Technology Process of Triiodochromium

There total 17 articles about Triiodochromium 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:

4Cr(3+)*2H(1+)*7SO4(2-)=Cr4H2(SO4)7 + hydrogen iodide (10034-85-2) → chromium(III) iodide (13569-75-0)

Guidance literature:

In further solvent(s); byproducts: H2S, H2O, I2; boiling with HI soln.;;

DOI:10.1021/ja01337a005

Reference yield:

chromium(II) iodide + iodine (7553-56-2,12190-71-5,8031-47-8) → chromium(III) iodide (13569-75-0)

Guidance literature:

In neat (no solvent); react. of CrI2 with I2 vapor (1 atm) at 500 °C;;

DOI:10.1021/ja01167a063

Reference yield:

chromium (7440-47-3) + iodine (7553-56-2,12190-71-5,8031-47-8) → chromium(III) iodide (13569-75-0)
