Technology Process of LANTHANUM SULFIDE

There total 15 articles about LANTHANUM SULFIDE 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(III) sulfide + sulfur (7704-34-9) → lanthanum disulfide (12325-81-4)

Guidance literature:

1 d at 400°C, 1 d at 500°C, 5 d at 600°C; 20% excess of sulfur; cooling down and washing with CS2;

Reference yield:

lanthanum methoxide (10044-94-7) → LaS2, cubic (12325-81-4)

Guidance literature:

With hydrogen sulfide; In methanol; H2S bubbling into reaction flask (in fume hood) (25-85°C, 0.5-24 h); methanol removal (vac. evapn. at -10°C); grinding (agate mortar, glove box, inert gas); heat treatment at 500°C in H2S atmosphere; X-ray diffraction;

Reference yield:

lanthanum (7439-91-0) + sulfur (7704-34-9) → lanthanum disulfide (12325-81-4)

Guidance literature:

from the elements (La:S=2:3) by transport react. with iodine as carrier gas (5 to 6 mg/ml) in ampules with temp. gradient of 750/650°C;
