Useful:

• Chemical Classes: Pesticides -> Dithiocarbamates (Pesticide)
• Canonical SMILES: C(CNC(=S)[S-])NC(=S)[S-].[Zn+2]
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood, nervous system, liver and thyroid. May cause an increase in cholinesterase activity. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
• Description: Zineb is a light-coloured powder/crystal and insoluble in water. Zineb is one of the nonsystemic (surface-acting) fungicides of the group ethylenebisdithiocarbamates (EBDCs). Zineb is a polymer of ethylene (bis)thiocarbamate units linked with zinc and used for the control and prevention of crop damage in the field and also to protect harvested crops from deterioration during storage or transport. Zineb was used to protect fruit and vegetable crops from a wide range of foliar and other diseases. It was available in the United States as wettable powder and dust formulations. Zineb can be formed by combining nabam and zinc sulphate in the spray tank.
• Uses: Zineb is a contact fungicide that provides protection against a wide variety of fungal diseases (including leaf spots, blights, rust, downy mildew, scab, etc.) in field crops, fruits, vines, vegetables, ornamentals, citrus and bananas.

Technology Process of Zineb

There total 2 articles about Zineb 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: 99.4%

carbon disulfide (75-15-0,12122-00-8) + ethylenediamine (107-15-3,85404-18-8) + zinc(II) chloride (7646-85-7,24359-56-6) → zinc ethylenebis(dithiocarbamate) (12122-67-7)

Guidance literature:

With sodium hydroxide; In water; Addn. of CS2 in portions at 20-30°C to a mixt. of an aq. soln. of several amines and of NaOH (H2O), heating of mixt. (1.5 h, 45-60°C), cooling and then treatment with soln. of ZnCl2.; Filtn. of ppt., washing, and drying.;
