Technology Process of Dipotassium trithiocarbonate

There total 19 articles about Dipotassium trithiocarbonate 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: 75.3%

carbon disulfide (75-15-0,12122-00-8) + hydrogen sulfide (7783-06-4) + potassium ethoxide (917-58-8) → potassium trithiocarbonate (584-10-1)

Guidance literature:

In ethanol; mixing of soln. of potassium ethoxide in ethanol with CS2; warming to 25°C; saturation with H2S for 2.5 h; warming to 45°C; slowlyaddn. of CS2 (over approximately 30 min); stirring; pptn., stirring for 1.5 h at 45°C, cooling to 0°C, holdingat that temp. for 1 h, filtration, washing 3 times with cold ethanol, d rying in vac. over P2O5 at 80°C for a week; elem. anal;
