Technology Process of dipotassium trisulphide

There total 18 articles about dipotassium trisulphide 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:

carbon disulfide (75-15-0,12122-00-8) + potassium carbonate (584-08-7) → dipotassium trisulfide (37488-75-8) + pyrographite (7440-44-0)

Guidance literature:

flowing of CS2 vapor through glowing K2CO3;

Reference yield:

potassium dichromate → potassium thiosulfate + potassium sulfide (37488-75-8) + Sulfate (14808-79-8) + sulfur (7704-34-9)

Guidance literature:

With hydrogen sulfide; In water; byproducts: Cr(OH)3, Cr-thiosulfate; passing a slow H2S-stream through a 5% soln. of K2Cr2O7 at room temp., mechanism discussed;; brown pptn., after 4 hours green pptn. of Cr(OH)3, Cr-thiosulfate and S, filtrate contains K2S2O3 and K2S3 (at room temp.), below a critical value of OH(1-)-concn. sulfate is formed;;

Reference yield:

potassium hydroxide → potassium thiosulfate + potassium sulfide + K2S6 + potassium sulfide (37488-75-8) + K2S5

Guidance literature:

With sulfur; In water; isopropyl alcohol; with abs. or 91-98% isopropanol soln. of KOH; adding S to the reaction mixt. tri- penta and hexasulfide formed from monosulfide;
