Synthesis of Thiadiazole Zineb

In 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 120 min, reaction temperature 30 °C, molar ratio n (thiadiazole): n (zinc chloride): n (CS2): n (NaOH) = 1:1:1.05:1.05, the products was synthesized in water. All compounds were characterized by elemental analysis, Infrared (IR)analysis to determine their structure.
