Technology Process of Cesium triiodide

There total 4 articles about Cesium triiodide 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:

caesium tetraiodide → caesium triiodide(I) (20202-54-4) + iodine (7553-56-2,12190-71-5,8031-47-8)

Guidance literature:

In neat (no solvent); melts under decomposition on heating up to 136 °C forming CsI3 and I2;;

Reference yield:

iodine (7553-56-2,12190-71-5,8031-47-8) + cesium iodide → caesium triiodide(I) (20202-54-4)

Guidance literature:

In ethanol; the theoretical amount of I2 was dissolved in a soln. of CsI in a weak alcohol forming good crystals of CsI3;;

Reference yield:

2Cs(1+)*2I3(1-)*I2=Cs2I8 → caesium triiodide(I) (20202-54-4)

Guidance literature:

In neat (no solvent); decompn. in air;
