Abstract

A novel synthetic methods for the efficient and environmentally-friendly production will provide useful inspiration. This report presents a novel method for microwave-assisted synthesis of diazinon with different organic solvents, microwave heating power, heating time, catalysts. The optimal conditions for this synthesis are: 750W for microwave power, 12 min. for heating time, and 0.02% for mole ratio of catalyst DMAP to O, O-diethyl thiophosphoryl chloride and 1, 2-dichloroethane for the best solvent, which can lead the yield of diazinon to 67.86%. When adding repeatedly fresh 2-isopropyl-6-methyl-4-hydroxy pyrimidine for enough times, the yield of diazinon for O, O-diethyl phosphoryl chloride can be as high as 86.54%. With an amazing chemical reaction rate and less waste water discharge, microwave-assisted synthesis is a promising method for green synthesis.
