Technology Process of dioxido-dioxo-chromium

There total 115 articles about dioxido-dioxo-chromium 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: 99.9%

chromium(III) oxide → chromate(VI) ion (13907-45-4,12381-48-5,76055-69-1)

Guidance literature:

With magnesium oxide; sodium carbonate; calcium oxide; further reagents; heating at 870°C for 12 h;

Reference yield: 60.0%

chromium (III) ion (16065-83-1) + manganese(II) (16397-91-4) → chromate(VI) ion (13907-45-4,12381-48-5,76055-69-1)

Guidance literature:

With oxygen; In not given; in basic soln. in 44 hours; 1 Mn : 8 Cr ratio;

Reference yield:

chromium(III) oxide + sodium chlorate → chlorine dioxide (10049-04-4,25052-55-5) + chromate(VI) ion (13907-45-4,12381-48-5,76055-69-1)

Guidance literature:

In water; excess of Cr(III); formation of ClO2 at 100°C;;
