Technology Process of Caesium azide

There total 10 articles about Caesium azide 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: 99.0%

sodium azide + caesium carbonate (534-17-8) → cesium azide (22750-57-8)

Guidance literature:

In water; byproducts: CO2; elution of NaN3 through cation exchange column (prepared by HCl) to Pt dish, containing Cs2CO3; pH monitored; neutralization (pH 7); extensive description of apparatus and handling given;; evapn.; drying (110°C); identification by X-ray powder spectra;;

DOI:10.1016/0022-5088(86)90153-0

Reference yield: 95.0%

nitrogen (7727-37-9) + caesium (7440-46-2) → cesium azide (22750-57-8) + caesium nitride (12134-29-1)

Guidance literature:

In neat (no solvent); reaction of Cs with activated N2 (electric discharge) with formation of CsN3 and some Cs3N;;

Reference yield:

hydrogen azide (7782-79-8) + cesium hydroxide → cesium azide (22750-57-8)

Guidance literature:

In not given; CsOH was neutralized with HN3, the azide crytd. from the weak acidic soln. on standing over H2SO4;;

upstream raw materials:

nitrogen

caesium

cesium chloride

caesium carbonate

Downstream raw materials:
