Technology Process of Lanthanum

There total 3 articles about Lanthanum 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:

lanthanum (7439-91-0) + hydrogen (1333-74-0) → lanthanum hydride + lanthanum trihydride (13864-01-2) + (hydrogen)lanthanum dihydride + LaH4(1-) (64883-89-2)

Guidance literature:

In gaseous matrix; Irradiation (UV/VIS); laser-ablated La atoms co-deposited with 5% H2 in excess of Ar at 3.5 K for 60 min, annealed to 16 K; not isolated; monitored by IR;

DOI:10.1021/ja020112l

Reference yield:

lanthanum (7439-91-0) + hydrogen (1333-74-0) → lanthanum trihydride (13864-01-2)

Guidance literature:

at 399.84 ℃; for 10h; under 7600.51 Torr;

DOI:10.1021/jacs.7b05746

Reference yield:

lanthanum (7439-91-0) + titanium dihydride (7704-98-5) → lanthanum trihydride (13864-01-2)
