Technology Process of POTASSIUM DISULFIDE)

There total 22 articles about POTASSIUM DISULFIDE) 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:

potassium sulfate + hydrogen (1333-74-0) → potassium disulfide (1336-23-8) + potassium sulfide + hydrogen sulfide (7783-06-4) + water (7732-18-5) + potassium hydroxide

Guidance literature:

quartz flow reactor at 1033 - 1073 K;; Kinetics;

Reference yield:

potassium thioacyanate (333-20-0) + magnesium (7439-95-4) → potassium disulfide (1336-23-8) + magnesium nitride + magnesium sulfide + pyrographite (7440-44-0)

Guidance literature:

Very vigorous reaction.;

Reference yield:

sulfur (7704-34-9) + potassium hydroxide → dipotassium trisulfide (37488-75-8) + potassium pentasulfide (12136-50-4) + potassium disulfide (1336-23-8) + potassium tetrasulfide (12136-49-1)

Guidance literature:

With hydrogen sulfide; In not given; KOH soln. is satd. with H2S, alcoholic soln. of S;

upstream raw materials:

potassium thioacyanate

magnesium

hydrogen

aluminium

Downstream raw materials:
