Technology Process of Calcium azide

There total 8 articles about Calcium 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:

ammonium azide + calcium (7440-70-2) → calcium azide (19465-88-4) + ammonia (7664-41-7) + hydrogen (1333-74-0)

Guidance literature:

In ammonia; addition of metallic Ca to a solution of NH4N3 in liquid NH3;;

DOI:10.1021/ja02224a009

Reference yield:

Ca(2+)*2N3(1-)*N2H4=Ca(N3)2*N2H4 → calcium azide (19465-88-4) + hydrazine (302-01-2,78206-91-4,119775-10-9,75013-58-0)

Guidance literature:

In neat (no solvent); heating for a longer time at 120°C;;

DOI:10.1021/ja01363a001

Reference yield:

hydrogen azide (7782-79-8) + calcium hydroxide → calcium azide (19465-88-4)

Guidance literature:

In water; neutralizing an aq. HN3-solution (5%) with Ca(OH)2;; recrystallization in Pt vessels; drying in vac. over H2SO4;
