Technology Process of Ammonium methyldithiocarbamate

There total 1 articles about Ammonium methyldithiocarbamate 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) + methylamine (74-89-5) → N-methylcarbamodithioic acid ammonium salt (39680-90-5)

Guidance literature:

With ammonium hydroxide; In water; at 25 - 30 ℃; for 3h; Sealed tube;

Reference yield: 41.0%

N-methyl-N-chloromethylcarbamoyl chloride (50778-91-1) + N-methylcarbamodithioic acid ammonium salt (39680-90-5) → dazomet (533-74-4) + 3,5-Dimethyl-2-thioxo-[1,3,5]thiadiazinan-4-one (78460-59-0)

Guidance literature:

With triethylamine; In acetone; 1.)ice-water cooling, 1h 2.)r.t., 2 h;

Reference yield:

methyl-dithiocarbamic acid; ammonium salt (39680-90-5) + chloroacetyl chloride (79-04-9) → 3-Methyl-2-thioxo-thiazolidin-4-on (4807-55-0)
