Technology Process of SODIUM TRISULFIDE ANHYDROUS

There total 15 articles about SODIUM TRISULFIDE ANHYDROUS 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: 96.0%

sodium (7440-23-5) + sulfur (7704-34-9) → sodium trisulfide (37488-76-9)

Guidance literature:

In neat (no solvent); Sodium is melted in the molybdenum beaker by heating to 100-150°C, sulfur is added slowly, 3-4 h heating to about 300°C, inert atm.; cooling to room temp.;;

Reference yield:

sodium carbonate (497-19-8) + sulfur (7704-34-9) → sodium trisulfide (37488-76-9) + sodium sulfate (7757-82-6)

Guidance literature:

In neat (no solvent); heating of Na2CO3 with excess of S in a stream of CO2 at red heat; product mixture is obtained;;

Reference yield:

sodium sulfide (1313-82-2) + sulfur (7704-34-9) → sodium tetrasulfide + sodium trisulfide (37488-76-9) + sodium pentasulfide + sodium disulfide (22868-13-9)

Guidance literature:

In ethanol; partial evapn. in vacuum; at 15°C;

upstream raw materials:

sulfur

sodium

sulfur

hydrogen sulfide

Downstream raw materials:

tetrabutylammonium hexasulfide

sodium sulfide
