;

Reference yield: 96.0%

dipotassium peroxodisulfate + silver nitrate + potassium hydroxide → silver(II) oxide (11113-88-5,155645-89-9)
