Synthesis of Thiadiazole Zineb
Procedia Engineering, 2011 AbstractIn this paper, a series of 2-amino-5-alkyl-1, 3, 4-thiadiazole zineb were prepared by reacting 2-amino-5-alkyl-1, 3, 4-thiadiazole, CS2 and ZnCl2. Its synthesis conditions was discussed. The optimal conditions were obtained as follows: reaction time 120min, reaction temperature 30°C, molar ratio n (thiadiazole): n (zinc chloride): n (CS2): n ...
