Technology Process of Potassium hydrosulfide

There total 1 articles about Potassium hydrosulfide 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:

hydrogen sulfide (7783-06-4) + potassium (7440-09-7) → KSH, low temperature (1310-61-8)

Guidance literature:

In neat (no solvent); in a glove box; react. of metal with liq. S-compd. at 340-420 K in an autoclave; loading polycrystalline samples in glass capillaries under dry Ar (preventing decompn. by moisture), annealing of glass capillaries at 420 K for several weeks, slowly cooling down to room temp. (improving crystallinity);
