Technology Process of AMMONIUM TETRATHIOTUNGSTATE

There total 11 articles about AMMONIUM TETRATHIOTUNGSTATE 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: 80.0%

sodium tungstate (VI) dihydrate (10213-10-2) + hydrogen sulfide (7783-06-4) → ammonium tetrathiotungstate (13862-78-7)

Guidance literature:

With NH₃; In water; addn. of dild. HCl to an aq. soln. of Na2WO4*2H2O; ppt. was isolated and dried; to the 'hydrated WO3' ammonia was added, the mixt. was stirred for 1 5. h, H2S was bubbled through the soln.; the mixt. was allowed to stand for 4 d;; ppt. was filtered;;

Reference yield: 63.0%

tungstic acid → ammonium tetrathiotungstate (13862-78-7)

Guidance literature:

With hydrogen sulfide; ammonia; In water; H2WO4 treated with concd. NH4OH, slurry saturated with H2S at room temp., heated at 60°C with stirring for 20 min, filtered, heated at 60°C, H2S bubbling continued for 8 h, cooled to 15°C while maintaining H2S flow; filtration, washing with i-PrOH and Et2O, drying in vac.; elem. anal.;
